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.
prime mover (agonist)Not sure what you're asking here, but the biceps brachii is the prime mover facilitating flexion at the elbow joint.
at the elbow. "Flexion of the arm" just means to bend it.
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.
