Quadriceps

Question 1

Origin and Insertion of Vastus Laterlis

Answer 1

Origin: Anterior and inferior border of the great trochanter, lateral region of the gluteal tuberosity, lateral line of the linea aspera of the femus Insertion: Base of the patella

Question 2

Isolated and Integrated Function of Vastus Laterlis

Answer 2

Isolated Function: Concentrically accelerate knee extension Integrated Function: Eccentrically declerate the knee flexion, adduction, and internal rotation. Isometrically stabilizes the knee

Question 3

Origin and Insertion of Vastus Medialus

Answer 3

Origin: Lower region of the intertrochanteric line, medial lip of the linea aspera, proximal medial supracondylar line of the femur Insertion: base of the patella, tibial tuberosity of the tibia

Question 4

Isolated and Integrated Function of Vastus Medialus

Answer 4

Isolated Function: Concentrically accelerates knee extension Integrated Function: Eccentrically decelerates knee flexion, adduction, internal rotation. Isometrically stabilizes the knee

Question 5

Origin and Insertion of Vastus Intermedius

Answer 5

Origin: Anterior-lateral regions of the upper two thirds of the femur Insertion: base of the patella, tibial tuberosity of the tibia

Question 6

Isolated and Integrated Function of Vastus Intermedius

Answer 6

Isolated Function: Concentrically accelerates knee extension Integrated Function: Eccentrically decelerates knee flexion, adduction, internal rotation. Isometrically stabilizes the knee

Question 7

Origin and Insertion of Rectus Femoris

Answer 7

Origin: Anterior-inferior iliac spine of the pelvis Insertion: Base of the patella, tibial tuberosity of the tibia

Question 8

Isolated and Integrated Function of Rectus Femoris

Answer 8

Isolated Function: Concentrically accelerates knee extension and hip flexion Integrated Function: Eccentrically decelerates knee flexion, adduction, internal rotation. Decelerates hip extension. Isometrically stabilizes the knee
