Hip joint structure and actions

The video tutorial provides an in-depth look at the hip joint, a synovial ball and socket joint. It covers the anatomy, including the acetabulum and femur, and explains the role of the joint capsule, labrum, and ligaments in providing stability. The tutorial also details the movements of the hip joint, such as flexion, extension, abduction, adduction, and rotation, and the muscles involved in these movements.

What type of joint is the hip joint?

• Pivot joint

• Ball and socket joint

• Hinge joint

• Saddle joint

Which component of the hip joint increases its stability by deepening the socket?

• Articular cartilage

• Joint capsule

• Acetabular labrum

• Synovial fluid

Which ligament is NOT involved in stabilizing the hip joint?

• Pubofemoral ligament

• Ischiofemoral ligament

• Anterior cruciate ligament

• Iliofemoral ligament

What happens to the capsular ligaments when the hip joint is extended?

• They stretch and allow more movement

• They remain unchanged

• They tighten and draw the femur closer to the acetabulum

• They become loose

Which muscle is primarily responsible for flexing the hip?

• Gluteus maximus

• Hamstrings

• Adductor longus

• Iliopsoas

What is the primary function of the gluteus medius and minimus muscles?

• Adduction of the hip

• Abduction of the hip

• Extension of the hip

• Flexion of the hip

Which movement involves pivoting the femur outward?

• Internal rotation

• External rotation

• Flexion

• Adduction
