Valtajänteen

Valtajänteen is a Finnish term that translates to "main tendon" or "central tendon." It most commonly refers to the central tendon of the diaphragm, a large, dome-shaped muscle located at the base of the chest cavity that plays a crucial role in breathing. This tendon is a strong, fibrous structure where the muscular fibers of the diaphragm converge. During inhalation, the diaphragm contracts and flattens, pulling downward and increasing the volume of the thoracic cavity. The central tendon moves downwards with this contraction, allowing the lungs to expand and fill with air. During exhalation, the diaphragm relaxes, and the abdominal organs push it back upwards, expelling air from the lungs. The integrity and function of the Valtajänne are essential for efficient respiration. In anatomical contexts, the term emphasizes the tendon's role as a primary anchoring point and central component of this vital muscle. It is a key structure in understanding the mechanics of breathing and the overall function of the respiratory system.
