BICEPS-Coracobrachialis and Brachialis

J          ANATOMY OF BICEPS PART-2

The biceps are one of the most prominent muscles in the upper arm. They are almost invariably the first muscle that gym goers exercise. A peaked bicep is the first pinnacle of achievement we aim to reach in our fitness journey.

Cracobrachialis:

Lying "deep", or under the biceps brachii, is the Coracobrachialis. the Coracobrachialis originates at coracoid process of the scapula and inserts into the medial portion of the humerus, near the deltoids tubercle. The placement of the muscle is very important in its function. The muscle passes over the shoulder joint and into the humerus, allowing this muscle to pull the humerus upwards and towards the body. In many functions it works with the deltoid and pectralis. This muscle allows you to perform exercises where you swing a weight upwar forcefully.

Brachialis:

the Brachialis is the fourth muscle and most distal muscle we will review. The brachialis originates in the lateral and  medial surfaces of the humerus. This muscle lies deep beneath the bicep brachii. insertion of this muscle is imperative to its function. coming from the humerus and over the elbow and into the ulnal tuberosity. This position assists the bicep brachii in bringing the forearms towards the humerus like in the hammer curl.

Like the coracobrachialis, the brachialis is a powerful muscle. their shortness, and position create direct power upon the joints they they cross over. Without these short muscles the bicep would be considerably weaker while note providing diverse functionality on your forearms and shoulder.
