Document Summary

O: posterior gluteal line on ilium, dorsal surface of sacrum. A: abduct thigh, medial rotation, holds pelvis level during swing phase of during weight bearing. A: lateral rotation of hip: sciatic nerve here. A: strong hip flexion: combination of iliacus and psoas muscles. A: flexion of knee, flexion of hip, lateral rotation of hip. Quadriceps group: 3 vastus + 3 rectus fe(cid:373)oris to , quadriceps te(cid:374)do(cid:374) to , patella to , patellar liga(cid:373)e(cid:374)t to , tibial tuberosity. O: add: inferior ramus of pubis; hamstring: ischial tuberosity. In: add: gluteal tuberosity and linea aspera; hamstring: adductor tubercle of femur. N: add: obturator nerve; hamstring: tibial division of sciatic nerve. A: add: adducts thigh and some flexion; hamstring: extend thigh at hip joint. Pes anserinus: sartorius, gracilis and semitendinosus make a conjoined tendon. Muscles: sartorius, rectus femoris, vastus lateralis, vastus intermedius, vastus medialis. Main action: extend knee, hip flexion (sart + recfem, knee flexion (sart)
