During elbow flexion, the primary muscles involved are the biceps brachii and brachialis. The rotator cuff plays a supportive role by stabilizing the shoulder joint, ensuring proper alignment and function of the arm during the movement. The deltoid, particularly its anterior fibers, assists in flexing the shoulder, allowing for a more effective range of motion when the elbow is flexed. Together, these muscles coordinate to facilitate smooth and efficient arm movement.

The prime mover of elbow flexion is the biceps brachii, which contracts to bend the elbow. The antagonist, which opposes this movement, is the triceps brachii, as it extends the elbow. During elbow flexion, the biceps brachii shortens while the triceps brachii lengthens, allowing for smooth movement.
Flexion is movement during which the knees or elbows are bent to decrease the angle of the joint
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.
Elbow flexion, shoulder flexion and supination of the forearm.
at the elbow. "Flexion of the arm" just means to bend it.
prime mover (agonist)Not sure what you're asking here, but the biceps brachii is the prime mover facilitating flexion at the elbow joint.
Triceps brachiiElbow flexion is due to the contraction of the biceps brachii, the prime mover. The triceps brachii extends as the biceps brachii contracts and therefore is the antagonist muscle.
Prime mover is the bicep and the antagonist is the tricep.
The biceps brachii muscle is primarily responsible for elbow flexion. It crosses both the shoulder and elbow joints and is a strong supinator of the forearm.
