WebChondrocytes in the physis can be divided into a series of layers or zones (Figure 54-3). The zone farthest from the metaphysis is the resting or reserve zone. Adjacent to this is the proliferative zone, in which chondrocytes divide. These cells progress to the hypertrophic zone, in which they enlarge and form ordered columns.
