What structure connects muscles to bones?

The correct answer is tendons, which are specialized connective tissues that serve the vital function of connecting muscles to bones. When a muscle contracts, it pulls on the tendon, which in turn pulls on the bone to create movement at a joint. Tendons are designed to withstand the tension generated by muscle contractions and are composed primarily of collagen fibers, which provide strength and flexibility.

To better understand the role of tendons, it’s important to recognize their distinction from ligaments, which connect bone to bone and help stabilize joints. Cartilage, on the other hand, is a flexible tissue that cushions joints and helps facilitate smooth movement, but it does not connect muscles to bones. Fascia, although it supports and surrounds muscles and organs, does not have the specific function of connecting muscle to bone in the way that tendons do. This highlights the unique role that tendons play in the musculoskeletal system, facilitating movement and stability.
