View Yoshi Yu's current disclosuresThe 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.
Summary
origin: pectineal line (pecten pubis) of the pubic bone
insertion: pectineal line of the femur, an oblique line extending from base of the lesser trochanter to linea aspera on the posterior surface of the 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.
