johtojänteitä

Johtojänteitä, known in English as tendons, are tough bands of fibrous connective tissue that connect muscle to bone. They are essential for locomotion, enabling muscles to exert force and move skeletal structures. Tendons are composed primarily of collagen, a strong and flexible protein that allows them to withstand significant tensile stress. Their structure is highly organized, with collagen fibers arranged in parallel bundles, which further enhances their strength and efficiency in transmitting force.

The elasticity of tendons plays a crucial role in movement. They can store and release energy during activities like running or jumping, acting like springs that help to propel the body. This elastic recoil contributes to the efficiency of movement and can reduce the energetic cost of locomotion. Tendons are also important for maintaining posture and stabilizing joints.

Injuries to tendons, such as strains and tears, can occur due to overuse, sudden forceful movements, or trauma. These injuries can be painful and may require significant recovery time, impacting an individual's mobility. Conditions like tendinitis, an inflammation of the tendon, and tendinosis, a degenerative condition, are common tendon ailments. Prevention strategies often involve proper warm-up exercises, gradual increases in activity intensity, and appropriate training techniques.
