Key Features/ Anatomical Relations
The thick layer of tunica albuginea envelops the corpora cavernosa of the penis.
Function
The elastic nature of the tunica albuginea allows blood to flow easily through the dorsal arteries of the penis to initiate an erection. The deep fascia of the penis is less elastic and puts pressure on the dorsal vein of the penis nearer the root to prevent blood from leaving the penis.
