Gluteal muscles

The video tutorial covers the anatomy and function of the gluteal muscles, including the gluteus maximus, medius, minimus, and tensor fascia lata. It explains their primary actions, such as hip extension and stabilization, and their innervation by the superior and inferior gluteal nerves. The tutorial also describes how to clinically test the superior gluteal nerve using the Trendelenburg sign.

Which muscle is the largest among the gluteal muscles?

• Tensor fascia lata

• Gluteus medius

• Gluteus minimus

• Gluteus maximus

What is the primary action of the gluteus medius when the hip is in a flexed position?

• Hip flexion

• Hip extension

• Hip adduction

• Hip rotation

Which muscle group is responsible for stabilizing the pelvis when one leg is lifted?

• Gluteus maximus

• Quadriceps

• Gluteus medius and minimus

• Tensor fascia lata

From which spinal cord levels does the superior gluteal nerve originate?

• L4 to S1

• L5 to S2

• L3 to L5

• S1 to S3

Which nerve innervates the gluteus maximus?

• Femoral nerve

• Sciatic nerve

• Inferior gluteal nerve

• Superior gluteal nerve

What is the Trendelenburg sign an indication of?

• Inferior gluteal nerve injury

• Superior gluteal nerve injury

• Femoral nerve injury

• Sciatic nerve injury

What action is performed by the gluteus maximus when the hip is flexed?

• Hip abduction
