|The pectineus and nearby muscles|
|Structures passing behind the inguinal ligament. (Pectineus visible at bottom right.)|
|Gray's||subject #128 472|
|Origin:||Pubis - superior ramus|
|Insertion:||Lesser trochanter, linea aspera|
|Nerve:||Femoral nerve, sometimes obturator nerve|
|Action:||Thigh - flexion, adduction, medial rotation|
It is one of the muscles primarily responsible for hip flexion. It also adducts and medially rotates the thigh.
Origin and insertion
It arises from the pectineal line of the pubis and to a slight extent from the surface of bone in front of it, between the iliopectineal eminence and tubercle of the pubis, and from the fascia covering the anterior surface of the muscle; the fibers pass downward, backward, and lateralward, to be inserted into a the pectineal line of the femur which leads from the lesser trochanter to the linea aspera.
