pectineus muscle

An adductor muscle that attaches to the pelvic bone and the femur. In humans, The pectineus muscle is a flat, quadrangular muscle, situated at the anterior part of the upper and medial aspect of the thigh. It can be classified in the medial compartment of thigh (when the function is emphasized) or the anterior compartment of thigh (when the nerve is emphasized). [WP,generalized].
