Quizplus · Accepted Answer

The pubic and ischial rami are two parts of the hip bone that encircle the obturator foramen, a large opening in the bone that allows blood vessels and nerves to pass through. The other options are incorrect because:

A) The pubic symphysis is where the two pubic bones join together in the front of the pelvis.
B) The lesser sciatic notch is a small opening in the ischium bone that allows some blood vessels and nerves to pass through.
C) The greater sciatic notch is a large notch in the ilium bone that allows the sciatic nerve to pass through.
E) The acetabulum is a cup-shaped socket on the lateral surface of the hip bone that articulates with the head of the femur to form the hip joint.
