Ossification means bone growth or formation. I will be disscussing breifly normal or physiological ossification because there is pathological ossification.There are two types of ossification in the human body: endochondral and intramembranous.
Most of the bones in the human skeleton , especially the long and short bones, develop via endochondrial ossification, but some including the clavicle and most of the bones of the skull( flat bones) are formed by the intramembranous type.
Intramembranous ossification , the source of most of the flat bones, is so called because it takes place within condensations of mesenchymal tissue and not by replacement of pre-existing piece of hyaline cartilage as the case in endochondral ossification. The frontal and parietal bones of the skull, as well as parts of the temporal and occipital bones and the mandible and maxilla, are formed by intra membranous ossification. This process also contributes to the growth of short bones and the thickening (not the lengthening) of long bones.

Ossification of flat bones is called?
Intramembranous ossification
What does Intramembranous ossification produce?
it produces the flat bones of the skull and most of the clavicle (collarbone)
Cranial bones and other flat bones develop?
The calvaria including the parietal, frontal, temporal,and occipital bones form by intramembranous ossification. The skull base develops via endochondral ossification.
Bones of the skull and clavicle develop by?
The clavicles and the cranial bones of the skull develop from a fibrous membrane. This process is known as intramembranous ossification.
Of what four things are bones made?
Almost every bone in your body is made of the same materials:The outer surface of bone is called the periosteum (say: pare-ee-os-tee-um). It's a thin, dense membrane that contains nerves and blood vessels that nourish the bone.The next layer is made up of compact bone. This part is smooth and very hard. It's the part you see when you look at a skeleton.Within the compact bone are many layers of cancellous(say: kan-sell-us) bone, which looks a bit like a sponge. Cancellous bone is not quite as hard as compact bone, but it is still very strong.In many bones, the cancellous bone protects the innermost part of the bone, the bone marrow (say: mair-oh). Bone marrow is sort of like a thick jelly, and its job is to make blood
Most bones of the body form by which type of ossification?
Intramembranous ossification
How was bones form?
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.
Ossification of flat bones is called?
Intramembranous ossification
What is formed via intramembranous ossification?
Intramembranous bones are always flat bones. Parts of the skull, mandible and the maxilla are all considered to be intramembranous bones.
What does Intramembranous ossification produce?
it produces the flat bones of the skull and most of the clavicle (collarbone)
Cranial bones and other flat bones develop?
The calvaria including the parietal, frontal, temporal,and occipital bones form by intramembranous ossification. The skull base develops via endochondral ossification.
What are the two types of ossification?
Intramembranous and Endochondral Ossification
Bones of the skull and clavicle develop by?
The clavicles and the cranial bones of the skull develop from a fibrous membrane. This process is known as intramembranous ossification.
What type of ossification occurs in the roof of the skull?
Intramembranous ossification
Does endochondral ossification begins on fibrous connective tissue membranes?
No, INTRAMEMBRANOUS OSSIFICATION, is developed from a fibrous membrane. Essentially all bones below the base of the skull (except the clavicles) are formed from endochondral ossification. Endochondral ossification uses hyaline cartilage "bones" as a pattern for forming true bones.
Intramembranous ossification begins with what cells?
Intramembranous ossification begins when osteoblasts differentiate within a mesenchymal or fibrous connective tissue.
When does a soft callus form?
intramembranous ossification
