Document Summary

The abdominal muscles run from the ribcage to the pelvis and fill the anterior wall of the abdominal cavity. The bony pelvis or pelvic girdle consists of the paired hip bones. The hip bones are also called coxal bone or left and right innominate bones. The hip bones, sacrum, and coccyx form the pelvis. The hip bone consists of three fused bones the ilium, ischium, and pelvis. Where these three bones meet is the acetabulum, and it receives the ball-shaped head of the femur. The anterior superior iliac spine (asis) is the most anterior edge of the iliac crest. The inguinal ligament runs from asis down to the pubic tubercle. The ischial tuberosity is the site of attachment of groin muscles (sitting on them). The pubic symphysis is where the two innominate bones come together at the midline (anterior side). In a lateral view, the asis and pubic tubercle are in the same coronal plane.
