Brachialis is a muscle located in the upper arm, primarily responsible for flexing the elbow joint. It lies beneath the biceps brachii and is a key player in bending the forearm independently of forearm rotation. This muscle provides significant strength to movements involving lifting and pulling.
The name "brachialis" is derived from the Latin word "brachium," meaning "arm," highlighting its anatomical position and function within the upper arm.
Without the brachialis, the human body would experience reduced efficiency in flexing the elbow, hampering activities involving pulling, lifting, or carrying objects due to a significant loss in elbow joint flexion power.
