Cartilaginous joints allow only slight movement and consist of bones connected entirely by cartilage.

• A. Fibrous joints
• B. Synovial joints
• C. Cartilaginous joints
• D. Hinge joints

Answer: (C)

Joints are categorized by what binds the bones and how much they move. When bones are connected entirely by cartilage, the joints are cartilaginous and allow only slight movement (amphiarthrosis). Examples include the pubic symphysis and the intervertebral joint areas. This is different from fibrous joints, which are bound by dense connective tissue and are mostly immovable, and from synovial joints, which have a joint cavity and permit a wide range of motion. Hinge joints are a specific type of synovial joint that moves mainly in one plane. So the description fits cartilaginous joints.
