ANATOMY

Detailed explanation-1: -Intramembranous ossification involves the replacement of sheet-like connective tissue membranes with bony tissue. Bones formed in this manner are called intramembranous bones. They include certain flat bones of the skull and some of the irregular bones. The future bones are first formed as connective tissue membranes.

Detailed explanation-2: -Intramembranous ossification is the characteristic way in which the flat bones of the skull and the turtle shell are formed. During intramembranous ossification in the skull, neural crest-derived mesenchymal cells proliferate and condense into compact nodules.

Detailed explanation-3: -Flat bones [like those of the calvarium (skull) and the scapula] and foci of woven bone are formed by intramembranous ossification. In this process, bone is laid down directly in the mesenchymal collagenous matrix rather than by transmutation of a preformed cartilage model.

Detailed explanation-4: -Intramembranous ossification is the process of bone development from fibrous membranes. It is involved in the formation of the flat bones of the skull, the mandible, and the clavicles.

Detailed explanation-5: -What are examples of intramembranous ossification? Flat bones from the skull, the pelvis, and the clavicles develop from the intramembranous ossification process, which differentiates the mesenchymal tissue into compact bone.
