pu·den·dal nerve

[TA]

branch of the sacral plexus formed by fibers from the ventral primary rami of the second, third, and fourth sacral spinal nerves; it exits the pelvis via the greater sciatic foramen, passes posterior to the sacrospinous ligament, and accompanies the internal pudendal artery, into the perineum via the lesser sciatic foramen; it gives off inferior rectal nerves, then courses through the pudendal canal in the lateral wall of the ischiorectal fossa, terminating as the dorsal nerve of the penis or of the clitoris.

Synonym(s): nervus pudendus [TA], plexus pudendus nervosus, pudic nerve
