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.

2023年9月19日 · Origin, insertion, innervation and functions of the brachialis muscle. The brachialis muscle is a prime flexor of the forearm at the elbow joint. It is fusiform in shape and located in the anterior (flexor) compartment of the arm, deep to the biceps brachii.

2024年5月14日 · The brachialis is a muscle in the front of your elbow that flexes or bends the joint. It does this when your forearm is in a palm-down, pronated position. Injury to the muscle may typically cause pain and difficulty using your arm.

The brachialis is the major flexor of the elbow. It has a large cross-sectional area, providing it with more strength than the biceps brachii and the coracobrachialis. In order to isolate the brachialis muscle the forearm needs to be in pronation, due to the …

2025年2月4日 · 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.

2024年5月9日 · The brachialis muscle is a deep muscle that runs beneath the belly of the biceps brachii and is situated on the upper arm on the anterior side. The brachialis origin is slightly higher than middle way up the upper arm and the brachialis insertion is located a few centimeters past the elbow joint on the ulna.

2019年4月8日 · Training the brachialis muscle, a smaller muscle behind the biceps that acts as the primary mover of elbow flexion, can help to make your arm muscles look even bigger.

2023年2月21日 · The brachialis is an elbow flexor that originates from the distal anterior humerus and inserts onto the ulnar tuberosity. The brachialis is 1 of the largest elbow flexors and provides pure forearm flexion at the elbow. It does not provide any supination or pronation of the forearm. See Image. Internal Muscles of the Chest and Shoulder.

2024年4月29日 · The brachialis is a thick, fusiform muscle deep in the biceps brachii. Its shape and location contribute to its role as a powerful elbow flexor, particularly when the forearm is in a pronated position.
