küünarnukk

Küünarnukk is the Estonian word for elbow. The elbow is the joint between the upper arm and the forearm. It is a hinge joint, primarily allowing for flexion and extension of the forearm. It is also capable of a limited degree of rotation, contributing to pronation and supination of the hand. The elbow joint is formed by the articulation of three bones: the humerus in the upper arm, and the radius and ulna in the forearm. Several ligaments, including the collateral ligaments, provide stability to the joint. Muscles such as the biceps and triceps are crucial for its movement. The elbow joint is susceptible to various injuries, including sprains, fractures, and dislocations, as well as conditions like tennis elbow and golfer's elbow, which are forms of tendinitis.
