Which is a structural classification describing joints connected by fibrous tissue with no joint cavity?

• A. Fibrous
• B. Cartilaginous
• C. Synovial
• D. Bony

Answer: (A)

Joints are classified by the tissue that binds the bones and whether a joint cavity is present. When bones are joined by dense fibrous connective tissue and there is no joint cavity, that describes fibrous joints. This group includes sutures between skull bones, syndesmoses like the connection between the tibia and fibula, and gomphoses attaching teeth to the jaw. Cartilaginous joints are bound by cartilage rather than fibrous tissue, even though they also lack a joint cavity. Synovial joints, in contrast, have a fluid-filled joint cavity and an articular capsule. Bony joints describe fused bones with no cavity, but they’re not defined by being connected specifically by fibrous tissue. So the description matches fibrous joints.
