The three main types of joints are fibrous joints, cartilaginous joints, and synovial joints. Fibrous joints are immovable and connect bones with fibrous tissue, like skull sutures. Cartilaginous joints allow limited movement and connect bones with cartilage, such as intervertebral discs. Synovial joints permit more movement than the other types and connect bones ends covered in cartilage within a capsule filled with synovial fluid. Examples of synovial joints include ball-and-socket, hinge, condylar, ellipsoid, saddle, and plane joints.
