primary center of ossification
Zone of reserve (resting) cartilage—this zone appears as an area of typical hyaline cartilage. Zone of proliferative chondrocytes—characterized by chondrocytes that are arranged in rows (like stacks of coins). Zone of mature (hypertrophied) chondrocytes—in this zone, both the chondrocytes and lacunae have enlarged at the expense of the matrix, reducing it (the matrix) to thin strands. Zone of calcified chondrocytes/cartilage matrix—
