Hauisjänteen

Hauisjänteen, often referred to as the "biceps tendon," is a crucial anatomical structure in the human arm. It is the strong, fibrous connective tissue that attaches the biceps brachii muscle to the bones of the shoulder and elbow. There are two main tendons associated with the biceps brachii: the long head and the short head. The long head of the biceps tendon originates from the supraglenoid tubercle of the scapula, passes through the shoulder joint, and then descends down the arm. The short head of the biceps tendon originates from the coracoid process of the scapula and also runs down the arm.

Both tendons converge and insert onto the radial tuberosity of the radius bone in the forearm. The primary function of the biceps brachii muscle, facilitated by its tendons, is to flex the elbow (bending the arm) and to supinate the forearm (rotating the palm upwards). The long head of the biceps tendon also plays a significant role in stabilizing the shoulder joint, particularly during overhead movements. Injuries to the hauisjänteen can range from tendinitis, an inflammation of the tendon, to a complete rupture, where the tendon tears away from its attachment. These injuries often result in pain, weakness, and a visible deformity in the arm.
