Anatomical terms of muscle

The pectineus muscle (/pɛkˈtɪniəs/, from the Latin word pecten, meaning comb)[1] is a flat, quadrangular muscle, situated at the anterior (front) part of the upper and medial (inner) aspect of the thigh. The pectineus muscle is the most anterior adductor of the hip. The muscle's primary action is hip flexion; it also produces adduction and internal rotation of the hip.

It can be classified in the medial compartment of thigh[2] (when the function is emphasized) or the anterior compartment of thigh (when the nerve is emphasized).[3]
