0 one of the two muscles on each side of the body that go from each side of the spine to the top of the thigh bone
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.
