For intramembranous ossification to take place, which of the following is necessary?
A) Ossification centers form in the fibrous connective tissue membrane.
B) The cartilage matrix begins to deteriorate.
C) A medullary cavity forms.
D) A bone collar forms around the cartilage model.

Question

Quizplus · Accepted Answer

Intramembranous ossification occurs when ossification centers form within a fibrous connective tissue membrane. This process is different from endochondral ossification, which occurs when a cartilage model is transformed into bone. The deterioration of cartilage matrix and formation of a bone collar are steps in endochondral ossification, not intramembranous ossification. A medullary cavity, which is a hollow space within a bone, is also not necessary for intramembranous ossification.
