Pudendal nerve 阴部神经

Image showing the greater sciatic foramen (large foramen), and the lesser sciatic foramen, separated by the sacrospinous ligament. The pudendal nerve exits the pelvis through the greater sciatic foramen, passes over the ligament, and then reenters the pelvis through the lesser sciatic foramen.

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 the motor supply to various pelvic muscles, including the male or female external urethral sphincter and the external anal sphincter. If damaged, most commonly by childbirth, lesions may cause sensory loss or fecal incontinence. The nerve may also be temporarily blocked as part of an anaesthetic procedure.
