Where is pubis

The pubic bone is divisible into a body, a superior ramus, and an inferior ramus. Body of pubic bone : 1 sacrum, 2 ilium, 3 ischium, 4 pubis: 4a-body; 4b-superior ramus; 4c-inferior ramus, 5 pubic symphisis, 6 acetabulum, 7 obturator foramen, 8 coccyx, red dotted line linea terminalis.

The body of the pubis is a wide, strong, medial, and flat portion of the pubic bone that unites with the pubic symphisis. The rough superior edge of the corpus, known as 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 and is useful when attempting to localize 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 of the obturator internus muscle. It is made up of five fused vertebral bones. The sacrum is connected to the tailbone, or coccyx , which is made of several fused vertebral bones at the base of the spine. This is so a baby can pass through the pubic outlet, the circular hole in the middle of the pelvic bones, during childbirth.

The pubic arch, or space under the base of the pelvis, is also wider for this reason. The opening at the base of the pelvis, the obturator foramen, creates the ball-and-socket hip joint with the femur, the large bone of the leg. This joint and its ability to rotate in many angles is one of many pieces of anatomy that allows humans to walk. The spine, or vertebral column , is a tower of bone that consists of 24 irregular-shaped bones along with the nine fused bones in the sacrum and coccyx.

The lumbar vertebrae are the largest movable bones of the backbone. Pelvic fractures. A pelvic fracture requires considerable force. Although the fracture itself can heal on its own, pelvic fractures may be accompanied by damage to abdominal organs that require surgery.

Most pelvic fractures are caused by direct blows or by a blow through the thighbone femur. The pubic tubercle, crest and symphyseal surface may have separate centers. Anatomy: Abdominopelvic. Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys.
