The posterior cutaneous nerve of the thigh, also known as the posterior femoral cutaneous nerve, is a sensory nerve derived from the sacral plexus. It supplies the skin of the posterior thigh, buttock, posterior aspect of the scrotum/labia and a variable area of the posterior calf .

It arises partly from the dorsal divisions of the first and second, and from the ventral divisions of the second and third sacral nerves, 

It arises from the posterior divisions of the anterior rami of S1 and S2 nerves and the anterior divisions of anterior rami of S2 and S3 nerves.

Origin

The fibers contributing to the posterior cutaneous nerve of the thigh arise from posterior divisions of the anterior rami of the S1 and S2 nerves, and anterior divisions of the anterior rami of nerves S2 and S3.
