The Biceps Brachii is a prominent muscle located in the upper arm. It consists of two heads, the long head and the short head, which originate from different points on the shoulder blade and converge to form a single muscle belly. This muscle is primarily responsible for flexing the elbow and rotating the forearm. In addition to its role in arm movement, the Biceps Brachii plays a part in stabilizing the shoulder joint. It is commonly targeted in strength training exercises, such as curls, to enhance arm strength and appearance. Proper conditioning of this muscle is important for overall upper body function.
