| dorsal nerve of clitoris | The deep terminal branch of the pudendal, supplying especially the glans clitoridis after passing through the musculature of the urogenital diaphragm, to run along the dorsum of the clitoral shaft. Synonym: nervus dorsalis clitoridis. (05 Mar 2000) |
| dorsal nerve of penis | The deep terminal branch of the pudendal which runs through the urogenital diaphragm giving branches, then runs along the dorsum of the penis, supplying the skin of the penis, the prepuce, the corpora cavernosa, and the glans.
