Question

In growing cartilage, the chondroblasts associated with the perichondrium are responsible for
A) interstitial growth.
B) appositional growth.
C) endochondral growth.
D) calcification.

Accepted Answer

Chondroblasts associated with the perichondrium are responsible for appositional growth, which is the addition of new cartilage tissue to the surface of existing cartilage. Interstitial growth occurs from within the cartilage matrix by chondrocytes dividing and secreting new matrix. Endochondral growth refers to the replacement of cartilage by bone during bone formation. Calcification is the process of depositing calcium salts into cartilage tissue, which occurs during endochondral ossification.
