Bone Formation

Bone formation, or ossification, is the process where new bone tissue is created. It primarily occurs during childhood growth and healing after injuries. Specialized cells called osteoblasts produce new bone matrix, which mineralizes to become hard bone. There are two main types: intramembranous ossification, where bone forms directly from connective tissue, and endochondral ossification, where cartilage is replaced by bone. Throughout life, bones constantly remodel through the activity of osteoblasts (building bone) and osteoclasts (breaking down bone), maintaining strength and adapting to mechanical needs. This dynamic process ensures healthy, functional skeletal support.
