b. Infraspinatus
c. Teres Major
d. Teres Minor

Answered by admin @ 27/09/2021

Answer:

The correct option is : c. Teres Major

Rotator cuff muscle is the group of muscles and their tendons present in the shoulder. The function of rotator cuff muscle is to stabilize the shoulder, by keeping the ball of the humerus bone in the socket of the shoulder.

The four rotator cuff muscles and their functions-

Supraspinatus muscle: abduction of humerus
Infraspinatus muscle: external rotation of humerus
Teres minor muscle: external rotation of humerus
Subscapularis muscle: internal rotation of humerus

Therefore, the rotator cuff muscle does not contain the teres major muscle.
