Chart 29-9: sarcoplasmic reticulum holding calcium, troponin, tropomyosin
Chart 29-9. Also 6-5 and 7-5. Reticulum holds calcium. Troponin waits. Tropomyosin on the actin.CGI copy of her Draw · Atlas keeps the original.
Chart 29-10: heme to myoglobin, glucose through Krebs to ATP
Chart 29-10. Also 6-6, 7-6, 28-6. The furnace the fiber spends. ATP named, not dosed.CGI copy of her Draw · Atlas keeps the original.
Chart 29-11: sarcomere at rest and contracted
Chart 29-11. Also 6-10 and 7-10. At rest. Contracted. Z-line. The slide. Already sat — tonight the wire’s landing.CGI copy of her Draw · Atlas keeps the original.

The fiber already covered — Courses 6, 7, 28. This hour is what the wire contributes at the plate: the end-plate as the axon’s last job, T-tubules as the hall the impulse still owns, calcium as the handoff. The reticulum, the slide, heme-to-myoglobin stay captions of work already named.

Her voice, from the class.

The wire lands — end plate, acetylcholine, second messenger handoff

Captions
Human teaching · audio · 0.9×

Practice

Name end-plate, T-tubules, the handoff. Point the old plates as already covered. Do not dose ATP because a caption came back.

Check

This hour’s job is:

  1. Reprint the fiber as Courses 6, 7, 28
  2. What the wire contributes at the plate — end-plate, T-tubules, the handoff ✓
  3. A dose of ATP

Cut the reprint-as-content.

The end-plate on this hour:

  1. Is sarcoplasmic reticulum
  2. The wire’s last job — the letter lands ✓
  3. Heme to myoglobin

Where the axon stops being a wire.

T-tubules on this hour:

  1. The slide
  2. The hall the wire uses — the impulse is still a nerve event as it dives in ✓
  3. 29-10’s furnace

The corridor the fiber did not invent.

The handoff is:

  1. The Z-line
  2. Calcium — the ion the wire hands over ✓
  3. A pill of ATP

The fiber’s shortening already covered.

Reticulum, slide, heme-to-myoglobin:

  1. New nervous-system content
  2. Captions of work already named — Courses 6, 7, 28 ✓
  3. This hour’s three boards

Already sat.

You do not write a dose from this practice because:

  1. This hour names the landing, not the fiber ✓
  2. A blood titer is a doctor's number
  3. Course 28 said so

The wire.

ATP on a caption that came back:

  1. A pill you dose
  2. Named, not dosed — do not dose because a caption came back ✓
  3. The end-plate

Practice.

If the room is a seizure on the landing:

  1. You prescribe calcium
  2. You stop ✓
  3. You reprint 29-11

The stop.

Nothing here is nervous-system content, as audited:

  1. Stands as a reason to reprint
  2. Answered — the wire at the plate is the content ✓
  3. Means cut the course

Give it the landing.

Courses 6, 7, 28 on this page:

  1. Are the teaching
  2. Are back-references — the wire is the teaching ✓
  3. Are molybdenum

That's the work.
