The deep branch of the perineal nerve (or muscular branches) are distributed to the muscles of the perineum.[1] These include the superficial transverse perineal muscle, bulbospongiosus, ischiocavernosus, and Sphincter 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.
The dorsal nerve of the penis for males and the dorsal nerve of the clitoris for females is the terminal branch of the pudendal nerve.
