psoas major muscle

His psoas major muscle, which lifts the leg for the next stride, has four times the normal cross-sectional area.

This plexus lies within the psoas major muscle.

They proceed anterior and inferior along the medial border of the psoas major muscles.

It emerges on the anterior surface of the psoas major muscle and divides into two branches:

As with all quadrupeds, the tenderloin refers to the psoas major muscle along the central spine portion, ventral to the lumbar vertebrae.

It passes outward on the psoas major muscle, and pierces the fascia transversalis, or passes through the deep inguinal ring.

Medial to the anterior inferior iliac spine is a broad, shallow groove, over which the iliacus and psoas major muscles pass.

The psoas minor is a long, slender skeletal muscle which, when present, is located anterior to the psoas major muscle.

Here the tendon of the psoas major muscle passes over the medial chamber and the tendon of the iliacus muscle runs over the lateral chamber.

The medial arcuate ligament (also medial lumbocostal arch) is a tendinous fascia that arches over the psoas major muscle as it passes through the diaphragm.

In humans, the ureters arise from the renal pelvis on the medial aspect of each kidney before descending towards the bladder on the front of the psoas major muscle.

The root of mesentery crosses the second and third parts of duodenum, abdominal aorta, Inferior vena cava, right ureter, right psoas major muscle, and right gonadal artery.

So you see we have a nerve that is vulnerable to being compromised in two places: 1) as individual nerves exit the spine and 2) as the nerve passes along the Psoas major muscle.

The lateral group nodes are located adjacent to the aorta, anterior to the spine, extending laterally to the edge of the psoas major muscles, and superiorly to the crura of the diaphragm.

The iliopsoas muscle is covered by the iliopsoas fascia, which begins as a strong tube-shaped psoas fascia, which surround the psoas major muscle as it passes under the medial arcuate ligament.

The Iliopsoas muscle consists of Psoas major muscle (and occasionally Psoas minor muscle) and Iliacus muscle, muscles with separate origins but a common insertion on the lesser trochanter of the femur.
