- Epiphyseal plate is a layer of hyaline cartilage.
- Consists of cells (chondrocytes) of a rounded or bluntly angular, form, lying in groups of two or more in a granular or almost homogeneous matrix.
- ytes are cartilage cells that produce the matrix.
- When arranged in groups of two or more, chondrocytes have generally straight outlines where they are in contact with each other, and in the rest of their circumference are rounded.
- They consist of clear translucent protoplasm in which fine interlacing filaments and minute granules are sometimes present; embedded in this are one or two round nuclei, having the usual intranuclear network.
