Corpus: Inferior rectal nerve

The inferior rectal nerves are terminal branches of the pudendal nerve that provide motor innervation to the external anal sphincter muscle and sensory innervation to the skin around the anus.

The inferior rectal nerves, accompanied by the inferior rectal artery and its veins, pass through the ischiorectal fossa and travel to the anal canal. These nerves supply motor function to the external anal sphincter and sensory function to the skin below the dentate line.

Damage or lesions to the inferior rectal nerves can result in faecal incontinence.
