Pudendal nerve originates from which spinal segments?

Explanation:
Pudendal nerve fibers come from the sacral portion of the spinal cord, specifically the ventral rami of S2 to S4, forming part of the sacral plexus. This is why it supplies sensation to the perineal region and motor to several pelvic floor muscles. Roots from the cervical (C3-C5) or thoracic (T1-T4, T5-T12) levels do not contribute to this nerve, so they’re not correct origins. The standard origin is S2 through S4.
