Document Summary
As strength increases, mobility decreases and vice versa. Anatomical/structural: presence of space between bones; type of connective tissue holding the bones together. Bones held tightly together by fibrocartilage or hyaline cartilage. Synarthrosis: immovable; very strong; edges of bone may touch or interlock. Binds teeth to bony sockets in the maxillae and mandible. Examples: epiphyseal plate, joint between ribs and sternum. Amphiarthrosis: slightly movable; more movable than synarthrosis; stronger than a freely moving joint. Diathrosis: freely movable; synovial cavity separates articulating bones; lines with synovial membrane; filled with synovial fluid; typically located at the ends of long bones; found within articular capsules. All synovial joints are surrounded by a joint capsule. The synovial membrane lines the inside of the joint capsule and produces synovial fluid. Articular cartilages pad the bony surfaces of articular bones. Interstital fluid-like solution containing proteoglycans and high conc. of hyaluronic acid.
