kyynärpäille

Kyynärpäille refers to the plural form of kyynärpää in Finnish, which translates to "elbow" in English. The elbow is the joint connecting the upper arm to the forearm. It is a crucial hinge joint that allows for flexion and extension of the arm, as well as supination and pronation of the forearm. The elbow joint is formed by three bones: the humerus in the upper arm, and the radius and ulna in the forearm. These bones are held together by a complex network of ligaments, and the joint is surrounded by a capsule filled with synovial fluid, which lubricates the joint and allows for smooth movement.

The muscles responsible for elbow movement are located in the upper arm and forearm. The biceps brachii and brachialis muscles, located in the front of the upper arm, are primarily responsible for flexing the elbow, bringing the forearm towards the upper arm. The triceps brachii muscle, located on the back of the upper arm, extends the elbow, straightening the arm. The muscles of the forearm, along with the radius and ulna, are involved in the rotational movements of pronation (turning the palm downwards) and supination (turning the palm upwards).

The elbow is susceptible to various injuries and conditions, including sprains, fractures, dislocations, tendinitis, and arthritis. Repetitive motions, such as those involved in certain sports or occupations, can lead to overuse injuries like tennis elbow or golfer's elbow, which involve inflammation of the tendons attaching to the epicondyles of the humerus. Proper care and attention to the health of the elbow joint are important for maintaining mobility and function.
