Tendons
Tendons are tough bands of fibrous connective tissue that connect muscles to bones. They are essential for the movement of the body and play a crucial role in transmitting the forces generated by muscles to the bones, resulting in movement at the joints.
Structure of Tendons
Tendons are composed of densely packed parallel collagen fibers, which provide strength and flexibility. The collagen fibers are arranged in a hierarchical structure, with bundles of collagen fibrils forming larger fibers, and these fibers combining to form the tendon. This structure allows tendons to withstand tension and transmit forces efficiently.
Functions of Tendons
1. Transmitting forces: Tendons transmit the forces produced by muscles to the bones, allowing movement at the joints.
2. Storing and releasing energy: Tendons act like springs, storing and releasing energy during movement, which is especially important in activities such as running and jumping.
3. Providing stability: Tendons help stabilize the joints and prevent excessive movement.
Common Injuries and Care
Common injuries to tendons include tendinitis (inflammation of the tendon) and tendon tears. Proper care and prevention of these injuries involve:
1. Gradual warm-up before exercise
2. Stretching and flexibility exercises
3. Adequate rest and recovery
4. Proper nutrition to support tendon health
