Tendons are fibrous connective tissues that connect muscle to bone. They transmit the force generated by muscle contraction to facilitate movement. Tendons are composed predominantly of strong collagen fibers and are located throughout the body. Their main functions are to transmit force from muscles to bones, which allows movement, and to provide stability and shock absorption at joints. Tendons have properties like strength, elasticity, and innervation that allow them to effectively perform these functions. They are constantly adapting to demands on the body from physical activity.
