Which process involves the formation of new bone tissue?

• A. osteolysis
• B. ossification
• C. remodeling
• D. calcification

Answer: (B)

Ossification is the process of forming new bone tissue. It starts with osteoblasts laying down osteoid, which then mineralizes to become hard bone. There are two main pathways: intramembranous ossification, which forms flat bones, and endochondral ossification, which replaces a cartilage model to form most long bones. Osteolysis is bone resorption, the breakdown of bone. Remodeling is the lifelong cycle where old bone is replaced by new bone, involving both resorption and formation. Calcification is the deposition of calcium salts, which occurs during mineralization but does not by itself describe the formation of new bone tissue.
