Ossification is the process of laying down new bone material by cells called Osteoblasts.
Endochondral ossification

The bone ossification test conducted to ascertain human age is called dental or skeletal ossification testing. Dental ossification testing involves assessing the development of teeth, while skeletal ossification testing involves assessing the fusion of growth plates in long bones to estimate a person's age.
The horns of the giraffe are a direct result of ossification. As such, they are not properly referred to as horns, but as ossicones.The process of ossification of the human body begins around the second month of fetal life.
Intramembranous ossification is the process by which osteoblasts lay down bone within a connective tissue membrane, leading to the formation of flat bones such as the skull and ribs.

Intramembranous and Endochondral Ossification
Ossification (or osteogenesis) is the generic term for bone formation. There are two basic types: membranous ossification and endochondral ossification.
Ossification occurs when bones are formed.
Intramembranous ossification
There are two ways bones are formed, intramembranous ossification, and endochondral ossification. Intramembranous ossification is how the flat bones are formed, while the long bones are formed with endochondral ossification.
Endochondral ossification is the type of ossification in bones that are formed in cartilage. This process involves the replacement of cartilage by bone during development and growth.
Secondary ossification centers appear in the epiphyses.
