GENERAL HISTOLOGY

Detailed explanation-1: -Bone ossification, or osteogenesis, is the process of bone formation. This process begins between the sixth and seventh weeks of embryonic development and continues until about age twenty-five; although this varies slightly based on the individual.

Detailed explanation-2: -There are two major modes of bone formation, or osteogenesis, and both involve the transformation of a preexisting mesenchymal tissue into bone tissue. The direct conversion of mesenchymal tissue into bone is called intramembranous ossification. This process occurs primarily in the bones of the skull.

Detailed explanation-3: -Intramembranous ossification forms the flat bones of the skull, mandible and hip bone.
