The dorsal nerve of the clitoris is a
nerve
A nerve is an enclosed, cable-like bundle of nerve fibers (called axons) in the peripheral nervous system.
A nerve transmits electrical impulses. It is the basic unit of the peripheral nervous system. A nerve provides a common pathway for the e ...

pudendal nerve
The pudendal nerve is the main nerve of the perineum. It carries sensation from the external genitalia of both sexes and the skin around the anus and perineum, as well as the motor supply to various pelvic muscles, including the male or fem ...

clitoris
The clitoris ( or ) is a female sex organ present in mammals, ostriches and a limited number of other animals. In humans, the visible portion – the glans – is at the front junction of the labia minora (inner lips), above the ope ...

inferior pubic ramus
In vertebrates, the pubic region ( la, pubis) is the most forward-facing (ventral and anterior) of the three main regions making up the coxal bone. The left and right pubic regions are each made up of three sections, a superior ramus, inferior r ...

suspensory ligament of the clitoris
The suspensory ligament of the clitoris is a fibrous band at the deep fascial level that extends from the pubic symphysis to the deep fascia of the clitoris, anchoring the clitoris to the pubic symphysis. By virtue of this connection, the pubic s ...
. At its thickest, the DNC is in diameter, visible to the naked eye during dissection.
[ The DNC splits into two nerve branches on either side of the midline, closely following the crura of the clitoris.][
Some surgeries—for example, sling surgeries to treat female urinary incontinence—can damage the DNC, causing a loss of sensation in the clitoris. Understanding the nerve is important for urologists and gynecologists who may operate on organs near the DNC.][
The dorsal nerve of the clitoris is analogous to the ]dorsal nerve of the penis
The dorsal nerve of the penis is the deepest division of the pudendal nerve; it accompanies the internal pudendal artery along the ramus of the ischium; it then runs forward along the margin of the inferior ramus of the pubis, between the superio ...
