The posterior surface, convex from above downward, concave from side to side, is smooth, and forms part of the anterior wall of the pelvis.The adductor longus arises from the upper and medial angle, immediately below the crest lower down, the obturator externus, the adductor brevis, and the upper part of the gracilis take origin. The anterior surface is rough, directed downward and outward, and serves for the origin of various muscles.It consists of an inner flattened part and a narrow outer prismoid portion. It extends from the body to the median plane where it joins with the ramus of the opposite side. It forms the upper edge of the obturator foramen. The superior pubic ramus is the upper of the two rami. The inner surface of the body forms part of the wall of the lesser pelvis and joints to the origin of a part of the obturator internus muscle. 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. The rough upper edge is the pubic crest, ending laterally in the pubic tubercle. The bodies of the left and right pubic bones join at the pubic symphysis. The body forms the wide, strong, middle and flat part of the pubic bone. Three surfaces ( Anterior, Posterior and Medial surfaces ) A pubic tubercle at the lateral end of the pubic crest In the female, the pubis is anterior to the urethral sponge. The pubis is the lower limit of the suprapubic region. It is covered by a layer of fat – the mons pubis. The left and right coxal bones join at the pubic symphysis. The pubic bone is made up of a body, superior ramus, and inferior ramus ( Latin: branch). The left and right pubic bones are each made up of three sections, a superior ramus, inferior ramus, and a body. The pubis is the most forward-facing ( ventral and anterior) of the three bones that make up the hip bone. In vertebrates, the pubis or pubic bone ( Latin: os pubis) forms the lower and anterior part of each side of the hip bone.
