What structure connects one bone to another bone?

The structure that connects one bone to another is a ligament. Ligaments are fibrous connective tissues that play a crucial role in stabilizing joints and ensuring proper movement between bones. They are designed to withstand the tensile forces that occur during motion, providing both support and flexibility to the skeletal system.

In contrast, tendons connect muscles to bones, facilitating movement by transferring the force generated by muscle contraction to the bone. Cartilage serves as a cushion between bones at joints, reducing friction and acting as a shock absorber, but it does not directly connect bones to one another. Muscles are responsible for movement but do not serve as connective structures between bones.

Understanding the specific roles of these structures highlights why ligaments are essential for maintaining the integrity of joints and supporting the skeletal framework during various activities.
