Sartorius
From WikiSM
Origin
- Anterior superior iliac spine of the pelvis
Insertion
- Superior medial aspect of the tibial shaft
- Forms the Pes Anserinus with the Gracilis and Semitendinosus
Actions
- Hip flexion and external rotation
- Works synergistically with the Iliopsoas, Rectus Femoris, Tensor Fascia Lata, Pectineus, Adductor Longus, Adductor Brevis, and Gracilis to perform hip flexion
- Knee flexion and internal rotation
- Works synergistically with the Biceps Femoris, Semitendinosus, and Semimembranosus to perform knee flexion
- Works synergistically with the Pectineus to perform internal rotation
Artery
- Branches of the femoral artery
- Collateral blood flow from the superficial circumflex iliac artery, lateral circumflex femoral artery, superficial femoral artery, descending genicular artery, and superior medial genicular artery [1]
Nerve
- Anterior division of the Femoral Nerve from the L2, L3, and L4 nerve roots
Clinical Significance
- Pathology
- Anterior Superior Iliac Spine (ASIS) Avulsion
- Chronic Overuse Injury
