Which structure do tendons primarily connect?

Tendons primarily connect muscles to bones, facilitating movement by transmitting the force generated by muscle contractions to the skeletal system. This connection is critical for the functioning of the musculoskeletal system, as it allows for the coordinated movement of limbs and other body parts. Tendons are composed of densely packed collagen fibers, which provide the strength and flexibility needed to withstand the stresses of physical activity. This function distinguishes tendons from other anatomical structures, such as ligaments, which connect bones to bones, and muscles, which primarily interact with other muscles at specific joints. Understanding the role of tendons in connecting muscles to bones is fundamental in tissue engineering, especially when developing strategies for repairing or regenerating musculoskeletal tissues.
