10. What are the movements of the quadratus femoris?

Abduction of thigh, flexion of leg at hip.

Flexion of thigh, extension of leg at hip.

Laterally rotate thigh, adduction of leg at hip

Medially rotate thigh, abduction of leg at hip.

The quadratus femoris muscle is responsible for laterally rotating the thigh and adducting the leg at the hip joint, not medially rotating or abducting. It is not involved in flexion movements of the thigh or extension movements of the leg at the hip.

Explanation

Submit

11. What are the attachments of the quadratus femoris?

External ischial tuberosity to superior portion of femur

From iliac crest to patella.

Between tibia and fibula.

Connects scapula to humerus.

The correct attachment of the quadratus femoris is from the external ischial tuberosity to the superior portion of the femur. The other options do not correctly describe the attachments of the quadratus femoris.

Explanation

12. What are the primary movements of the tensor fasciae latae muscle?

Flex and rotate at the shoulder.

Adduct and extend at the hip.

Abduct and flex at hip

Extend and rotate at the knee.

The tensor fasciae latae muscle primarily functions to abduct and flex at the hip joint, allowing for movements like lifting the leg sideways and bringing the thigh towards the chest.
