What nerve innervates the obturator externus?

Question

Quizplus · Accepted Answer

The obturator externus muscle is innervated by the obturator nerve, which arises from the lumbar plexus and runs down through the pelvis to provide motor and sensory innervation to the adductor muscles and the skin on the medial aspect of the thigh. The tibial nerve supplies the posterior compartment of the thigh, leg, and foot, while the L1 spinal nerve is one of the nerves that makes up the lumbar plexus. The nerve to the obturator internus, on the other hand, innervates the obturator internus muscle, which lies above the obturator externus and forms part of the pelvic floor.
