Posterior Branch Of Obturator

The posterior division of the obturator nerve is a branch of the obturator nerve. It arises from the obturator nerve in the obturator canal. The posterior division of the obturator nerve supplies motor innervation to the obturator externus muscle and the adductor magnus muscle. The posterior division of the obturator nerve also provides sensory innervation to the skin of the medial thigh. The posterior division of the obturator nerve is a relatively small nerve, but it is an important nerve that supplies nerves to the muscles and skin of the medial thigh.

Obturator

Since the lumbar plexus and sacral plexus are interconnected, they are sometimes referred to as the lumbosacral plexus. the intercostal nerves that give rami to the chest and to the upper parts of the abdominal wall efferent motor innervation and to the pleura and peritoneum afferent sensory innervation are the only ones that do not originate from a plexus. the ventral rami of l1-l5 spinal nerves with a contribution of t12 form lumbar plexus. this plexus lies within the psoas major muscle. nervi of the plexus serve the skin and the muscles of the lower abdominal wall, the thigh and external genitals. the largest nerve of the plexus is the femoral nerve. it supplies anterior muscles of the thigh and a part of skin distal to the inguinal ligament.
