Which connective tissue is responsible for attaching bone to bone?

Ligaments are specialized connective tissues that serve the essential function of connecting bones to other bones at joints. They are composed of dense connective tissue, which provides strength and stability to the skeletal system, ensuring that bones remain in the correct positions during movement and weight-bearing activities. This unique role of ligaments is critical in maintaining the integrity of the joints, helping to prevent injuries such as sprains that can occur when ligaments are overstressed.

While tendons connect muscles to bones, and muscle tissue itself plays a role in movement and stabilizing joints, these do not perform the specific function of connecting bones to each other. Therefore, ligaments are the correct answer as they uniquely fulfill the role of attaching bone to bone.
