Quick Facts
Origin: Posterior femoral cutaneous nerve (S1—S3).
Course: After the posterior femoral cutaneous nerve passes through the greater sciatic foramen to enter the pelvic cavity, it gives off gluteal cutaneous branches.
Branches: None.
Supply: Sensory innervation to the skin over the inferior half of the buttock.

Origin
The inferior gluteal cutaneous nerves, or inferior cluneal nerves, are cutaneous branches of the posterior femoral cutaneous nerve.
Course
The posterior femoral cutaneous nerve passes through the greater sciatic foramen underneath the piriformis muscle, to enter the pelvic cavity. It descends underneath the gluteus maximus and fascia latae and gives off the inferior gluteal cutaneous nerves.
Branches
There are no named branches.
Supplied Structures
The inferior gluteal cutaneous nerves provide sensory innervation to the skin over the inferior half of the buttock.
