Deep branch of the perineal nerve
Encyclopedia
The deep branch of the perineal nerve (or muscular branches) are distributed to the muscles of the perineum
. These include the superficial transverse perineal muscle, bulbospongiosus, ischiocavernosus, and constrictor urethræ.
A branch, the nerve to the bulb, given off from the nerve to the bulbocavernosus, pierces this muscle, and supplies the corpus cavernosum
, ending in the mucous membrane of the urethra
.
It later becomes the dorsal nerve of penis
