What a finished product looks like

This is a model of the work you should turn in today. Use it to check your own: match the structure and the level of detail, do not copy it. Your data and wording should be your own.

Muscles-and-motion evidence packet and tracker

Completes: A combined evidence packet for the muscle week (sarcomere diagram, Maniken photos, agonist-antagonist analysis) with an updated weekly tracker and a reflection linking the sarcomere to whole-muscle motion.

Weekly tracker (muscle unit):

Labeled sarcomere diagram and contraction explanation: complete, dated. Done.
Maniken muscle build photos (anterior and posterior): complete, labeled. Done.
Agonist-antagonist analysis and revised labels: complete. Done.

Rubric self-check: every artifact dated, labeled, and accurate. Yes.

Two-sentence reflection: Movement starts at the sarcomere, where myosin pulls actin to shorten the muscle fiber. That microscopic shortening is what lets the biceps act as the agonist to flex the elbow while the triceps relaxes as the antagonist, so the molecular and joint levels connect.

Also due today: Submit as a combined PDF or folder upload by end of class.

WebXam problem for today's skill

One exam-style question that uses exactly what you practiced today. Try it before you reveal the answer, then read why each choice is right or wrong.

WebXam-style domain: Human Body Form, Function, and PathophysiologySelf-check skill: Linking sarcomere shortening to whole-muscle movement

A student says, 'When my biceps shortens to bend my elbow, that shortening starts inside the muscle.' At what structural level does that shortening begin?
