This section passes through the corpora cavernosa penis (59), the crura of the penis (3, 54), the membranous urethra (53), and the anus (27). The lesser trochanter of the femur (18) and the ischiorectal fossa (26) are seen in this cut.

The deep artery of the penis (58) and the dorsal veins of the penis (1) are identified.

The psoas major muscle (16, 44) inserts onto the lesser trochanter (18, 35), and the tendon of origin of semitendinosus and biceps femoris (long head) (34) is identified on the left ischial tuberosity (33).
