The Inferior rectal nerves (inferior anal nerves, inferior hemorrhoidal nerve) usually branch from the pudendal nerve but occasionally arises directly from the sacral plexus; they cross the ischiorectal fossa along with the inferior hemorrhoidal vessels, toward the anal canal and the lower end of the rectum, and is distributed to the Sphincter ani externus and to the integument around the anus.

Branches of this nerve communicate with the perineal branch of the posterior femoral cutaneous and with the posterior scrotal nerves at the forepart of the perineum.

Supplies

Skin and external anal sphincter but doesn't supply the actual rectum

In the present study, we characterized the evoked electrical activity from T(13) to S(2) dorsal roots (DRs) during glass probe-stimulation of the vagina-cervix-uterus junction (VCUJ) of female Wistar rats. The results showed that gentle stimulation of VCUJ evoked high-amplitude electrical activity i
