Identify muscles and erectile tissues of the perineum.

1. Identify the perineal body (central tendon) intermediate between the penis and the anus. (G 5.50;N 373;Gl 22.25)
2. Identify the glans, body and bulb of the penis (G 5.51 and 5.55;N 359 and 360;Gl 21.28 and 21.29) and the bulbospongiosus muscle. (G 5.50;N 359;Gl 21.28)
3. Identify the ischiocavernosus muscle. (G 5.50;N 359;Gl 21.28)
4. On the side with the ischiocavernosus muscle removed, identify the crus of the penis. (G 5.51;N 360;Gl 21.28) On the same side (the bulbospongiosus muscle has been reflected), identify the bulb of the penis.
5. Identify the deep fascia of the penis. (G 5.56;N 360;Gl 22.24) Identify the deep dorsal vein, dorsal arteries and dorsal nerves of the penis. (G 5.54;N 359;Gl 22.24) Trace the deep dorsal vein, dorsal arteries and dorsal nerves to the pubic symphysis. Identify the paired corpora cavernosa and the unpaired corpus spongiosum of the penis.
