Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Bone formation is ____
A
ossification
B
bone resorption
C
fracture repair
D
None of the above
Explanation: 

Detailed explanation-1: -Bone ossification, or osteogenesis, is the process of bone formation. This process begins between the sixth and seventh weeks of embryonic development and continues until about age twenty-five; although this varies slightly based on the individual.

Detailed explanation-2: -Ossification (also called osteogenesis or bone mineralization) in bone remodeling is the process of laying down new bone material by cells named osteoblasts. It is synonymous with bone tissue formation.

Detailed explanation-3: -Ossification is the process of bone formation by osteoblasts. Intramembranous ossification is the process of bone development from fibrous membranes. Endochondral ossification is the process of bone development from hyaline cartilage. Long bones lengthen as chondrocytes divide and secrete hyaline cartilage.

Detailed explanation-4: -What are examples of intramembranous ossification? Flat bones from the skull, the pelvis, and the clavicles develop from the intramembranous ossification process, which differentiates the mesenchymal tissue into compact bone.
