Male external genitalia and perineum
Contents of superficial perineal space
The deep perineal fascia has been cut away to reveal the bulbospongiosus and ischiocavernosus muscles. The crura of the penis (5) are partially visible as is the corpus spongiosum penis (14). The superficial transverse perineal muscles are poorly developed in this specimen but an example of the muscle may be be seen in view 174-1.
