THIGH MUSCLES OBJECTIVE Recognize the thigh muscles & their functions The thigh muscles has primary function on the knee & secondary function on the hip joint THIGH MUSCLES The thigh muscles are grouped into 3 compartments: Anterior (knee Medial (hip Posterior (knee extensor) adductor) flexor) Quadriceps femoris & Adductors, pectineus, Hamstring muscles sartorius obturator externus & gracilis ANTERIOR COMPARTMENT Sartorius O: ASIS I: proximal medial tibia F(x): flex, abduct & lateral rotate hip, flex knee Rectus femoris O: AIIS V. lateralis O: greater trochanter, linea aspera V. medialis O: intertrochanteric line, linea aspera V. Intermedius O: femoral shaft *** I: tibial tuberosity *** F(x): extend knee, rectus femoris flex hip MEDIAL COMPARTMENT Obturator externus O: obturator foramen I: trochanteric fossa F(x): lateral rotate hip Pectineus O: superior pubic ramus I: pectineal line F(x): flex hip Gracilis O: inferior pubic ramus I: proximal medial tibia F(x): flex knee Adductors O: inferior pubic ramus I: linea aspera ***F(x): adducts thigh POSTERIOR COMPARTMENT Semitendinosus O: ischial tuberosity I: proximal tibial medial surface Semimembranosus O: ischial tuberosity I: tibial medial condyle Biceps femoris O: ischial tuberosity, linea aspera I: head of fibula F(x): extend hip, flex knee
