Thigh Muscles Flashcards
Anterior Thigh muscles
Quads, Sartorius, articularis genu
Rectus femoris O and I
O: AIIS (straight tendon) and groove above acetabulum
I: base of patella
Rectus femoris function
knee extension and hip flexion
Anterior compartment N and Artery
Femoral N, femoral A
Vastus lateralis O and I
O: lateral lip of linea aspera, lateral lip of gluteal tuberosity, anterior and inferior boarders of greater trochanter, proximal intertrochanteric line
I: lateral border of patella
Vastus medialis O and I
O: medial lip of linea aspera, tendon of adductor longus/magnus, medial IM septum, proximal suprachondylar line, distal intertrochanteric line
I: medial border of patella
Vastus Intermedius O and I
O: proximal 2/3 of anterior and lateral surface of femur
I: base of patella
Sartorius O and I and function
O: ASIS
I: medial tibia (part of pos anserinus)
F: hackisack motion
Articularis genu O, I and function
O: anterior surface of distal femur
I: synovial membrane and supra patellar bursa
F: draws synovium proximally during knee flexion
Medial Compartment Muscles
gracilis, obturator externus, pectineus, adductor brevis, adductor longus, adductor magnus
Medial compartment A and N
A: medial circumflex, profunda femoris, obturator arteries
N: Obturator N
Gracilis O and I
O: inferior 1/2 of pubic symphysis, pubic body, superior 1/2 of inferior pubic rams
I: medial tibia (pes anserinus)
Gracilis Function
thigh adduction and medial rotation, knee flexion
Obturator externus O and I
O: external aspect of ischial and pubic rami, along margins of obturator foramen
I: trochanteric fossa
Pectineus O and I
O: pectin pubis and bone anterior to pectin pubis between pubic tubercle and iliopectineal line
I: Pectineal line of femur
