Rotator Cuff

What are the four muscles that make up the rotator cuff?

• Gluteus maximus, Hamstrings, Quadriceps, Gastrocnemius

• Latissimus dorsi, Trapezius, Rhomboids, Serratus anterior

• Supraspinatus, Infraspinatus, Teres minor, Subscapularis

• Biceps brachii, Triceps brachii, Deltoid, Pectoralis major

Which muscle of the rotator cuff is responsible for internal rotation of the shoulder?

• Pectoralis major

• Subscapularis

• Deltoid

• Teres minor

What is the function of the supraspinatus muscle in the rotator cuff?

• Initiate abduction and stabilize the shoulder joint

• Adduct the shoulder and stabilize the elbow

• Extend the shoulder and rotate the arm

• Flex the elbow and stabilize the wrist

Where is the subscapularis muscle located in the rotator cuff?

• Posterior aspect of the femur

• Lateral aspect of the tibia

• Superior aspect of the humerus

• Anterior aspect of the scapula

What is the role of the infraspinatus muscle in the rotator cuff?

• Flexion and extension of the elbow

• Adduction and abduction of the shoulder joint

• Internal rotation and stabilization of the shoulder joint

• External rotation and stabilization of the shoulder joint

What type of joint is the shoulder joint where the rotator cuff is located?

• Pivot joint

• Ball-and-socket joint

• Hinge joint

• Gliding joint

What is the main function of the rotator cuff as a whole?

• Digest food in the stomach

• Regulate blood pressure

• Control breathing

• Stabilize and move the shoulder joint

What is the significance of the rotator cuff in shoulder stability?

• It is only important for elbow stability

• It helps stabilize the shoulder joint and allows for a wide range of motion.

• It only allows for limited range of motion

• It has no impact on shoulder stability

What are the common injuries that can affect the rotator cuff?

• Concussions, ACL tears, and plantar fasciitis

• Fractures, dislocations, and sprains

• Tendonitis, bursitis, and tears

• Carpal tunnel syndrome, tennis elbow, and shin splints

How does the anatomy of the rotator cuff contribute to the range of motion of the shoulder joint?

• The rotator cuff muscles and tendons have no impact on the range of motion of the shoulder joint

• The rotator cuff muscles and tendons contribute to the range of motion of the shoulder joint by providing stability and allowing for smooth movement.

• The rotator cuff restricts the range of motion of the shoulder joint

• The rotator cuff is not connected to the shoulder joint
