ANATOMY

Detailed explanation-1: -Joints which do not allow any movement of bones are called fibrous or fixed joints. These joints bind the bones closely and tightly. On the other hand, the ball and socket joint, hinge joint and pivot joint allow partial or free movement of bones. Fixed joints are present between various bones of the skull.

Detailed explanation-2: -Synarthroses (immovable joints), also known as fixed or fibrous joints, are defined as two or more bones in close proximity that have no movement. An example of immovable joints are the plates of the skull.

Detailed explanation-3: -Fixed joints are very stable and do not allow any movement. Examples are the sutures of the skull bones and the pelvic bones. Slightly moveable joints help provide stability and only allow limited movement. The individual bones are joined by cartilage.

Detailed explanation-4: -Skull joints do not move and are called immovable joints.

Detailed explanation-5: -Fixed joints do not allow any bone movement. Many of the joints in your skull are fixed (Figure below). There are eight bones that fuse together to form the cranium. The joints between these bones do not allow movement, which helps protect the brain.
