APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Immovable – the two or more bones are in close contact, but no movement can occur – for example, the bones of the skull. The joints of the skull are called sutures.

Detailed explanation-2: -A joint which permits no kind of movement is called as an immovable joint or fixed joint. In such joints, bones have been fused together in such a way that they are fixed to that part. Such joints are found in the skull, upper jaw, rib cage, backbone, pelvic bone, etc.

Detailed explanation-3: -Fibrous joints are connected by dense connective tissue consisting mainly of collagen. These joints are also called fixed or immovable joints because they do not move. Fibrous joints have no joint cavity and are connected via fibrous connective tissue.

Detailed explanation-4: -Immovable joints allow no movement because the bones at these joints are held securely together by dense collagen. The bones of the skull are connected by 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.
