ANTERIOR FASCIAL COMPARTMENT OF THIGH Flashcards
O: anterior surface iliac spine
I: upper medial surface of shaft of tibia
N: femoral nerve
A: flexes, abducts, laterally rotates thigh at hip joint; flexes and medially rotates leg at knee joint
Sartorius
O: iliac fossa of hip bone
I: with psoas into lesser trochanter of femur
N: femoral nerve
A: flexes thigh on trunk; if thigh is fixed, it flexes the trunk on the thigh as in sitting up from lying down
Iliacus
O: transverse processes, bodies, and intervertebral discs of 12th thoracic and 5 lumbar vertebrae
I: with iliacus into lesser trochanter of femur
N: lumbar plexus
A: flexes thigh on trunk: if thigh is fixed, it flexes trunk on thigh as in sitting up from lying down
Psoas
O: superior ramus of pubis
I: upper end of linea aspera of shaft of femur
N: femoral nerve
A: flexes and adducts thigh at hip joint
Pectineus
O: lateral border of ischial tuberosity
I: quadrate tubercle of femur
N: sacral plexus
A: lateral rotator of thigh at hip joint
Quadratus Femoris
O: STRAIGHT HEAD - anterior inferior iliac spine
REFLECTED HEAD - ilium above acetabulum
I: quadriceps tendon into patella, then via ligamentum patellae into tubercle of tibia
N: femoral nerve
A: extension of leg at knee joint; flexes thigh at hip joint
Rectus Femoris
O: upper end and shaft of femur
I: quadriceps tendon into patella, then via ligamentum patellae into tubercle of tibia
N: femoral nerve
A: extension of leg at knee joint
Vastus Lateralis
O: upper end and shaft of femur
I: quadriceps tendon into patella, then via ligamentum patellae into tubercle of tibia
N: femoral nerve
A: extension of leg at knee joint; stabilizes patella
Vastus Medialis
O: anterior and lateral surfaces of shaft of femur
I: quadriceps tendon into patella; then via ligamentum patellae into tubercle of tibia
N: femoral nerve
A: extension of leg at knee joint; articularis genus retracts synovial membrane
Vastus Intermedius
