Anatomical terms of neuroanatomy

The dorsal nerve of the penis is the deepest of three divisions of the

inferior ramus of the pubis, between the superior and inferior layers of the fascia of the urogenital diaphragm
.

Piercing the inferior layer it gives a branch to the

suspensory ligament, on to the dorsum of the penis, and ends on the glans penis.[1]

It innervates the skin of the penis. In humans, it has 8290 ± 2553 axons, in 25–45 loosely packed nerve bundles, half of which are myelinated. The researches were conducted on volunteers that donated tissues after death, therefore some of the nerve endings could not have been counted due to the natural degeneration of tissues found in old people.[1]
