Document Summary
Fibrous joints: bones joined together by fibrous ct, which is usually called a ligament . Tissue: dense regular ct: suture: very short fibers, only in skull. Example: maxillary bones: cleft palate: l and r fail to form a suture: sydesmosis: length of fibers vary and determine mobility. Example: interosseous membrane between radius and ulna, fibers are long. Mobility: diarthrotic: gomphosis: peg in socket. Cartilaginous joints: bones joined by cartilage: synchondrosis: bones united by hyaline cartilage. Example: 1st sternocostal joint (joint between 1st rib and sternum) Mobility: synarthrotic: symphysis: main cartilage if fibrocartilage (tension resistant), hyaline. Synovial joints: bones separated by a fluid-containing joint cavity, and are freely movable, Nourishes articular cartilage indirectly from blood via fluid. Examples: knee, shoulder, knuckle, wrist, most ribs and sternum. Articular cartilage: hyaline cartilage, absorbs compression forces and protects bones. Allows additional movements: example: temporomandibular (jaw) joint. Sternoclavicular joint (not typical: multi-axial: ball-and-socket joint, most free moving joint/movement around all axes, multiaxial, only examples: c. i.
