This section passes through the rectus abdominis muscles (42), suspensory ligament of the right ovary (5), uterus (40), ilium (9, 31), and sacrum (22).

On the left side, the peroneal (29) and tibial (27) divisions of the sciatic nerve are seen separated by the superior gluteal artery and vein in the sciatic foremen (28).

A portion of the broad ligament (30, 36) is seen covering the uterus (40). The uterine artery is seen on the right lateral surface of the uterus. The uterine cavity (33) is seen as a narrow slit in the thick body of the organ.

The pudendal nerves (20, 23) are seen near their origin from sacral nerves 2, 3, and 4. The pudendal nerve is variable and may arise from nerves S1 through S5, but usually from three nerves.
