Week 5 of 17
FEBRUARY 19 TO 24
Fiction. No real student, family or grade appears.

Should athletes be allowed drugs that build muscle faster? I said no and got asked why training at altitude is fine but a drug is not, since both are deliberate manipulation of physiology.

The sarcomere. Actin and myosin, Z-lines, A-band, I-band, and the sliding filament model.

This is the one people told me about. You roll actual clay muscles and place them on a skeleton model, in anatomical order, from origin to insertion.

That muscle is on backwards. The action you just described would be impossible.

Agonist, antagonist, synergist. Nothing in the body moves by one muscle contracting. One pulls, one resists, others stabilize, and the resistance is what makes the movement controlled instead of a spasm.

Sarcomere diagram, Maniken photos, muscle pair analysis. The packet works across scales, from filaments sliding to a whole joint moving, which is the point of the week.
