epiphysial cartilage n.
The disk of cartilage between the shaft and the epiphysis of a long bone during its growth. Also called epiphysial plate.
The condition extends right up to the articular cartilage, or, in the case of adolescent bones, up to the epiphysial cartilage.
On section of the bones, the epiphysial cartilage and the zone of ossification are found to be unduly broad and irregular.
The activity of the epiphysial cartilage may be modified as a result of disease.
The function of the epiphysial cartilage is to provide for the growth of the shaft in length.
A tumour of bone may grow from the cellular elements of the periosteum, the marrow, or the epiphysial cartilage.
