pubis

[pyo̅o̅′bis] pl. pubes

Etymology: L, pubes

one of a pair of pubic bones that join at the pubic symphysis and, with the ischium and the ilium, form the hip bone. The pubis forms one fifth of the acetabulum and is divisible into the body, the superior ramus, and the inferior ramus. The external surface of the pubis serves as the origin of the adductor longus, the obturator externus, the adductor brevis, and the proximal part of the gracilis. The internal surface of the pubis forms part of the anterior wall of the pelvis, giving origin to the levator ani and the obturator internus. The pubic crest affords attachment to the rectus abdominis, the pyramidalis, and the inguinal falx. The lateral part of the superior ramus of the pubis presents the superior, the inferior, and the dorsal surfaces. The superior surface presents the iliopectineal line. The inferior ramus gives origin to the gracilis, a part of the obturator externus, the adductor brevis, the adductor magnus, the obturator internus, and the constrictor urethrae. Compare ilium, ischium.
