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
Pyramidal process of palatine bone articulation with the tuberosity of the maxilla; its posterior part consists of a smooth triangular area which appears, in the articulated skull, between the tuberosity of the maxilla and the lower part of the lateral pterygoid plate, and completes the lower part of the infratemporal fossa. On the base of the pyramidal process, close to its union with the horizontal part, are the lesser palatine foramina for the transmission of the posterior and middle palatine nerves. Pyramidal process of palatine bone The pyramidal process of the palatine bone projects backward and lateralward from the junction of the horizontal and vertical
