Bone Remodeling

Bone remodeling is the continuous process through which old bone tissue is replaced by new bone tissue, maintaining the strength and integrity of the skeletal system.

Endochondral Ossification

The process by which bone tissue is formed from cartilage, a crucial mechanism in the development of the fetal skeleton into the mature bones of an adult.

Intramembranous Ossification

A process by which flat bones, such as those of the skull, are formed directly from mesenchymal tissue without a cartilage model.

Appositional Growth

A process of growth where new layers of tissue are added to the surface of an organ or bone, leading to an increase in diameter.
