Pectineus muscle

The pectineus muscle is a short muscle of the hip that connects the pelvis to the femur. Because of the angle the pectineus attaches at, it serves to flex, adduct and Medial|medially rotate the hip with a single motion.

Origin
The pectineus originates at the pectineal line of pubis bone on the pelvis.

Insertion
The pectineus inserts on the femur, below the lesser trochanter, along a verticle line between the spiral line and gluteal crest.

Innervation
The pectineus is innervated by the anterior division of femoral nerve (L2 and L3).

Word origin
The word pectineus comes from the Latin pecten, meaning comb.
