In Plain English
The biceps are the prominent muscles at the front of the upper arm, running from the shoulder to the forearm. They bend the elbow, rotate the palm upward, and help pull the upper arm forward, making them essential for pulling movements and one of the most recognizable muscles in the body.
Technical Definition
The biceps brachii is a two-headed muscle consisting of a long head and short head, originating from the supraglenoid tubercle and coracoid process of the scapula before inserting onto the radial tuberosity. Its primary functions are elbow flexion, forearm supination, and shoulder flexion, with its attachment to the radius making it the strongest supinator of the forearm when the elbow is flexed.
