Küünarnuki
Küünarnuki is an Estonian word that translates to "elbow" in English. It refers to the joint in the middle of the arm, where the upper arm bone (humerus) connects to the two forearm bones (radius and ulna). This joint is crucial for a wide range of movements, including bending and straightening the arm. The elbow joint allows for flexion, extension, pronation, and supination of the forearm. It is a complex structure composed of bone, cartilage, ligaments, and muscles that work together to provide both stability and mobility. Common issues related to the küünarnuki include sprains, fractures, and conditions like tennis elbow or golfer's elbow, which are forms of tendinitis affecting the tendons around the joint. The health and proper functioning of the küünarnuki are essential for everyday activities such as lifting, carrying, and reaching.
