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.

Mastoid part of the temporal bone The mastoid part of the temporal bone is the back part of the temporal bone.

Its outer surface is rough, and gives attachment to the occipitalis and posterior auricular muscles. It is perforated by numerous foramina (holes); one of these, of large size, situated near the posterior border, is
