Arm Power: A thorough model to the Three Heads of the Triceps
The triceps brachii muscle is located on the back of the upper arm and is composed of three distinct heads: the long head, the lateral head, and the medial head. The long head originates from the infraglenoid tubercle of the scapula, playing a vital role in shoulder extension. The lateral head, found on the outer humerus, contributes significantly to arm aesthetics. The medial head, originating below the radial groove, is crucial for arm extension, ensuring coordination for movements like pushing.
