All the following muscles are supplied by Anterior division of Obturator Nerve except

The main nerve supply to muscles of the adductor compament is the obturator nerve. The adductor longus and the gracilis are supplied by the anterior division of this nerve. The adductor brevis is supplied by the anterior division or by the posterior division. The adductor magnus has a double nerve supply. Its adductor pa is supplied by the posterior division of the obturator nerve; while its hamstring pa is supplied by the tibial pa of the sciatic nerve. The pectineus muscle is of double origin so it also has a double innervation: its anterior fibers are supplied by the femoral nerve and its posterior fibers by the anterior division of the obturator nerve. Such muscles are called the hybrid or composite muscles.Reference: Chaurasia Volume II; 7th edition; Page no: 66
