Examples of psoas

• Both psoas muscles were incised longitudinally and examined for the presence of cysticerci.

• Abdominal exercises could be avoided altogether if they stimulate too much the psoas and the other hip flexors.

• The psoas is the primary hip flexor, assisted by the iliacus.

• The plexus is formed lateral to the intervertebral foramina and passes through psoas major.

• It is joined by the iliacus, psoas major forms the iliopsoas which is surrounded by the iliac fascia.

• The pain elicited is due to inflammation of the peritoneum overlying the iliopsoas muscles and inflammation of the psoas muscles themselves.

• The iliacus originates on the iliac fossa to join psoas at the iliopubic eminence to form the iliopsoas which is inserted into the lesser trochanter.

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

• Imbalances in muscle strength and length are also a cause, such as weak hamstrings, or tight hip flexors (psoas).

• Though the iliopsoas is sometimes considered a member of the anterior compartment muscles, the iliacus and the psoas portions do not share the same innervation.

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

• It emerges from the lateral border of the psoas major just inferior to the iliohypogastric, and passes obliquely across the quadratus lumborum and iliacus.

• 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 lateral cutaneous femoral nerve pierces psoas major on its lateral side and runs obliquely downward below the iliac fascia.

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