Description
This lesson covers bone formation, also known as Ossification. It occurs through different mechanisms during development, growth, remodeling, and fracture repair. Intramembranous ossification directly converts mesenchymal tissue into bone. It is responsible for forming flat bones, such as most of the bones of the skull.
