I got a question from a textbook <<Seeley's Anatomy & Physiology Twelfth Edition>> that does not have an answer at the back of the book (only odd numbered questions do have an answer and this question is even):
Explain why bones cannot undergo interstitial growth as cartilage does.
i can only think of two reasons:
In bones, calcification causes the chondrocytes to die, so cartilage cannot form in the bone, leading to no interstitial growth in the bone.
Cartilages are usually only found at the tip of the bones, so its growth can cause the bone to lengthen, which is interstitial growth.
I got a nagging feeling that there is got to be more. Did i miss any other reason? (Also are my reasons correct?)
