küünarnukist

Küünarnukk is the Estonian word for elbow. The elbow is the joint connecting the upper arm to the forearm. It is a complex hinge joint that allows for flexion and extension of the forearm. The elbow also permits some degree of pronation and supination, which are movements of the forearm that turn the palm up or down. Three bones form the elbow joint: the humerus (upper arm bone), the ulna (one of the forearm bones), and the radius (the other forearm bone). Ligaments and muscles also play a crucial role in stabilizing and enabling the movement of the elbow. Common issues affecting the elbow include sprains, dislocations, and conditions like tennis elbow or golfer's elbow, which are types of tendinitis. The elbow is essential for a wide range of everyday activities, from lifting and carrying to writing and manipulating objects.
