Deep branch of the perineal nerve

Deep branch of the perineal nerve
Nerve: Deep branch of the perineal nerve
Pudendal nerve, its course through the lesser sciatic foramen, and branches, including deep perineal nerve at bottom.
The superficial branches of the internal pudendal artery. (Deep branch of the perineal nerve visible but not labeled.)
From perineal nerve

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 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 [2]
