Musculus gluteus maximus

The video tutorial provides an in-depth look at the gluteus maximus muscle, highlighting its superficial nature and significant role in shaping the region. It details the muscle's origin points, including the OS sacrum and OS ilium, and its attachment to the iliotibial tract and tibia. The tutorial explains the nerve supply from the sacral plexus and the associated blood vessels. It also covers the muscle's primary functions as an extensor and external rotator, its role in stabilizing the hip joint, and the antagonistic tasks of its fiber groups.

Which bone is referred to as OS sacrum in Latin?

• Femur

• Ilium

• Tibia

• Sacrum

What is the primary nerve controlling the gluteus maximus?

• Sciatic nerve

• Inferior gluteal nerve

• Pudendal nerve

• Superior gluteal nerve

Which structure does the cranial fibers of the gluteus maximus radiate into?

• Femoral tract

• Sacral tract

• Tibial tract

• Iliotibial tract

What is the main function of the gluteus maximus muscle?

• Internal rotation of the hip

• Extension and external rotation of the hip

• Flexion of the hip

• Abduction of the hip

How does the gluteus maximus help in stabilizing the hip joint?

• By enhancing flexion

• By reducing varus stress

• By promoting internal rotation

• By increasing varus stress
