Psoas and iliacus — kidney
A read of this page, with the plate.

Psoas major from T12 and the lumbar bodies, discs, and transverse processes — not a vague ‘anterior lumbar’ — to the lesser trochanter. It flexes the hip and turns it slightly out. A guarded, short psoas can contribute to an anterior pelvic tilt and a louder lumbar curve. Can. Not must. Nerve: lumbar plexus, L1–L3. Depth is the point. You name the origin before you ask the fiber a yes or no.
Iliacus, the same tendon
Iliacus from the iliac fossa, same lesser trochanter, femoral nerve L2–L3. Together they are iliopsoas. Kapel puts both on kidney. Fear, the well, the reserve Course 01 already named on the kidney hours. You name flex. You name the door.
Her voice, from the class.
Psoas governed by the kidney meridian
Iliacus with psoas — kidney pair
Practice
Lie down if you can. Slide one heel long. Notice the front of the lumbar spine without poking it. Name lesser trochanter. Name kidney.
Check
Psoas major inserts on:
- The lesser trochanter of the femur ✓
- The twelfth rib, with quadratus
- The intertubercular groove, with latissimus
With iliacus, on the lesser trochanter. Twelfth rib is QL. The groove is lat.
You use iliopsoas in this hour by:
- Naming kidney as the address — fear, the well — and asking which of the pair is on ✓
- Parking it on large intestine with QL, because both sit at the loin
- Parking it on small intestine with rectus, because both are on the front
Kidney is the door. QL is metal. Rectus is small intestine.
A true line on this hour:
- A name that captures the whole sky
- You name the origin before you ask the fiber a yes or no. ✓
- A bottle that finishes the feeling
You name the origin before you ask the fiber a yes or no.
Practice on this hour is to:
- A swap of clothes for the organ
- Lie down if you can. ✓
- A reason to skip permission
Method before bottle. Trace what the lesson names.
The lab on this hour is for:
- A graded exam that invents the next curriculum
- Feeling and naming what the lesson maps — journal, not a bottle ✓
- A prescription pad for the lab name
Lab is literacy. Not a dose from the yield.
