Name and briefly describe the two types of growth seen in cartilage
What will be an ideal response?
Growth of cartilage can be classified as interstitial or appositional. In interstitial growth, the cartilage increases rapidly in size due to the division of existing chondrocytes and the continuous deposition of increasing amounts of matrix by the chondrocytes. In appositional growth, activity of the cells in the inner chondrogenic layer of the perichondrium leads to growth. Deeper layers divide and cells mature resulting in the matrix accumulating beneath the perichondrium on the outer surface of the cartilage causing it to grow in width.
