Brachialis
Brachialis
Brachialis (pronounced: bruh-KY-uh-lis) is a muscle in the upper arm that flexes the elbow joint. It lies deeper than the biceps brachii, and makes up part of the floor of the region known as the cubital fossa.
Etymology
The term "brachialis" is derived from the Greek word "brachion" which means arm. The term was first used in the 15th century.
Anatomy
The brachialis originates from the anterior surface of the humerus, and it inserts into the coronoid process and the tuberosity of the ulna. It is innervated by both the musculocutaneous nerve and the radial nerve.
Function
The primary function of the brachialis muscle is to flex the elbow joint. Unlike the biceps, the brachialis does not have any actions on the shoulder joint or forearm. This makes it a pure flexor of the elbow.
