küünarnukki

KÜÜNARNUkkI is the Estonian word for elbow. The elbow is the joint in the middle of the arm, where the upper arm bone (humerus) connects to the two forearm bones (radius and ulna). It is a hinge joint, allowing for the flexion and extension of the arm.

The elbow joint is crucial for a wide range of movements, from simple tasks like eating and writing to more complex actions such as throwing and lifting. The joint is surrounded by a capsule and supported by several ligaments, which provide stability. Muscles and tendons also play a vital role in enabling movement at the elbow.

Injuries to the elbow can range from sprains and strains to fractures and dislocations. Repetitive stress can lead to conditions like tennis elbow or golfer's elbow. The elbow's prominent position also makes it susceptible to contusions and abrasions. Anatomically, the elbow consists of three articulations: the humeroulnar joint, the humeroradial joint, and the proximal radioulnar joint. These articulations work together to provide the full range of motion experienced at the elbow.
