Triceps
Your shoulder joint allows you to raise your arm above your head.
The supraspinatus muscle is one of the key muscles involved in a lateral raise. It is responsible for initiating the movement by abducting the arm away from the body. It works in conjunction with other shoulder muscles to raise the arm to the side.
Several muscles are used. Biceps brachii for elbow flexion, triceps brachii for elbow extension. Trapezius to raise arm. Deltoid abducts the arm. The pectoralis major allows internal rotation, adduction, and flexion of the arm. The pronator quadratus, pronator teres and supinator all arm forearm muscles that move the wrist. The brachioradialis, brachialis and aconeus are also used.

The Blue one
The ball-and-socket joint of the shoulder allows the upper arm to be raised and lowered.
The muscular system is responsible for actually moving the arm up, while the nervous system coordinates the activation of the muscles to raise the arm in response to your conscious thought or instruction from the brain.
Abduction of the arm is caused by contraction of the deltoid and supraspinatus muscles, which pull the arm away from the body. This movement allows for raising the arm to the side and is important for various shoulder and arm activities. Injuries or neurological conditions affecting these muscles or their nerve supply can lead to difficulty with arm abduction.
Raising and lowering your arm requires the coordination of multiple muscles. The primary muscles involved in this action include the deltoid, biceps, triceps, and various muscles of the shoulder and upper back. These muscles work together to perform the movement smoothly and efficiently.
The muscles of the arm are natural tighteners to the skin of the arm
