Banner: the low-back cylinder — psoas, iliacus, rectus, oblique, quadratus
Banner. A cylinder. Front: psoas and iliacus to the lesser trochanter, the belly wall. Back: the square to the twelfth rib. Kidney, small intestine, large intestine as addresses. A lab that only palates the back will miss the front.Illustration · site art, not a Kapel Draw.
Psoas and iliacus — the front of the low-back cylinder
Turn the person around. The front of the cylinder. Kidney as address. A lab that only palates the back will miss them.Illustration · site art, not a Kapel Draw.
Quadratus lumborum from iliac crest to the twelfth rib
The square. Crest to twelfth rib. It does not insert on the sacrum. Large intestine as address.Illustration · site art, not a Kapel Draw.
Rectus abdominis and external oblique — the belly wall
The wall. Small intestine as address. Flex, compress, rotate opposite.Illustration · site art, not a Kapel Draw.

Class 2 turns the person around. Psoas and iliacus on the front of the lumbar spine and the iliac bowl, inserting on the femur. Rectus and the external obliques as the belly wall. Quadratus lumborum as the square in the back, crest to twelfth rib. Together they are a cylinder. A lab that only palates the back will miss the psoas and then name the erectors for a front job.

The maps on this wall

Kidney on iliopsoas. Small intestine on rectus and the external obliques. Large intestine on quadratus. Those are Kapel’s doors, sitting next to ordinary origins. Grief on metal, fear on water, sorting on small intestine — already in Course 01’s emotional tables. We reuse the language. Origin, insertion, action named. Meridian as address.

Practice

Switch the map to the front. Name psoas, rectus, oblique. Switch to the back. Name QL. One cylinder. Name the three doors.

Check

Iliopsoas is pictured from the:

  1. Front — lumbar spine and iliac fossa to the lesser trochanter ✓
  2. Back — crest to twelfth rib, with quadratus
  3. Medial border of the scapula

It is a deep anterior hip flexor. The back will name the wrong fiber if you never turn. QL is the square behind.

You use the cylinder by:

  1. Naming kidney on iliopsoas, small intestine on the belly wall, large intestine on QL ✓
  2. Parking the whole cylinder on bladder with the erectors, because they all hold the trunk
  3. Parking QL on kidney with psoas, because both say loin

Three doors, one cylinder. Bladder is the column above. Kidney is the hip flexor, not the square.

Those on this board are:

  1. A bottle that finishes the feeling
  2. Kapel's doors, sitting next to ordinary origins ✓
  3. A reason to prescribe from the chart

Those — Kapel's doors, sitting next to ordinary origins

This hour teaches that:

  1. Inventing a colorful story so the session feels complete
  2. A lab that only palates the back will miss the psoas and then name the erectors for a… ✓
  3. Collapse the map into one medical stamp

A lab that only palates the back will miss the psoas and then name the erectors for a front job.

Practice on this hour is to:

  1. Thyroxine from the medulla
  2. Switch the map to the front. ✓
  3. A dose you write from a yield

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.

"The low-back cylinder" here is best treated as:

  1. A tourist collection of special experiences
  2. Class 2 turns the person around. ✓
  3. A rigid diagnosis tool that replaces sleep

Train with the map. Do not invent a second sky.

The skilled response here is:

  1. Squeezing the gate until it 'opens'
  2. Psoas and iliacus on the front of the lumbar spine and the iliac bowl, inserting on the… ✓
  3. A board you invent without her permission

Psoas and iliacus on the front of the lumbar spine and the iliac bowl, inserting on the femur.

You use this lesson by:

  1. A swap of clothes for the organ
  2. Rectus and the external obliques as the belly wall. ✓
  3. Collapsing two houses into one word

Rectus and the external obliques as the belly wall.

A Kapel cue from this board:

  1. A name that captures the whole sky
  2. Quadratus lumborum as the square in the back, crest to twelfth rib. ✓
  3. A reason to skip permission

Quadratus lumborum as the square in the back, crest to twelfth rib.
