In general, these disks have two functions: to allow movement between pairs of vertebrae and to act as buffers against shock caused by running, jumping, and other stresses applied to the spine. A similar situation takes place in the seventh sternochondral joint. The epiphyseal plate of growing long bones and the first sternocostal joint that unites the first rib to the sternum are examples of synchondroses. The sternal ends of the costal cartilages have a large and convex, almost semiround shape in the coronal plane. Cartilaginous joints allow little movement, as summarized above. Examples are the synchondroses between the occipital and sphenoid bones and between the sphenoid and ethmoid bones of the floor of the skull. This uniplanar motion involves a gliding, or sliding motion in a linear direction between the articular surfaces of the sternal costal notches and the corresponding sternal ends of the costal cartilages. You can help Wikipedia by expanding it. Fibrocartilage is very strong because it contains numerous bundles of thick collagen fibers, thus giving it a much greater ability to resist pulling and bending forces when compared with hyaline cartilage. A synovial joint consists of a wall enclosing a joint cavity that is wholly filled with synovial fluid. All intervertebral disks allow approximation and separation of their adjacent vertebrae. This cartilage may Many athletes experience symphysis when they are playing in their sports fields. Edinburgh: Churchill Livingstone, Gray, D. J., & Gardner, E. D. (1943). The joint is flexible enough to act as a hinge that allows each of the two hip bones to swing a little upward and outward, as the ribs do during inspiration of air. A synchondrosis is a cartilaginous joint where the bones are joined by hyaline cartilage. Articular surfaces are divisible into two primary classes: ovoid and sellar. Author: PMID29379710.
