Key Features/ Anatomical Relations
Due to the smaller density of erectile tissue in the corpus spongiosum, the tunica albuginea is thinner in comparison to the thick tunica albuginea covering the corpus cavernosum.
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.
