Week 1 — Quiz (auto-graded) · Body Organization, Homeostasis & Anatomical Terminology

Course: Anatomy & Physiology I (BIOL 2301 + BIOL 2101) · Silver Oak University (fictional sample) · Prof. Navarro
Objective tested: Objective 1 — anatomy vs. physiology; levels of organization; characteristics of life & survival needs; homeostasis & feedback; anatomical position, directional terms, planes, and cavities.
Points: 10 (1 each) · Assignment group: Quizzes (10% of grade) · Due: end of Module 1.

This is the human-readable quiz with its vetted answer key and feedback. The import-ready Classic QTI is in F-quiz-week-01-qti.xml (generated by the shared validated script — parses with 10 items, every single-answer item exactly one correct). The reusable item-bank entries and the Canvas placement block are at the bottom of this file.

No trick questions; distractors target the Week 1 misconceptions named in the lecture outline.

Questions, key, and feedback

Q1 (MC). Which statement best distinguishes anatomy from physiology?
- A. Anatomy studies how parts function; physiology studies what parts there are
- B. Anatomy studies structure (what the parts are and where); physiology studies function (how they work) ✅
- C. They are two names for exactly the same field
- D. Anatomy studies living bodies; physiology studies only dead specimens
Feedback: Anatomy = structure; physiology = function — and the two are inseparable because structure determines function. (A reverses the two; C ignores the structure/function split; D is false — physiology studies living function.)

Q2 (MC). Which lists the levels of structural organization correctly from smallest to largest?
- A. cellular → chemical → tissue → organ → organ system → organism
- B. chemical → cellular → tissue → organ → organ system → organism ✅
- C. chemical → tissue → cellular → organ → organism → organ system
- D. cellular → chemical → organ → tissue → organism → organ system
Feedback: Atoms and molecules (chemical) build cells, which form tissues, which build organs, which cooperate as organ systems, which together make the organism. Each level is built from the one below it.

Q3 (Multiple answer — select all that apply). Which of the following are survival needs the body must keep within range?
- A. Nutrients ✅
- B. Oxygen ✅
- C. A constant supply of bright sunlight
- D. Water ✅
- E. Normal body temperature ✅
Feedback: The body's survival needs are nutrients, oxygen, water, normal body temperature, and appropriate atmospheric pressure. Sunlight is not a direct human survival need (we are not photosynthetic) — that's the distractor.

Q4 (MC). When you overheat, your body sweats and your skin's blood vessels dilate, cooling you back toward 37 °C. This is called negative feedback because the response —
- A. amplifies the change, pushing your temperature even higher
- B. opposes the change, bringing the variable back toward the set point ✅
- C. is harmful to the body
- D. permanently resets the body's set point to a new value
Feedback: Negative feedback opposes/reverses the change and restores the set point — the body's everyday workhorse (temperature, glucose, blood pressure). "Negative" means direction (it cancels the change), not "bad." Positive feedback would amplify the change.

Q5 (MC). In anatomical position (standing erect, facing forward, palms facing forward), the thumb is —
- A. medial to the other fingers
- B. lateral to the other fingers ✅
- C. superior to the other fingers
- D. deep to the other fingers
Feedback: Because the palms face forward in anatomical position, the thumb rotates to the lateral (outer) side. Students say "medial" by picturing a relaxed hand — but every directional term assumes anatomical position.

Q6 (Matching). Match each directional term to its meaning.
| Term | Correct meaning |
|---|---|
| Superior | Toward the head (upper) |
| Anterior | Toward the front of the body |
| Proximal | Closer to the trunk or a limb's point of attachment |
| Superficial | Toward the body's surface |
Feedback: The classic pairs: superior = toward the head (vs. inferior); anterior/ventral = front (vs. posterior/dorsal); proximal = nearer the attachment, for limbs (vs. distal); superficial = toward the surface (vs. deep).

Q7 (MC). Which statement uses directional terms correctly?
- A. The wrist is proximal to the elbow
- B. The elbow is proximal to the wrist ✅
- C. The fingers are proximal to the wrist
- D. The elbow is distal to both the shoulder and the wrist
Feedback: Proximal means closer to the trunk/point of attachment. The elbow is closer to the trunk than the wrist, so the elbow is proximal to the wrist (and the wrist is distal to the elbow). A and C reverse it; D is false because the elbow is proximal — not distal — to the wrist.

Q8 (True / False). "The sagittal plane divides the body into anterior (front) and posterior (back) portions."
- True
- False ✅
Feedback: False. The sagittal plane divides the body into left and right. The frontal (coronal) plane is the one that divides anterior from posterior. These two are swapped constantly — anchor each plane to the two parts it makes.

Q9 (MC). Which plane divides the body into left and right portions?
- A. the frontal (coronal) plane
- B. the transverse plane
- C. the sagittal plane ✅
- D. only an oblique plane can do this
Feedback: The sagittal plane runs vertically and divides left from right (right down the middle = midsagittal). Frontal → front/back; transverse → top/bottom.

Q10 (MC). The diaphragm separates the thoracic cavity from the abdominopelvic cavity. The heart and lungs are located in the —
- A. abdominopelvic cavity
- B. thoracic cavity ✅
- C. cranial cavity
- D. vertebral (spinal) cavity
Feedback: The heart and lungs sit in the thoracic cavity, above the diaphragm. The abdominopelvic cavity (below the diaphragm) holds the digestive and pelvic organs; the cranial and vertebral cavities (dorsal) hold the brain and spinal cord.

Answer key (quick reference)

Quality gate (self-checked): each single-answer item has exactly one correct option; the multiple-answer item lists all four survival needs (A, B, D, E) and requires the sunlight distractor (C) to be left unselected; the matching item pairs four terms to four distinct meanings; every directional term, plane, and cavity is verified against standard anatomy (OpenStax §1.6). Anatomy-accuracy gate: PASS. No computation in this quiz, so no arithmetic to mis-key (Week 1 is conceptual; the quantitative pockets begin at Week 2's pH lab and Week 3's osmolarity).

Item-bank entries (for variants + the midterm/final)

All ten items are tagged course=BIOL2301 · week=1 · objective=1 · topic=organization-terminology-homeostasis and deposited in Item Bank: Week 1 — Body Organization & Terminology. The midterm (Week 8) and the per-term variant updates draw fresh items from this bank. (Tags: q1 anatomy-vs-physiology, q2 levels-of-organization, q3 survival-needs, q4 negative-feedback, q5 anatomical-position, q6 directional-terms-match, q7 proximal-distal, q8 sagittal-misconception, q9 planes, q10 cavities.)
