Document Summary
Joints are articulations where two or more bones meet. Joints hold bones together and allow for mobility. Functional classi cation: synostosis are immovable joints, synarthroses are immovable joints, amphiarthroses are slightly movable joints, diarthroses are freely movable joints. Structural classi cation: bony joints are immobile joints, brous joints are generally immovable, cartilaginous joints are immovable or slightly movable, synovial joints are freely movable. Synopses are immovable joints that form when the gap between two bones ossi es and it becomes a single bone, either brous or cartilaginous joints may ossify. Brous joints (synarthroses) are found where collagen bers emerge from the matrix of one bone, cross a space, and penetrate the metric of another bone: sutures - immobile or slightly movable joints of skull bones. Bers bind two bones (ex. ulna and radius, tibia and bula) Cartilaginous joints (amphiarthroses) are formed when two bones are linked by cartilage: synchondroses (immobile)
