Anatomical terms of neuroanatomy] |
The perineal nerve is a
deep branch to muscles. It supplies the skin and muscles of the perineum. Its latency is tested with electrodes
.
Structure
The perineal nerve is a branch of the
deep branch of the perineal nerve (also known as the "muscular" branch) travels to the muscles of the perineum.[1] Both of these are superficial to the dorsal nerve of the penis or the dorsal nerve of the clitoris.[4]
Function
The perineal nerve supplies the skin and muscles of the
superficial transverse perineal muscle, the bulbospongiosus muscle, the ischiocavernosus muscle, the bulb of penis, levator ani, and the external anal sphincter.[1]
Clinical significance
The latency of the perineal nerve can be measured with electrodes.[5] It is used to test nerve function.[5]
