Tensor fasciae latae muscle (3D)

The video tutorial explores the tensor fascia lata muscle, detailing its anatomy, innervation, and functions. It highlights the muscle's role in stabilizing the pelvis, assisting in hip and knee movements, and its importance in everyday activities. The tutorial also explains the muscle's involvement in internal and external rotation, abduction, and stabilization of the knee joint, providing a comprehensive understanding of its functions.

What is the primary nerve that innervates the tensor fascia lata muscle?

• Inferior gluteal nerve

• Superior gluteal nerve

• Sciatic nerve

• Femoral nerve

Which two joints are primarily influenced by the tensor fascia lata muscle?

• Knee and elbow joints

• Hip and ankle joints

• Shoulder and hip joints

• Hip and knee joints

How does the tensor fascia lata muscle assist during the swing phase of walking?

• By internally rotating the femur

• By stabilizing the knee joint

• By externally rotating the femur

• By abducting the thigh

What role does the tensor fascia lata muscle play in stabilizing the pelvis?

• It abducts the contralateral hip

• It adducts the ipsilateral hip

• It abducts the ipsilateral hip

• It adducts the contralateral hip

At what degree of knee flexion does the tensor fascia lata muscle assist in knee extension?

• Less than 25 degrees

• More than 30 degrees

• Exactly 45 degrees

• Between 25 and 30 degrees

How does the tensor fascia lata muscle contribute to knee joint protection?

• By increasing knee flexion

• By preventing excessive internal rotation

• By promoting internal rotation

• By decreasing knee extension

What is the role of the iliotibial band in knee stabilization?

• It stabilizes the lateral aspect of the knee

• It decreases knee extension

• It supports the medial aspect of the knee

• It increases knee flexion
