The epiphyseal plate (or epiphysial plate, physis, or growth plate) is a hyaline cartilage plate in the metaphysis at each end of a long bone.It is the part of a long bone where new bone growth takes place; that is, the whole bone is alive, with maintenance remodeling throughout its existing bone tissue, but the growth plate is the place where the long bone grows longer (adds length). Either rounded end of a long bone is called an epiphysis, and the shaft of the bone is called the diaphysis. The functional classification of joints is determined by the amount of mobility found between the adjacent bones Joints are thus functionally classified as a synarthrosis or immobile joint an amphiarthrosis or slightly moveable joint or as a diarthrosis which is a freely moveable joint arthroun “to fasten by a joint” It forms a visible line called the epiphyseal line.
