9.2: Muscles of the Upper Arm
-
This page discusses the three main muscles of the upper arm: biceps brachii, brachialis, and triceps brachii. The biceps brachii, located at the front, flexes the forearm and originates from the scapula, inserting on the radius. The brachialis, situated beneath the biceps, arises from the humerus. The triceps brachii, found at the back, extends the forearm and works as an antagonist to the biceps with three origins. Together, these muscles are essential for arm movement and coordination.
