brachialis,brachioradialis, triceps brachil
The brachioradialis is a muscle found in the forearm that helps flex the forearm at the elbow. It is capable of pronation and supination.
Function: flexion and radial deviation of the wrist, along with other muscles which flex the wrist and radially deviate the wrist, weak pronation of the forearm along with other muscles which pronate the forearm and weak flexion of the elbow along with other muscles which flex the elbow
brechioradialis
The bicep flexes the arm at the elbow.
Flexion (same as bending) at the elbow joint (between the humerus and the radius and ulna) is mainly achieved by the Brachialis Muscle. This is not the answer most would expect as everyone knows the Biceps Brachii (Biceps of the arm) are what flexes this joint. In fact the biceps does both supination and flexion of the elbow because its insertion is on the radius. Only when the forearm is supinated, the biceps is able to assist the deeper and more powerful brachialis muscle with the flexion of the elbow.
The triceps muscles extend (straighten) the arm, while the biceps muscles flex (bend) it at the elbow joint.
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.
The Biceps flex the elbow The Triceps extend the elbow
The triceps brachii muscle does not flex the elbow; it is responsible for extending the elbow joint when it contracts.
No. The Biceps Brachii and another muscle called the brachialis bend the elbow. The Biceps Brachii also helps rotate the wrist in the direction called supination and helps to forward flex the shoulder.
flex the elbow
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.
