Structure/Morphology
The glans penis is an enlarged bulbous shaped erectile tissue, which is composed of the terminal portion of the corpus spongiosum.
Anatomical Relations
The glans penis is covered by a fold of skin called the prepuce. The external urethral meatus is an opening is the distal tip of the glans penis.
Function
The high concentration of sensory nerves in the glans penis indicates that stimulation of the glans penis contributes to maintaining an erection and initiating ejaculation.
Arterial Supply
The glans penis is supplied by the dorsal artery of the penis and the artery to the bulb of the penis. Both are branches from the perineal artery, which is a branch of the internal pudendal arteries.
Venous Drainage
The glans penis is drained by the deep dorsal vein of the penis, which drains into the prostatic venous plexus.
Innervation
The glans penis is very sensitive due to the high concentration of nerve endings in the glans penis. It is innervated by the dorsal nerve of the penis.
Lymphatic Drainage
The lymph of the glans penis is drained into the deep inguinal and external iliac lymph nodes.
