Dissection of female pelvis froma lateral approach
Pelvic diaphragm, lateral view with pudendal vessels and nerves in situ
In an earlier view of this specimen (158-7) the pelvic diaphragm was partially visible through a window cut in the lateral pelvic wall. The exposure of the diaphragm has been increased by resection of more of the ischium. The pudendal vessels and nerves have been retained in place, although the fascia (25) that formed the walls of the pudendal canal has been nearly completely removed from around them.
