Cartilage grows in two ways, appositional and interstitial. What is appositional growth?

• The secretion of new matrix against the external face of existing cartilage

• along the edges only of existing osteons, making each osteon larger

• the lengthening of hyaline cartilage

• growth at the epiphyseal plate

Which of the following statements best describes interstitial growth?

• Fibroblasts give rise to chondrocytes that differentiate and form cartilage

• Unspecialized cells from mesenchyme develop into chondrocytes, which divide and form cartilage

• Growth occurs in the lining of the long bones

• Chondrocytes in the lacunae divide and secrete matrix, allowing the cartilage to grow from within
