Tensor fascia lata m
o i a |
o: proximal= ASIS(anterior superior iliac spine and anterior portion of iliac crest)
distal: iliotibial tract- inserts onto lateral condyle of the tibia Innervation: Superior Gluteal n (L4-S1) Action; Abducts, medially rotates, and flexes thigh, helps extend the knee |
|
Rectus Femoris,Vastus lateralis, Vastus medialis, Vastus intermedius,
o i a |
Origin
distal: base of patella and by patellar lig to tibial tuberosity Innervation: femoral N (L2-4) Action: Extend leg at knee jt; RF also helpps flex thigh |

|
Pectineus m
o i a |
O: proximal= superior ramus of pubis
Distal: pectineal line of femur innervation: femoral N (maybe obturator n) action: adducts and flexes thigh; assists w/med rotation of thigh |
|
Gracilis m
o i a |
o: proxmial: body and inf ramus of pubis
distal: sup pt. of med surface of tibia innervation: Obturator n action: adducts thigh, flexes and medially rotates leg |
|
Adductor longus m
o i a |
o: proximal- body of pubis inf. to pubis crest
distal: middle 1/3 of linea aspera innervation: Obturator N Action: adducts thigh |
|
Adductor brevis m
o i a |
Origin: proximal- body and inf. ramus of pubis
distal: pectineal line and prox. pt. of linea aspera innervation: obturator n action: adducts and flexes thigh |
|
Adductor magnus m (adductor pt)
o i a |
DUAL: adductor pt and hamstring pt
origin of adductor: prox- ramus of pubis, ramus of ischium distal" gluteal tuberosity, linea aspera med spracondylar line innervation: obturator n action: adducts thigh, flexes thigh |
|
Adductor magnus (hamstring pt)
o i a |
Origin proxmial: ischial tuberosity
distal: adductor tubercle of femur innervation: tibial n action: extends thigh |
|
obturator externus
o i a |
Origin proxmial- obturator foramen margins and obturator membrane
distal- trochanteric fossa of femur innervation: obturator n action: laterally rotates thigh, steadies head of femur. |
