Why is interstitial growth possible in cartilage but generally NOT in mature bone?
Show answer and explanation
Correct answer: Cartilage matrix is flexible and expandable, but bone is rigidly calcified.
The hydrated, proteoglycan-rich matrix of cartilage is flexible enough to allow internal expansion as cells divide. In contrast, the mineralized hydroxyapatite of bone prevents cells from moving apart after division.
