The pectineus is a flat quadrangular muscle located at the anterior part of the upper medial aspect of the thigh. As it receives dual-innervation it can be classified as either within the medial compartment or the anterior compartment of the thigh.
- origin: pectineal line (pecten pubis) and adjacent bone of pelvis
- insertion: oblique line extending from base of lesser trochanter to linea aspera on posterior surface of femur
- action: adducts and flexes thigh at hip joint
- arterial supply: superficial part by medial circumflex femoral artery and deep part by the anterior branch of obturator artery
- innervation: femoral nerve anteriorly, a branch of obturator nerve, the accessory obturator nerve, to the smaller posterior part of the muscle.
