Here's a breakdown of the process:
* Intramembranous Ossification: This occurs directly within a membrane of connective tissue. It is how flat bones, like the skull, are formed.
* Endochondral Ossification: This involves the replacement of hyaline cartilage by bone. This is how most bones in the body are formed.
Key Points:
* Ossification is essential for the development and maintenance of the skeletal system.
* It is a complex process involving various cells, growth factors, and signaling pathways.
* It begins during fetal development and continues throughout life.
* It is responsible for the growth and repair of bones.
Note: The term "ossification" is often used interchangeably with "bone formation," but it technically refers to the specific process of cartilage replacement by bone tissue.
