Week 8 — Readings & Resources

Human Anatomy and Physiology I Free sample edition

Your primary reading is Chapter 8 (in this module). Everything below is the optional, go-deeper layer — pick what helps, skip the rest.

How to use this page

This page has 10 items (4 readings and 6 videos). Allow 48–55 minutes for everything. Each group points back to the matching chapter section and class-session segment, so use the full menu when one topic still feels shaky, or take the quick path below.

Every video here has captions: turn them on with the CC button in the player. The chapter covers the same ideas in text.

Pick-one quick path (18–20 min total)

① Keeping the loop pointed the right way

Chapter 8, Section “Read the loop: organization and homeostasis” · Session 1, Segment 1, “Read the loop: organization and homeostasis” · Remember: the receptor senses, the control center compares, and the effector reverses the change.

Positive and Negative Feedback Loops — Bozeman Science — a board-and-diagram walk through negative feedback, which pushes a value back toward its target, and positive feedback, which amplifies a change until something ends it; it also reaches for examples beyond the human body, so for each one say which way the loop pushes and name its receptor, control center, and effector. (video, 14 min) (captions: creator)

② Reading the cell from its own side

Chapter 8, Section “Read from the cell's side: organelles and tonicity” · Session 1, Segment 3, “Read from the cell's side: organelles and tonicity” · Remember: compare the bath with the cell, name the bath, then say where the water goes.

Hypertonic, Hypotonic and Isotonic Solutions! — BOGObiology — a short whiteboard explainer of what happens to a cell in each of the three kinds of solution; before each case is revealed, run the chapter's three moves yourself and check that you named the bath, not the cell. (video, 5 min) (captions: creator)
Cellular Respiration Overview: Glycolysis, Krebs Cycle and Electron Transport Chain — 2 Minute Classroom — a quick animated pass through the stages of respiration; it may count the step that carries pyruvate into the mitochondrion as its own stage and may quote one ATP total, so match its stages to the chapter's three and hold any total as an estimate. (video, 5 min) (captions: automatic)
Mitochondria — National Human Genome Research Institute Talking Glossary — a short definition of the organelle that makes most of a cell's ATP; read the definition and use it to say the organelle-to-job pair in one line, then skip the parts on mitochondrial inheritance, which this course does not cover. Use it while working through the Week-8 module overview. (reading, 2–4 min)

③ Keeping the bone pairs apart

Chapter 8, Section “Keep the bone pairs apart: shaft, texture, and cells” · Session 2, Segment 6, “Keep the bone pairs apart: shaft, texture, and cells” · Remember: the diaphysis is the shaft, spongy bone has no osteons, and blast builds while clast resorbs.

BONE STRUCTURE — Neural Academy — a short animated tour of a long bone and the tissue inside it; pause when compact and spongy bone appear and say which one is built from osteons and which one is a lattice of trabeculae. (video, 5 min) (captions: creator)
Bone Remodeling Mechanism — Hussain Biology — a brief explainer of how bone is broken down and rebuilt through life; every time a cell is named, say its job with the one-breath rule before the video does. (video, 4 min) (captions: automatic)
Structure of Bone Tissue — SEER Training Modules, National Cancer Institute — a plain reference page on compact and spongy bone, the osteon and its central canal, and the cells that build and break down bone. This builds on Week 7's work with bone as a living tissue: read it as a check on the three pairs, not as new material. (reading, 4–6 min)

④ Running the three-step read

Chapter 8, Section “Use the three-step read: name it, say its job, stop” · Session 2, Segment 7, “Use the three-step read: name it, say its job, stop” · Remember: name the structure, state its function, name one clinical connection, and stop.

Physis, Epiphysis, Metaphysis and Diaphysis in 3 Minutes — Air Anatomy — a fast labeled walk along a long bone; the physis is another name for the epiphyseal plate, so use the video to finish the first two steps of the read on that plate: where it sits and what it does. (video, 3 min) (captions: automatic)
Growth Plate Injuries — National Institute of Arthritis and Musculoskeletal and Skin Diseases — a plain-language health page on the growing zone near the ends of a child's long bones and why it can break; read the overview and the part on who gets these injuries as the clinical connection step, and stop before the diagnosis and treatment tab, which goes past this course's stopping point. Stop here before the named bones and joints; next week takes that up. (reading, 4–6 min)

Optional one-stop reference (free online reference)

Bone Development & Growth — SEER Training Modules, National Cancer Institute — the course's free online anatomy reference, open at its short page on how bone forms, lengthens at the epiphyseal plate, and remodels; read the parts on the plate and on remodeling, and skip the hormone details, which this course names only as loop parts. (reading, 2–3 min)

Heads-up (links rot): these point to outside sites that occasionally move or rename pages. If a link ever fails, tell your instructor and use the reference above in the meantime.
