Nerve To The Obturator Internus

The nerve to obturator internus is a branch of the sacral plexus. The sacral plexus is a network of nerves that arises from the ventral rami of the sacral spinal nerves. The sacral plexus is located in the pelvis, and it supplies nerves to the muscles and skin of the lower limbs. The nerve to obturator internus arises from the ventral rami of the L5, S1, and S2 nerve roots. The nerve then travels through the greater sciatic foramen inferior to the piriformis muscle. The nerve then pierces the obturator internus muscle and supplies it with motor innervation. The nerve to obturator internus also provides sensory innervation to the medial thigh.

Ventral rami of l4-s3 with parts of l4 and s4 spinal nerves form the sacral plexus. it is located on the posterior wall of pelvic cavity (pelvis minor). nervi of the plexus innervate the perineal region, buttocks and the lower limb. the largest nerve of the human body, the sciatic nerve, is the main branch that gives rami to the motor innervation of the muscles of the thigh, the leg, and the foot. common peroneal nerve and its branches innervate some parts of the skin of the foot, the peroneal muscles of the leg, and the dorsal muscles of the foot.
