A&P: Bone Cells and Development

What are osteoblasts?

bone forming cells found in areas of high metabolism within the bone.

What are osteocytes?

mature bone cells that develop from osteoblasts and help maintain healthy bone tissue by secreting enzymes and controlling calcium release into the bloodstream.

What are osteogenic cells?

respond to trauma by giving rise to osteoblasts (bone forming cells) and osteoclasts (bone destroying cells).

What are bone-lining cells?

Developing from osteoblasts, located along the surface of most adult bones and regulate the movement of calcium and phosphate into and out of the bones

What are osteoclasts?

large, multinucleate cells that develop from hematopoietic stem cells and are located at sites of bone resorption; they break down bone tissue and are important for growth, healing, and remodeling.

What is ossification?

the process by which bones form in embryos and, in adults, refers to the process of bone remodeling and repair.

What is endochondral ossification?

the replacement of hyaline cartilage with endochondral bone.

What is intramembranous ossification?

the development of fibrous membranes into membrane bones.
