This section passes through the penis (1), spermatic cords (2, 52), the corpus spongiosum (55) and bulbocavernosus muscle (51), the superficial transverse perineal muscle (30), the anal crease (27), and the anococcygeal ligament (28).

The pudendal plexus of veins (53) and pampiniform plexus (2, 52) are seen. The internal (24) and external (25) anal sphincters are identified.

The ischium (32) makes its last appearance in this section.

The femoral nerve is now seen divided into several branches (10, 46), which will supply, among others, the rectus femoris (9), sartorius (7), vastus intermedius (43), vastus medialis (42), and vastus lateralis (41).
