Perineal branches

The perineal branches of the posterior femoral cutaneous nerve (Latin: rami perineales nervi cutanei femoris posterioris) are small sensory branches of the posterior cutaneous nerve of the thigh that innervate the skin in the perineal region.

The perineal branches turn around the ischial tuberosity, reaching the perineal region.

The perineal branches of the posterior femoral cutaneous nerve supply the skin in the perineum region, and in the upper and medial side of the thigh.
