What connects one bone to another in the human body?

The connection between one bone and another in the human body is facilitated by ligaments. Ligaments are tough, flexible bands of connective tissue that surround joints, providing stability and support while allowing for a controlled range of motion. They play a crucial role in maintaining the structural integrity of the skeletal system by binding bones together and reinforcing the joints.

Tendons, on the other hand, connect muscles to bones and are not involved in connecting bones to each other. Cartilage serves as a cushioning material that reduces friction between bones in joints but does not connect them directly. Muscle fibers are involved in the movement of bones through contraction but also do not connect bones to one another. Thus, ligaments are specifically designed for the function of connecting bones, making this the correct answer.
