Anatomy & Physiology: Muscles—Pectineus.

Structure.

  • Origin: pectineal line on the superior pubic ramus of pelvis.
  • Insertion: pectineal line on the posterior surface of the upper femur.

Function.

  • Concentric action: accelerates hip adduction, medial rotation.
  • Reverse mover action: anterior tilt pelvis; ipsilateral rotation of pelvis.
  • Eccentric action: controls/restrains/decelerates hip abduction, lateral rotation.
  • Isometric action: stabilization of lumbo-pelvic hip complex.
  • Innervation: femoral nerve.
  • Arterial supply: femoral artery, deep femoral artery obturator artery.

Clinical Significance.
