This is a student-facing review page. Read it, work the fresh practice, re-derive every number, and follow the dated plan. Then run the paired Exam-Prep Tutorial and take the Practice Final for active recall. (This guide points to those two — it does not repeat them.)

Integrity note for students. Every practice item and worked number on this page is a fresh variant — new scenarios and wording — with a vetted answer (the numbers pre-computed and re-verified). None of these are the live final questions. Working them builds the skill the final tests, the honest way.

What the final covers (read this first)


Exam	Final — cumulative, Weeks 1–15, all 8 Objectives
Format	20 items, 100 points (5 each). A mix of concept, scenario, and quantitative items: most give you a short situation, a process, or a figure (described in words) and ask you to name the structure or term, put the steps in order, or work the number. Expect multiple-choice, several matching items (for structure→function and "put the steps in order"), a multiple-answer item, and a couple of true/false. There IS arithmetic — a pH fold-change and a membrane-potential value — both with clean numbers.
Coverage (where the points are)	Obj 1 = 2 items (organization, terminology & homeostasis) · Obj 2 = 3 (chemistry, cells & metabolism) · Obj 3 = 3 (tissues & integument) · Obj 4 = 3 (skeleton & joints) · Obj 5 = 3 (muscle & contraction) · Obj 6 = 2 (nervous tissue & the action potential) · Obj 7 = 2 (CNS, PNS & ANS) · Obj 8 = 2 (the special senses). The back half — Objectives 5–8 — is 9 of 20, so budget the most time there (the midterm already covered Obj 1–4 plus the bone portion of 4).
Weight	The final is 25% of your course grade — the single biggest assessment in the course.
When it opens / where	Opens in the Week 16 module (the final-review-and-exam week); the window opens at the start of the module and the exam is due six days later. This guide and the exam-prep tutorial post before it so you can prepare. There is no weekly quiz, assignment, lab, or discussion in Week 16 — the final replaces them. AI is not permitted on the Final.
What to bring	Yourself, rested, scratch paper for the calculations, and the one-page concept sheet you build from this guide. The exam is name-it / order-it / work-it: read a scenario or figure, identify the structure or concept, choose the best answer.

How to use this guide. Each objective below has the same four parts: (A) the key ideas in plain language, (B) the definitions / structure→function / worked numbers, (C) the predictable mistakes and their cures, and (D) where to review in the module. After all eight objectives come fresh worked examples + self-check questions (with answers), a dated study plan sized to finals week, and how it's graded + test strategy.

Objective 1 — Body Organization, Terminology & Homeostasis (Week 1) · 2 items

(A) Key ideas, plain language

Before any bone or nerve, do two things every clinician does: describe a location precisely and explain how the body stays in balance. Anatomy is the what's there; physiology is the what it does.

(B) Definitions, structure→function, figures

Anatomy vs. physiology: anatomy = structure; physiology = function. Structure determines function (a flat, flexible red blood cell bends through capillaries).
Levels of organization: chemical → cellular → tissue → organ → organ system → organism. A new ability emerges at each level.
Directional terms (from anatomical position — standing, palms forward): superior/inferior (head/feet), anterior/posterior (front/back), medial/lateral (midline/away — the thumb is lateral), proximal/distal (nearer/farther from the trunk — the elbow is proximal to the wrist), superficial/deep (surface/inside).
Body planes (name a plane by the two parts it separates): sagittal = left/right; frontal (coronal) = anterior/posterior; transverse = superior/inferior.
Body cavities: dorsal (cranial + vertebral) and ventral (thoracic + abdominopelvic, split by the diaphragm). The heart and lungs are thoracic.
Homeostasis & feedback: a stable internal environment; a feedback loop = receptor → control center → effector. Negative feedback reverses the change (the everyday workhorse — temperature, glucose, pH); positive feedback amplifies (childbirth, clotting).

(C) Predictable mistakes → cures

❌ Calls the thumb "medial." → ✅ In anatomical position (palms forward) the thumb is lateral.
❌ Swaps sagittal and frontal. → ✅ Sagittal = left/right; frontal = front/back.
❌ Puts the heart/lungs in the abdominal cavity. → ✅ They're thoracic (above the diaphragm).
❌ Thinks "negative feedback" is bad. → ✅ The names mean direction (reverse vs. amplify), not good/bad.

(D) Review in the module

Week 1 → Lecture Outline, Slides (Deck 1), Lecture Tutorial 1, Lab 1 ("Map the Body").

Objective 2 — The Chemistry of Life, Cells & Metabolism (Weeks 2–4) · 3 items

(A) Key ideas, plain language

Life runs on chemistry (atoms, water, pH), is built from cells (organelles + the membrane), and captures energy (ATP, respiration). Know the structure→function and the two quantitative pockets: pH and tonicity.

(B) Definitions, structure→function, worked numbers

Bonds: ionic = electrons transferred; covalent = shared; hydrogen bonds = weak attractions between molecules (give water its properties).
pH (quantitative): lower = more acidic; each unit = a 10× change in [H⁺]. So pH 3 vs 6 = 3 units = 10³ = 1000× more acidic; pH 5 vs 7 = 2 units = 100×. Blood is tightly held near 7.35–7.45; buffers resist pH change.
Biomolecules → monomers: carbohydrate ← monosaccharide; protein ← amino acid (shape → function); nucleic acid ← nucleotide; lipid = the exception (fatty acids + glycerol, no repeating monomer).
Organelles → function: nucleus (DNA/control), ribosome (protein synthesis), mitochondrion (ATP), lysosome (digestion), rough/smooth ER, Golgi (ship). The membrane is a phospholipid bilayer — selectively permeable.
Transport: passive (no ATP, down gradient) = diffusion, facilitated diffusion, osmosis (water moves toward higher solute); active (needs ATP, against gradient) = the Na⁺/K⁺ pump (3 Na⁺ out, 2 K⁺ in).
Tonicity (quantitative): hypotonic outside (less solute) → water in → cell swells; hypertonic (more solute) → water out → cell shrinks; isotonic → no net change. (Cell ~300 mOsm: in 100 → swells; in 500 → shrinks; in 300 → same.)
Metabolism (overview, in order): glycolysis (cytoplasm) → Krebs cycle (matrix, releases CO₂) → electron transport chain (inner membrane, O₂ = final acceptor, most ATP). ATP = the cell's energy currency.

(C) Predictable mistakes → cures

❌ "Higher pH = more acidic," or reports the pH difference as the factor. → ✅ Lower pH = more acidic; each unit is 10× (pH 3 vs 6 = 1000×).
❌ Reverses hypotonic/hypertonic. → ✅ Hypotonic outside → water in (swell); hypertonic → water out (shrink).
❌ "Osmosis moves solute." → ✅ Osmosis moves water, toward the higher solute.
❌ "Glycolysis makes the most ATP." → ✅ The ETC makes the most; glycolysis is first and nets little.

(D) Review in the module

Week 2 → Deck 2, Lab 2 (PhET pH). Week 3 → Deck 3, Lab 3 (osmosis/tonicity). Week 4 → Deck 4, Lab 4 (respiration/protein synthesis).

Objective 3 — Tissues & the Integumentary System (Weeks 5–6) · 3 items (back half — heavier)

(A) Key ideas, plain language

Four tissue types build every organ, and the skin is the first organ you study in depth. Lock structure → function and the epidermal layer order.

(B) Definitions, structure→function, figures

The four tissue types: epithelial (packed cells, avascular, basement membrane; covers/lines; classified by layers simple/stratified × shape squamous/cuboidal/columnar); connective (scattered cells in an abundant matrix; includes loose, dense, adipose, cartilage, bone, and blood); muscle (contracts — skeletal/cardiac/smooth); nervous (neurons + neuroglia; communicates). Blood is a connective tissue.
The skin, top → deep: epidermis (keratinized stratified squamous, avascular); dermis (connective tissue — vessels, nerves, glands, follicles); hypodermis (adipose; not part of the skin proper).
Epidermal strata, deep → superficial: stratum basale (deepest, new cells form) → spinosum → granulosum → (lucidum, thick skin only) → corneum (tough, dead, keratin barrier).
Pigment vs. toughness: melanin = UV-absorbing pigment (melanocytes); keratin = toughness (keratinocytes).
Functions: protection, thermoregulation (sweat + blood-vessel dilation/constriction — a homeostasis tie-in), sensation, vitamin D synthesis, excretion.

(C) Predictable mistakes → cures

❌ "The epidermis has lots of blood vessels." → ✅ The epidermis is avascular (fed by diffusion from the dermis).
❌ "Stratified = a single layer." → ✅ Simple = single; stratified = many.
❌ Scrambles the epidermal layers. → ✅ Anchor the ends: basale (new cells, deep) → … → corneum (barrier, top).
❌ Confuses melanin and keratin. → ✅ Melanin = color/UV; keratin = toughness.
❌ "Blood is muscle/epithelial." → ✅ Blood is connective tissue (cells in a fluid matrix).

(D) Review in the module

Week 5 → Deck 5, Lab 5 (virtual microscope / histology). Week 6 → Deck 6, Lab 6 (skin layers).

Objective 4 — The Skeletal System & Joints (Weeks 7, 9) · 3 items (back half — heavier)

(A) Key ideas, plain language

Bone is living, dynamic tissue. Know its jobs and cells, the axial/appendicular split, and how joints classify by mobility.

(B) Definitions, structure→function, figures

Bone functions: support, protection, movement (levers), mineral storage (Ca²⁺/phosphate), blood cell formation (hematopoiesis in red marrow), fat storage.
Gross long-bone anatomy: diaphysis (shaft), epiphysis (ends), epiphyseal plate (growth), periosteum (outer), medullary cavity (marrow).
Micro: compact bone = osteons (concentric lamellae around a central canal); spongy bone = trabeculae.
Bone cells (the classic mix-up): osteoBlast = Builds, osteoClast = Chews (resorbs, releasing Ca²⁺), osteocyte = maintains.
Skeleton split: axial = head + trunk (skull, vertebral column, ribs, sternum); appendicular = limbs + girdles (humerus, femur, clavicle, scapula, hip bones). Vertebral counts: cervical 7, thoracic 12, lumbar 5.
Joints by mobility: fibrous (immovable — skull sutures), cartilaginous (slightly movable), synovial (freely movable — fluid-filled cavity). Synovial types: hinge (elbow), ball-and-socket (shoulder/hip — greatest ROM), pivot (C1–C2), saddle (thumb). Movements: flexion/extension, abduction/adduction.

(C) Predictable mistakes → cures

❌ Swaps osteoblast/osteoclast. → ✅ Blast Builds; Clast Chews.
❌ Calls a limb bone "axial." → ✅ Limbs + girdles = appendicular; skull/spine/ribs = axial.
❌ "A suture is synovial." → ✅ Sutures are fibrous (immovable); synovial = freely movable.
❌ "Bone is inert." → ✅ Bone is living, continually remodeled tissue.

(D) Review in the module

Week 7 → Deck 7, Lab 7 (InnerBody skeletal). Week 9 → Deck 9, Lab 9 (bones & joints).

Objective 5 — Muscle Tissue & the Muscular System (Weeks 10–11) · 3 items (back half — heaviest)

(A) Key ideas, plain language

Muscles pull to move bones, and a contraction is a sequence of steps. Lock the sarcomere, the sliding-filament idea, and the order.

(B) Definitions, structure→function, worked process

Hierarchy: muscle → fascicle → fiber → myofibril → sarcomere (the contractile unit). Actin = thin, myosin = thick.
Sliding-filament model: myosin heads pull actin toward the center → Z discs draw closer → sarcomere shortens. The filaments SLIDE, they do not shorten.
Steps of contraction, IN ORDER: (1) motor neuron releases acetylcholine (ACh) at the neuromuscular junction; (2) an action potential sweeps the muscle fiber (down the T-tubules); (3) Ca²⁺ released from the sarcoplasmic reticulum; (4) Ca²⁺ binds troponin → tropomyosin moves off actin's binding sites; (5) cross-bridges form and the power stroke (using ATP) slides the filaments. Relaxation: ACh broken down, Ca²⁺ pumped back, tropomyosin re-covers.
The muscular system: origin (fixed attachment) vs. insertion (moving attachment); muscles work as agonist (prime mover) / antagonist / synergist. Key actions: biceps brachii flexes the forearm; triceps brachii extends it; deltoid abducts the arm; quadriceps extends the knee; hamstrings flex the knee. Muscles pull, they don't push.

(C) Predictable mistakes → cures

❌ "The filaments shorten." → ✅ They slide/overlap; their length doesn't change.
❌ Scrambles the steps. → ✅ ACh → AP → Ca²⁺ → troponin/tropomyosin → cross-bridge.
❌ "Calcium comes from the blood." → ✅ It's released from the sarcoplasmic reticulum.
❌ "The biceps extends the forearm." → ✅ The biceps flexes; the triceps extends.
❌ Reverses origin/insertion. → ✅ The insertion moves; the origin stays put.

(D) Review in the module

Week 10 → Deck 10, Lab 10 (sarcomere/grip-fatigue). Week 11 → Deck 11, Lab 11 (muscles & levers).

Objective 6 — Nervous Tissue & the Action Potential (Week 12) · 2 items (the quantitative pocket)

(A) Key ideas, plain language

A neuron sends signals as an ordered change in voltage. Keep the values and the phase order straight — that's the whole game.

(B) Definitions, structure→function, worked numbers

Neuron parts: dendrites (receive), soma (integrate), axon (conduct away), myelin (insulate → speeds conduction), nodes of Ranvier (saltatory conduction). Neuroglia support (Schwann cells myelinate in the PNS; oligodendrocytes in the CNS).
Resting membrane potential (quantitative): about −70 mV (inside negative), maintained by the Na⁺/K⁺ pump (3 Na⁺ out, 2 K⁺ in). Threshold ≈ −55 mV; peak ≈ +30 mV (the −70 → +30 swing = 100 mV).
Action potential, IN ORDER: (1) resting (−70 mV) → (2) depolarization (threshold reached → Na⁺ IN → inside positive, peak +30) → (3) repolarization (K⁺ OUT → inside negative again) → (4) hyperpolarization (brief dip below −70) → back to rest. All-or-none.
Synapse: the AP reaches the axon terminal → neurotransmitters released into the cleft → bind receptors on the next neuron.

(C) Predictable mistakes → cures

❌ "At rest the inside is positive." → ✅ It's negative (−70 mV).
❌ "Depolarization is K⁺ leaving." → ✅ Depolarization = Na⁺ IN; repolarization = K⁺ OUT.
❌ Scrambles the phases. → ✅ Resting → depol → repol → hyperpol.
❌ "Myelin slows the signal." → ✅ Myelin speeds conduction (MS, which damages it, slows signals).

(D) Review in the module

Week 12 → Deck 12, Lab 12 (PhET Neuron / reaction-time).

Objective 7 — The Central, Peripheral & Autonomic Nervous System (Weeks 13–14) · 2 items

(A) Key ideas, plain language

The brain has regions with jobs, and the autonomic nerves come in two opposing branches. Match region → function and sympathetic vs. parasympathetic.

(B) Definitions, structure→function, figures

CNS = brain + spinal cord. Cerebrum lobes: frontal (movement, planning, personality), parietal (touch), temporal (hearing, memory), occipital (vision). Cerebellum (coordination, balance). Hypothalamus (homeostasis — temperature, hunger, thirst). Medulla oblongata (vital centers — heart rate, breathing, blood pressure).
Protection: the meninges (outer → inner: dura → arachnoid → pia); cerebrospinal fluid (CSF) cushions; skull/vertebrae.
Reflex arc, in order: receptor → sensory (afferent) neuron → integration center → motor (efferent) neuron → effector.
PNS: 12 pairs of cranial nerves, 31 pairs of spinal nerves. Afferent = sensory (toward CNS); efferent = motor (away). Motor splits into somatic (voluntary) and autonomic (involuntary).
ANS — the key contrast: sympathetic = fight-or-flight (↑ heart rate, dilates pupils, opens airways, inhibits digestion) vs. parasympathetic = rest-and-digest (↓ heart rate, constricts pupils, stimulates digestion; the vagus nerve is its major nerve). They are antagonistic and maintain homeostasis.

(C) Predictable mistakes → cures

❌ "The occipital lobe handles hearing." → ✅ Occipital = vision; temporal = hearing.
❌ Meninges out of order. → ✅ Dura → arachnoid → pia (outer → inner).
❌ "Parasympathetic speeds the heart." → ✅ Sympathetic speeds; parasympathetic slows.
❌ Swaps afferent/efferent. → ✅ Afferent Arrives (sensory, toward CNS); Efferent Exits (motor, away).

(D) Review in the module

Week 13 → Deck 13, Lab 13 (InnerBody nervous / reflex). Week 14 → Deck 14, Lab 14 (autonomic heart-rate).

Objective 8 — The Special Senses (Week 15) · 2 items

(A) Key ideas, plain language

Each sense organ is structure → function. Lock the eye's parts and light path, the ear's hearing-vs-balance split and ossicle order, and that taste/smell are chemoreceptors.

(B) Definitions, structure→function, figures

Vision (eye): cornea (refracts), iris (controls pupil/light), lens (fine-focuses — accommodation), retina (photoreceptors), fovea (sharpest vision), optic nerve (to brain). Light path: cornea → pupil → lens → retina. Rods = dim light, no color; cones = color, bright light.
Hearing & equilibrium (ear): outer (pinna, canal) → middle (eardrum + ossicles malleus → incus → stapes, which amplify) → inner (cochlea = hearing; semicircular canals/vestibule = equilibrium/balance). Sound path: eardrum → ossicles → cochlea.
Taste & smell: taste buds detect 5 basic tastes — sweet, sour, salty, bitter, umami; smell uses olfactory receptors. Both are chemoreceptors, and both build flavor (which is why food tastes bland with a congested nose).

(C) Predictable mistakes → cures

❌ Reverses rods and cones. → ✅ Cones = color/bright; rods = dim/no color.
❌ Ossicles out of order. → ✅ Malleus → incus → stapes (hammer → anvil → stirrup).
❌ "The cochlea handles balance." → ✅ Cochlea = hearing; semicircular canals = balance.
❌ Forgets umami. → ✅ The five tastes include umami (not "spicy").

(D) Review in the module

Week 15 → Deck 15, Lab 15 (sensory demos / InnerBody eye & ear).

Representative practice (all fresh — vetted, pre-computed answers)

None of these are live final items. New scenarios, new wording. Each answer is vetted; the quantitative ones are pre-computed and were independently re-verified. Cover the answers, work each one (re-derive the numbers yourself), then check. Practice is weighted toward the heavier back half (Objectives 5–8).

Objective 1 practice

Worked example — directions, planes, homeostasis.
A nurse charts a wrist injury and slices a CT image.
- (a) Is the wrist proximal or distal to the elbow? (b) Which plane gives a single cross-sectional CT slice? (c) Is sweating to cool down negative or positive feedback?
Answer. (a) Distal (farther from the trunk). (b) The transverse plane (superior/inferior). (c) Negative feedback (the response reverses the temperature rise). Why: proximal/distal are relative to the trunk; a transverse cut is a cross-section; cooling opposes the change.

Self-check (Obj 1).
1. In anatomical position, the thumb is on which side? → Lateral.
2. Which plane divides the body into anterior and posterior? → Frontal (coronal).
3. The heart and lungs sit in which cavity? → Thoracic.
4. The three parts of a feedback loop are? → Receptor → control center → effector.

Objective 2 practice

Worked example — pH (quantitative) + tonicity (quantitative) + organelle.
A lab compares a fluid at pH 4 with one at pH 7, drops a 300 mOsm cell into a 500 mOsm solution, and asks which organelle makes ATP.
- (a) How many times more acidic is pH 4 than pH 7? (b) What happens to the cell? (c) Which organelle makes ATP?
Answer. (a) 1000× (3 units → 10³). (b) The solution is hypertonic, so water leaves and the cell shrinks. (c) The mitochondrion. Why: each pH unit is 10×; water moves toward the higher solute (out); mitochondria run respiration. (Pre-verified.)

Self-check (Obj 2).
1. How many times more acidic is pH 5 than pH 7? → 100× (10²).
2. A 300 mOsm cell in a 100 mOsm solution? → Swells (hypotonic, water in).
3. Which biomolecule is NOT built from a single repeating monomer? → Lipids (fatty acids + glycerol).
4. Put the respiration stages in order. → Glycolysis → Krebs cycle → electron transport chain.

Objective 3 practice — back half; work all of these

Worked example — tissues + skin layers.
A slide shows scattered cells in a fluid matrix; a second figure shows the layers of thick skin.
- (a) Blood is which of the four tissue types? (b) Order the epidermal strata deep → superficial. (c) Is the epidermis vascular?
Answer. (a) Connective tissue (cells in a matrix). (b) Basale → spinosum → granulosum → (lucidum) → corneum. (c) No — avascular (fed by diffusion from the dermis). Why: connective = matrix; new cells form at the basale; the epidermis has no vessels.

Self-check (Obj 3).
1. Stratified epithelium has how many layers? → Many (simple = one).
2. Which pigment absorbs UV? → Melanin (keratin = toughness).
3. Which skin layer makes new keratinocytes? → Stratum basale (deepest).
4. Which skin function is a homeostasis story? → Thermoregulation (sweat + vessels).

Objective 4 practice — back half; work all of these

Worked example — bone cells + skeleton + joints.
Blood calcium drops; a bone is classified; a joint is named.
- (a) Which cell releases calcium from bone? (b) Is a rib axial or appendicular? (c) Which synovial joint gives the greatest ROM?
Answer. (a) The osteoclast (Chews). (b) Axial (thoracic cage). (c) The ball-and-socket joint (shoulder/hip). Why: osteoClast resorbs; ribs are axial; ball-and-socket moves in all three planes.

Self-check (Obj 4).
1. Which cell builds bone? → Osteoblast (Builds).
2. The femur belongs to which division? → Appendicular.
3. A skull suture is which joint class? → Fibrous (immovable).
4. How many cervical vertebrae? → 7.

Objective 5 practice — back half; work all of these

Worked example — sarcomere + the steps in order.
A muscle fiber contracts.
- (a) Which is thin, actin or myosin? (b) Put the contraction steps in order. (c) Does the biceps flex or extend the forearm?
Answer. (a) Actin is thin (myosin thick). (b) ACh at the NMJ → action potential → Ca²⁺ from the SR → troponin/tropomyosin → cross-bridge/power stroke. (c) The biceps flexes the forearm. Why: actin = thin; the ordered sequence; the biceps is a flexor (the triceps extends).

Self-check (Obj 5).
1. The contractile unit of a muscle fiber is the? → Sarcomere.
2. In the sliding-filament model, do the filaments shorten? → No — they slide.
3. Where does the calcium for contraction come from? → The sarcoplasmic reticulum.
4. The attachment that moves is the? → Insertion (origin stays put).

Objective 6 practice — the quantitative pocket; work all of these

Worked example — resting potential + the AP phases.
A neuron sits at −70 mV, then fires.
- (a) Is the inside positive or negative at rest? (b) Put the AP phases in order and name the ion in each. (c) What's the voltage swing from rest to peak?
Answer. (a) Negative (−70 mV). (b) Resting → depolarization (Na⁺ in) → repolarization (K⁺ out) → hyperpolarization. (c) −70 to +30 = 100 mV. Why: resting is inside-negative; depol = Na⁺ in, repol = K⁺ out; the swing is 100 mV. (Pre-verified.)

Self-check (Obj 6).
1. During depolarization, which ion moves IN? → Sodium (Na⁺).
2. During repolarization, which ion moves OUT? → Potassium (K⁺).
3. Does myelin speed or slow conduction? → Speeds it.
4. Threshold is reached at about? → −55 mV.

Objective 7 practice — back half

Worked example — brain regions + the meninges + the ANS.
A patient has trouble with balance; a chart names the brain's coverings; a startle response fires.
- (a) Which brain region governs balance/coordination? (b) Order the meninges outer → inner. (c) Which ANS branch drives fight-or-flight?
Answer. (a) The cerebellum. (b) Dura → arachnoid → pia. (c) The sympathetic division. Why: cerebellum = coordination; meninges go dura→arachnoid→pia; sympathetic = fight-or-flight.

Self-check (Obj 7).
1. Which lobe processes vision? → Occipital.
2. Which structure runs homeostasis (temperature, hunger)? → Hypothalamus.
3. Afferent neurons carry signals which way? → Toward the CNS (sensory).
4. Which division slows the heart? → Parasympathetic (rest-and-digest).

Objective 8 practice — back half

Worked example — eye + ear.
A photo is taken in dim light; a sound passes through the middle ear.
- (a) Which photoreceptors work in dim light? (b) Order the ossicles from the eardrum inward. (c) Which inner-ear structure hears?
Answer. (a) Rods (dim, no color; cones = color/bright). (b) Malleus → incus → stapes. (c) The cochlea. Why: rods for dim light; the ossicle chain; the cochlea transduces sound.

Self-check (Obj 8).
1. Which photoreceptors detect color? → Cones.
2. What's the light path through the eye? → Cornea → pupil → lens → retina.
3. Which inner-ear structures handle balance? → The semicircular canals / vestibule.
4. Taste and smell use which receptor class? → Chemoreceptors.

Study plan — a dated countdown (finals week, sized to 2 sessions/week)

Built for the Week 16 final. Adjust the exact dates to your section's posted exam day; the rhythm is what matters. The final is cumulative and the back half (Obj 5–8) is the heaviest — once your foundations are warm, spend the most time there, and re-work every calculation by hand. Do a little every day rather than one long cram.

When	Do this (≈60–90 min)
~7 days out (end of Week 15)	Read this guide's Objectives 1–2 (organization & terminology; chemistry, cells & metabolism). Work the Obj 1 & 2 practice, including the pH factor and the tonicity prediction. Build your one-page concept sheet (the directional terms, the planes, the feedback loop, the pH 10×-rule, the tonicity directions, the organelle list).
~6 days out	Read Objective 3 (the four tissues, the skin layers) and Objective 4 (bone cells, axial/appendicular, joints). Work both practice sets; order the epidermal strata and classify a few bones and joints from memory.
~5 days out	Read Objective 5 (the sarcomere, the steps of contraction in order, the muscular system). Work all its examples; recite the five contraction steps and place actin/myosin and origin/insertion.
~4 days out	Read Objective 6 carefully — the membrane-potential pocket (resting −70 mV, the AP phases in order, which ion moves when). Re-derive the −70 → +30 swing and place each phase yourself.
~3 days out	Read Objective 7 (brain regions, the meninges, sympathetic vs. parasympathetic) and Objective 8 (the eye, the ear, taste & smell). Work both practice sets. Then run the paired Exam-Prep Tutorial (`N-exam-prep-tutorial-week-16`) in an approved chatbot — it diagnoses your weak spots across all 8 objectives and drills them.
~2 days out	Take the Practice Final (`O-practice-final-week-16`, the paired practice exam in this module) under timed, closed-note conditions (it allows multiple attempts — use the first as a real test). Score it; list every missed idea by objective.
~1 day out	Re-teach only the topics you missed on the practice final (use this guide's mistake-cures and the relevant Lecture Tutorial). Re-do those specific self-checks and re-work any missed calculation, with extra attention to Obj 5–8. Sleep.
Exam day	Skim your one-page concept sheet. Arrive early with scratch paper. Read each item twice; for every scenario, name the structure or concept (or set up the calculation) in your own words before looking at the options.

Two paired tools — use both (don't skip):
- Exam-Prep Tutorial (N-exam-prep-tutorial-week-16) — a copy/paste chatbot tutor that diagnoses, re-teaches, and drills you across all 8 objectives, ending with a readiness summary. Best for active recall and shoring up weak spots.
- Practice Final (O-practice-final-week-16, the paired practice exam in the Week 16 module) — a full, fresh run that mirrors the real format and the 20-item emphasis. Best for pacing and a final readiness check.

(This guide points to both on purpose — it doesn't duplicate them.)

How the final is graded + test-taking strategy

How it's graded.
- 100 points across 20 items (5 points each), a mix of concept, scenario, and quantitative items. The matching items award partial credit per correctly paired row; every numeric answer has one clean, pre-verified value.
- The final is 25% of your course grade — the largest single assessment. It replaces Week 16's quiz, assignment, lab, and discussion.
- Coverage matches this guide: Obj 1 = 2 · Obj 2 = 3 · Obj 3 = 3 · Obj 4 = 3 · Obj 5 = 3 · Obj 6 = 2 · Obj 7 = 2 · Obj 8 = 2. The back half (Obj 5–8) is 9 of 20 — practice it until the moves are automatic. AI is not permitted on the Final.

Honest test-taking strategies for this material.
1. Name the structure or concept before you read the options. For a scenario, say the term or trace the path first, then find the matching option — it blocks tempting distractors.
2. Work every calculation on scratch paper. pH = count the units, then 10^(units). Tonicity = water moves toward the higher solute. Don't do these in your head.
3. For process-order items, recite the sequence: contraction ACh → AP → Ca²⁺ → troponin/tropomyosin → cross-bridge; the action potential resting → depol → repol → hyperpol; respiration glycolysis → Krebs → ETC; the meninges dura → arachnoid → pia; the ossicles malleus → incus → stapes.
4. Keep structure→function straight with your one-page lists (mitochondrion = ATP; cornea = refract / lens = focus / retina = photoreceptors / iris = pupil; osteoblast = build / osteoclast = chew).
5. Watch the directional/reversible rules: osmosis (hypotonic → water in, cell swells); the thumb is lateral; depolarization = Na⁺ in / repolarization = K⁺ out; sympathetic speeds the heart, parasympathetic slows it.
6. Catch the planted misconception that should be marked false: "the epidermis is rich in blood vessels," "stratified epithelium is one layer," "the parasympathetic division speeds the heart," "rods detect color."
7. Don't confuse the look-alikes: ionic vs. covalent; actin vs. myosin; osteoblast vs. osteoclast; afferent vs. efferent; rods vs. cones; sagittal vs. frontal; origin vs. insertion.
8. For the orderings, anchor the ends first (deepest/most-superficial layer; first/last step), then fill the middle.
9. Do the easy items first, flag the hard ones, and budget your time — 20 items in the period is a few minutes each. Read each item twice and answer the question actually asked.

Term-update note: each term's $39 update regenerates fresh practice variants from this same scope — the live final is never reproduced here.

The per-term $39 update (fresh assessment variants, re-paced to your next calendar) referenced above is on the roadmap — coming soon. Today's download is yours to keep, but it doesn't refresh itself.
