Inferior anal nerves
Latin  Nervi anales inferiores, nervi rectales inferiores, nervus haemorrhoidalis inferior

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 (external anal sphincter, EAS) and to the integument (skin) 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

Cutaneous innervation below the pectinate line and external anal sphincter.
