Male external genitalia and perineum
Tela subcutanea; deep membranous layer of superficial fascia, anteroinferior view
The skin has been removed from the abdominal wall, the external genitalia and the perineum. The tela subcutanea has been dissected to expose the deeply placed membranous layer of superficial fascia which over the lower part of the abdominal wall is known as Scarpa's fascia (1) and over the penis, scrotum and perineum has been called Colles' fascia (19). In the scrotum this layer is blended into the tunica dartos.
