What is the origin and insertion of the Vastus Lateralis?
|
Origin: Anterior and inferior border of the greater trochanter, lateral region of the gluteal tuberosity, lateral lip of the linea aspera of the femur.
Insertion: Base of patella and tibial tuberosity of the tibia. |
|
What is the isolated function of the Vastus Lateralis?
|
Concentrically accelerates knee extension.
|
|
What is the integrated function of the Vastus Lateralis?
|
*Eccentrically decelerates knee flexion, adduction, and internal rotation.
*Isometrically stabilizes the knee. |
|
What is the origin and insertion of the Vastus Medialis?
|
Origin: Lower region of intertrochanteric line, medial lip of linea aspera, proximal medial supracondylar line of the femur.
Insertion: Base of patella, tibial tuberosity of the tibia. |
|
What is the isolated function of the Vastus Medialis?
|

|
What is the origin and insertion of the Rectus Femoris?
|
Origin: Anterior-inferior iliac spine of the pelvis.
Insertion: Base of the patella, tibial tuberosity of the tibia. |
|
What is the isolated function of the Rectus Femoris?
|
Concentrically accelerates knee extension and hip flexion.
|
|
What is the integrated function of the Rectus Femoris?
|
*Eccentrically decelerates knee flexion, adduction, and internal rotation.
*Decelerates hip extension. *Isometrically stabilizes the lumbo-pelvic-hip complex and knee. |
