Which Group of Muscles Moves the Arm at the Shoulder

Question

Which group of muscles moves the arm at the shoulder?
A) Quadriceps femoris group
B) Hamstrings
C) Rotator cuff muscles
D) Muscles of mastication

Accepted Answer

The group of muscles that move the arm at the shoulder are called the rotator cuff muscles. The four muscles that make up the rotator cuff are the supraspinatus, infraspinatus, teres minor, and subscapularis. These muscles work together to stabilize and move the shoulder joint, allowing for a wide range of movements including lifting, reaching, and rotating the arm.
