MICROANATOMY

Detailed explanation-1: -Fixed joints protect the delicate organs like brain in our body.

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: -The ribs form a cage that shelters the heart and lungs, and the pelvis helps protect the bladder, part of the intestines, and in women, the reproductive organs.

Detailed explanation-4: -Synovial joints allow for movement. Where the bones meet to form a synovial joint, the bones’ surfaces are covered with a thin layer of strong, smooth articular cartilage. A very thin layer of slippery, viscous joint fluid, called synovial fluid, separates and lubricates the two cartilage-covered bone surfaces.

Detailed explanation-5: -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.
