The inferior gluteal nerve is the main motor nerve that innervates the gluteus maximus muscle.
Structure
The inferior gluteal nerve originates in the sacral plexus. It arises from the dorsal divisions of the fifth lumbar and first and second sacral nerves: it leaves the pelvis through the greater sciatic foramen, below the piriformis, and divides into branches which enter the deep surface of the gluteus maximus, the principal extensor of the thigh, and supply it.
it also gives off small branches to supply the deep gluteal muscles. [1] [2]
Function
This nerve is responsible for hip extension. When non-functional, it leads to difficulty in jumping, climbing stairs, and rising from a seated position. [1]
