Document Summary
Self-review anatomy and physiology (know landmarks and bony prominences) Purpose is for support, movement, protection, reservoir for essential minerals. In nonsynovial joints, the bones are united by fibrous tissue or cartilage and are immovable (e. g. , the sutures in the skull) or only slightly movable (e. g. , the vertebrae) Synovial joints are freely movable because they have bones that are separated from each other and are enclosed in a joint cavity. This cavity is filled with a lubricant: synovial fluid. Synovial fluid allows sliding of opposing surfaces, and this sliding enables movement. In synovial joints, a layer of resilient cartilage covers the surface of opposing bones. Cartilage is avascular; it receives nourishment from synovial fluid that circulates during joint movement. It is a very stable connective tissue with a slow cell turnover. It has a tough, firm consistency and yet is flexible. Cartilage cushions the bones and provides a smooth surface to facilitate movement.
