The Biceps flex the elbow
The Triceps extend the elbow
triceps brachii
The triceps brachii muscle does not flex the elbow; it is responsible for extending the elbow joint when it contracts.
The function of the biceps brachii is to flex your arm at the elbow. However, even though that is the most visible muscle, the brachialis muscle is considered the prime mover in flexing at the elbow.
It either expands or contracts depending on which way you're bending your elbow.
A chicken's wing has muscles that control the movement of the elbow joint. These muscles contract and relax to move the wing up and down, allowing for flight and other wing-related activities. The tendons in the wing help transmit the force generated by the muscles to the bones, enabling movement at the elbow joint.
None. Muscles only contracts. In order to extend, the muscle on the opposite movement has to contract. For example, the biceps help flex the elbow, but it does not extend the elbow; the triceps does that.
extensorThe triceps brachii is an extensor. It is the large muscle on the back of the arm and is primarily the muscle used for extension of the elbow joint or straightening of the arm. The triceps is also an antagonist of the biceps and the brachialis muscles.ExtensorsTriceps is not a flexor. It is extensor of the elbow joint.
The brachioradialis is a muscle found in the forearm that helps flex the forearm at the elbow. It is capable of pronation and supination.
The primary antagonist of the brachialis muscle is the triceps brachii muscle. When the brachialis contracts to flex the elbow, the triceps relaxes to allow this movement.
The elbow joints flex to decrease the angle between the forearm and upper arm, allowing for movements like bending the arm or bringing the hand closer to the shoulder. This action is controlled by the biceps muscle, which contracts during flexion.
flex the elbow
The bicep is a muscle on the upper arm that is designed to rotate the forearm and flex the elbow. See link below for more information.
