Function The brachialis is known as the workhorse of the elbow. It is a major flexor of the forearm at the elbow joint, flexing the elbow while it is in all positions. The brachialis is the only pure flexor of the elbow joint–producing the majority of force during elbow flexion.
The function of the brachialis is to flex your elbow, especially when your forearm is in the pronated, or palm-down, position. It has a large cross-sectional area and can produce more strength than the biceps brachii.
The brachialis (brachialis anticus) is a muscle in the upper arm that flexes the elbow. It lies beneath the biceps brachii, and makes up part of the floor of the region known as the cubital fossa (elbow pit). It originates from the anterior aspect of the distal humerus; [1] it inserts onto the tuberosity of the ulna.
Function. The brachialis is the major flexor of the elbow [3]. It has a large cross-sectional area, providing it with more strength than the biceps brachii and the coracobrachialis. [5] . In order to isolate the brachialis muscle the forearm needs to be in pronation, due to the biceps brachii's function as a supinator and flexor. [5] .
The brachialis muscle is an important muscle involved in the flexion of the forearm, located at the anterior compartment of the upper arm. It is located beneath the biceps brachii. The brachialis originates at the mid-shaft of the humerus and inserts at the coronoid process of the ulna.
Also called the brachialis anticus, its primary action is to flex the forearm muscles at the elbow. Due to its high contractile strength, the branchialis makes many arm and elbow...
Structure and Function. The brachialis is an elbow flexor that originates from the distal anterior humerus and inserts onto the ulnar tuberosity. The brachialis is one of the largest elbow flexors and provides pure flexion of the forearm at the elbow. It does not provide any supination or pronation of the forearm. See Image.
The brachialis is a long, strong muscle of the upper arm. For the most part, the brachialis is buried under the biceps brachii and is therefore not easy to palpate from the surface. The muscle does have superficial parts found at its lateral border and distally.
Functions. It works with the brachioradialis and biceps brachii muscles to flex and move the upper arm and fold the arm at the elbow. Being the primary flexor of the elbow, the muscle allows it to bend at all physiologic angles.
This one houses muscles responsible for elbow extension. So it’s also called the extensor compartment. These two compartments mainly act on the elbow joint, but some muscles can also act on the glenohumeral joint.
