Inferior Rectal (Hemorrhoidal) Nerve
Abstract
This nerve arises from S3, S4, and occasionally S2. It may arise from the sacral plexus directly rather than being one of the three terminal branches (inferior rectal, perineal, and dorsal nerve of the clitoris or penis) of the pudendal. The inferior rectal nerve may pierce the sacrospinous ligament medial to the ischial spine as reported in 20% of body halves. The inferior rectal nerve may arise in common with the perineal nerve.
