Biceps

Biceps

Bicep, also biceps brachii (Latin for “two-headed muscle of the arm”).  Large muscle that lies on the front of the upper arm between the shoulder and the elbow. Both heads of the muscle arise on the scapula and join to form a single muscle belly. Attached to the upper forearm. While the biceps crosses both the shoulder and elbow joints, its main function is at the elbow. Where it flexes the forearm and supinates the forearm. Both these movements are used when opening a bottle with a corkscrew. First bicep unscrews the cork (supination), then it pulls the cork out (flexion).
