A read of this page, with the plate.

Serratus anterior from the ribs to the anterior medial scapula — pictured from the front
The saw. From the front. Pins the blade. Long thoracic. If it fails, the blade wings. Lung or spleen as a question, not a swap of clothes.Illustration · site art, not a Kapel Draw.

Finger-like slips from the upper eight or nine ribs to the anterior medial border of the scapula. It protracts, upwardly rotates, and pins the blade to the chest wall. It works against the rhomboids. That opposition is mechanics, not a metaphor. Nerve: long thoracic, C5–C7. When it fails, the scapula wings. That is literacy of the fiber.

Lung or spleen

The handwritten chart allows both. Rib wall and breath suggest lung. Some AK doors sit it with spleen. In the lab you ask. You do not pick a house because you like the story. Grief may show. Self-blame may show. The muscle does not owe you a single myth. You name protract. You name the door that answers.

Practice

Stand facing a wall. Reach forward as if to push, without bending the elbow all the way. Feel the ribs under the scapula. That is serratus. Name lung and spleen as two possible maps. Ask which door is on.

Check

Serratus anterior and the rhomboids:

  1. Oppose each other around the scapula — protract versus retract ✓
  2. Always fire as one muscle on one door
  3. Share kidney as address, with iliopsoas

Opposition is the balance of the blade. Two fibers, two jobs. Kidney is the hip flexor.

You use this fiber by:

  1. Asking the body whether lung or spleen is the address — the chart left a fork ✓
  2. Parking it on liver with the rhomboids, because both move the blade
  3. Parking it on bladder with the erectors, because both sit on the trunk

Lung or spleen. You ask. Liver is rhomboid. Bladder is the column.

A true line on this hour:

  1. A bottle that finishes the feeling
  2. That opposition is mechanics, not a metaphor. ✓
  3. Opening a chakra by squeezing it

That opposition is mechanics, not a metaphor.

Practice on this hour is to:

  1. A dose you write from a yield
  2. Stand facing a wall. ✓
  3. A swap of clothes for the organ

Method before bottle. Trace what the lesson names.

The lab on this hour is for:

  1. A graded exam that invents the next curriculum
  2. Feeling and naming what the lesson maps — journal, not a bottle ✓
  3. A prescription pad for the lab name

Lab is literacy. Not a dose from the yield.

A Kapel cue from this board:

  1. Treating every hour as interchangeable production
  2. The handwritten chart allows both. ✓
  3. A fixed rainbow outline you must see to be gifted

The handwritten chart allows both.
