Joints are located where two bones connect. They allow movement and provide mechanical support.
Synovial joints have a fibrous articular capsule lined with synovial membrane surrounding a joint cavity.
Although there are many joints in the skull, most are fused or immovable. The only bone that is free moving is the mandible, the lower jaw. The joints that connect the tooth to the socket are gomphosis joints, which allow little to no movement.
A synovial joint moves the most freely.
If you count the true arm: The shoulder has a ball and socket joint. The elbow has a hinge joint (ulna) and a pivot joint (radius). If you count the forearm: The forearm has a fibrous joint (syndesmosis) between the radius and ulna. The wrist is a very complex set of joints, if I remember correctly they are mostly saddle joints and gliding joints.
The joints that are most remembered for their sutures are the fibrous joints. These joints only occur in the skull and are bound together by Sharpey's fibers.

The thumbs have saddle type joints, which allow the thumb to oppose the palm, but the most freely movable joints are the ball and socket joints of the hips and shoulders.
A synovial joint moves the most freely.
The joints in the body that have the most movement are called synovial joints, or freely moving joints. Technically they are classified as diarthrotic joints. The difference between synovial joints and the other types of joints is that they contain a synovial sheath that supplies them with synovium, a lubricating fluid. Of the six different types of synovial joints the ball-and-socket joints have the greatest amount of movement. The four ball-and-socket joints in the human body are the ileofemoral joints, hip joints, and the glenohumeral joints, the shoulders.

Joints come in three different varieties. The least movable are the synarthrotic. The example of these are the suture joints in the cranium. They are not fused together, but rather, separated by a very thin cartilage. The next, more movable joints are the amphiarthrotic joints. These are found between the vertebrae of the spine. The most movable are the diarthrotic joints, also called freely moving, or synovial joints. There are six types; ball-and-socket, hinge, pivot, gliding, saddle, and ellipsoidal.
Cartlige & tendons and don't forget the synovial fluid that keeps everything freely moving
