Which connective tissue connects bone to bone?

The correct choice, which identifies the type of connective tissue that connects bone to bone, is ligament. Ligaments are fibrous connective tissues that have a high density of collagen fibers, providing stability and support to joints by holding the bones together. This connection is essential for maintaining the structure of the skeletal system and allowing for safe and efficient movement while preventing excessive motion that could lead to injuries.

In contrast, tendons connect muscle to bone, facilitating movement by transmitting the force generated by muscles to the skeletal system. Fascia is a layer of connective tissue that surrounds muscles, nerves, and blood vessels, providing support and enabling movement within these structures but does not directly connect bones. Cartilage is a flexible connective tissue found in various parts of the body, including joints, but functions primarily to cushion the ends of bones and support structures rather than connecting bone to bone.
