KINE 3135: The Hip Joint

The video tutorial provides a comprehensive overview of the hip joint, including its anatomy and function. It explains the movements of flexion, extension, abduction, and adduction, detailing the planes of motion involved. The tutorial also covers the muscles responsible for these movements, highlighting the roles of the quadriceps and hamstrings. Additionally, it discusses external and internal rotation of the hip, as well as diagonal movements. The video concludes with a brief mention of exercises that target specific hip muscles.

What is the function of the acetabulum in the hip joint?

• It is the main muscle responsible for hip flexion.

• It serves as the socket for the femoral head.

• It connects the two hemispheres of the pelvis.

• It is a ligament that stabilizes the hip joint.

Which plane of motion is involved in hip flexion?

• Sagittal plane

• Transverse plane

• Coronal plane

• Frontal plane

What is the primary difference between hip abduction and adduction?

• Both movements occur in the sagittal plane.

• Abduction moves the leg towards the midline, adduction moves it away.

• Both movements involve the same range of motion.

• Abduction moves the leg away from the midline, adduction moves it towards.

What is external rotation of the hip?

• Moving the leg backward in the frontal plane.

• Moving the leg forward in the sagittal plane.

• Rotating the leg so the foot points away from the midline.

• Rotating the leg so the foot points towards the midline.

Which muscle is NOT primarily involved in hip flexion?

• Gluteus maximus

• Rectus femoris

• Sartorius

• Iliacus

Which muscle group is primarily responsible for hip extension?

• Abductors

• Hamstrings

• Quadriceps

• Adductors

Which muscle is involved in both hip abduction and internal rotation?

• Adductor longus

• Gluteus medius

• Rectus femoris

• Bicep femoris

What is the role of the gluteus minimus in hip movement?

• It promotes hip internal rotation.

• It promotes hip external rotation.

• It promotes hip flexion.

• It promotes hip extension.

Which muscle is primarily responsible for hip adduction?

• Adductor magnus

• Gluteus maximus

• Tensor fascia lata

• Iliacus

Which exercise would primarily target the adductor muscles of the hip?

• Squats

• Leg press

• Adductor machine

• Abductor machine
