| The iliacus muscle, sharing a tendon with the psoas at the lesser trocanter, fans up and opens, lining the inside of each ilium. |
| An accessory spine behind the ileopectineal eminence occasionally provides an attachment site for the psoas minor muscle. |
| In one pound weight of the psoas muscles Fleming counted no less than 300 cysticerci. |
| In psoas abscesses the exudation extends beneath the sheath of the muscle or between the iliacus and the bone. |
| If the subjacent iliac and psoas muscles be implicated, the thigh is flexed upon the leg in decubitus. |
| The lateral cutaneous nerve of the thigh passes from the lateral border of psoas major across the iliac fossa to pierce the inguinal ligament. |
