Body of pubic bone Body of pubic bone The body of pubic bone forms the wide, strong, medial and flat portion of the pubic bone which unite in the pubic symphysis. The rough superior edge of the "corpus", the pubic crest, ends laterally in the pubic tubercle. This tubercle, found roughly 3 cm from the pubic symphysis, is a distinctive feature on the lower part of the abdominal wall; important when localizing the superficial inguinal ring and the femoral canal of the inguinal canal. Its "internal surface" enters into the formation of the wall of the lesser pelvis and gives origin to a portion
Aphanosauria bone, although perhaps a small portion was open according to a notch near where the ischium contacts the illium (upper blade of the hip). The gracile femur (thigh bone) of aphanosaurs possesses a characteristic set of features which can be used to diagnose the group. The proximal (near) surface of the bone, which connects to the hip socket, has a deep groove on it, rather than simply being a flat articulation surface. In addition, the bone's distal (far) articulation, which connects to the lower leg bones, is concave. The proximal part of the femur also has several bumps (tubers) on
