Which joint type is joined by cartilage and allows more movement than fibrous joints, such as intervertebral discs?

• A. fibrous joints
• B. cartilaginous joints
• C. synovial joints
• D. hinge joints

Answer: (B)

Cartilaginous joints are joined by cartilage and allow more movement than fibrous joints, but not as much as synovial joints. They include primary cartilaginous joints (like growth plates) and secondary cartilaginous joints (symphyses), such as the intervertebral discs between vertebrae. The discs connect the bones with fibrocartilage, providing cushioning and enabling limited bending and twisting. In contrast, fibrous joints are tightly bound by fibrous tissue and are mostly immobile, while synovial joints are separated by a joint cavity and allow the greatest range of movement. Hinge joints are a type of synovial joint, so their mobility comes from the synovial structure rather than cartilage linking the bones.
