Nerve to Quadratus femoris and Inferior gemellus

Introduction The nerve to quadratus femoris and inferior gemellus is formed from the anterior or ventral divisions of the L4, L5, and S1 nerve roots of the sacral plexus. The nerve gives muscular branches to the quadratus femoris and inferior gemellus muscles as well as giving an articular branch to the hip joint. Gross anatomy…

Nerve to internal obturator and superior gemellus

Introduction The nerve to the obturator internus and superior gemellus is formed by the anterior (ventral) divisions of the L5, S1, and S2 nerve roots of the sacral plexus. The nerve innervates the obturator internus and superior gemellus muscles as well as the fascia of the lateral aspect wall of the ischioanal fossa. Gross anatomy…
