Gluteus minimus muscle (3D)

The video tutorial explores the anatomy and functions of the gluteus minimus muscle, a key player in pelvic stabilization and movement. It begins with an introduction to pelvic tilt and the role of the gluteus minimus, followed by a detailed look at its anatomy. The tutorial then delves into the muscle's functions, including thigh abduction, internal rotation, and pelvic stabilization during gait. The importance of these functions is highlighted, especially in preventing conditions like Trendelenburg gait. The tutorial concludes with a recap of the muscle's roles.

What is the primary focus of the tutorial regarding the pelvic tilt?

• The anatomy of the femur

• The structure of the sacral plexus

• The role of the gluteus maximus

• The function of the gluteus minimus

Where does the gluteus minimus originate?

• From the posterior divisions of spinal nerves

• From the sacral plexus

• From the anterior and inferior gluteal lines of the ilium

• From the greater trochanter of the femur

Which nerve innervates the gluteus minimus?

• Inferior gluteal nerve

• Sciatic nerve

• Superior gluteal nerve

• Femoral nerve

What is one of the primary functions of the gluteus minimus?

• Extension of the knee

• Abduction of the thigh

• Flexion of the hip

• Rotation of the ankle

How does the gluteus minimus contribute to internal rotation of the thigh?

• By contracting its posterior fibers

• By working with the gluteus maximus

• By contracting its anterior fibers

• By stabilizing the knee joint

What condition is associated with a weak gluteus minimus?

• Trendelenburg gait

• Sciatica

• Plantar fasciitis

• Hip dysplasia

What is the role of the gluteus minimus in pelvic stabilization?

• It extends the knee joint

• It stabilizes the pelvis during the gait cycle

• It rotates the ankle

• It helps in flexing the hip joint
