The processes of intramembranous and endochondral ossification are similar in several respects. Which of the following statements applies to both intramembranous and endochondral ossification? A. Both processes require a precursor of connective tissue membranes.

B. Both processes form woven bone.

C. Both only form flat bones.

D. Chondrocytes participate in both processes.

E. In both processes, bone replaces cartilage.

B. Both processes form woven bone.

Explanation:

Bone growth and development is mainly characterized by bone ossification processes taking place through the two main osteogenic pathways - intramembranous and endochondral ossification.

The woven bones are the primary immature bones formed by both these ossification processes from the bone cells (osteoclasts, osteocytes, osteoblast) and calcified bone matrix. These woven cells later developed into the mature secondary bones or the lamellar bones - spongy (cancellous) or compact (dense cortical) bones.

Intramembranous ossification takes place mesenchymal sheets of connective tissues and produces soft spongy bones.

Endochondral ossification results in replacement of hyaline cartilage to form the long bones.
