This section passes through the coccyx (28) and pubis (57). It cuts the femoral neck (14, 43), the edge of the greater trochanter (42), and the ischial tuberosities (35).

The proximal part of the penis and its blood supply (63) are seen. The pampiniform plexus of veins (5, 59) can be seen within the spermatic cords, which flank the proximal part of the penis. The prostatic plexus of veins (3) can be found adjacent to the dorsal veins of the penis (2).

The prostate (25) and the prostatic urethra (30) are shown. Note the pathologic enlargement on the left side and the abscess in the prostate gland (31).

The puborectalis muscle (26, 32), a part of levator and, forms a sling around the distal end of the digestive tube and marks the rectoanal junction.

The femoral artery and vein have branched, forming the first perforating artery and veins (11, 46). The deep femoral vein (49) can be seen joining the femoral vein (52).

Adductor brevis (60), adductor longus (56), adductor magnus (55), the tendon of origin of gracilis (3), vastus intermedius (45), and vastus lateralis (43) are seen for the first time. Gluteus medius muscle (16) is seen for the last time.

The pudendal blood vessels and nerve are seen in the pudendal canal (22, 33).

The inferior fascia of the pelvic diaphragm (23) and the rectal columns (of Morgagni) (29) can be identified.
