Bone Cells - Anatomy Quiz

3 primary cells types in the bone

- osteocytes
- osteoclasts
- osteoblasts

osteocytes

- mature bone cells
- recycle calcium in the bones

osteoclasts

- GIANT cells with sot nuclei
- moves over the bone dissolving the bony matrix
- this releases calcium and phosphate into the body
- REMOVES matrix

osteoblasts

- produce new bones through osteogensis
- help add calcium to the bony matrix
- ADD matrix

acroynm for bone growth

BCPDE (Bones can pop during exercise)
- bone collar
- cavities
- periosteal
- diaphysis
- epiphyseal line

bone collar

A bone collar made of calcium forms around the cartilage

Cavities

Cavities begin to form within the bone as the cartilage continues to clacify. This leaves room for blood vessels

Periosteal

A periosteal bud forms which begins the flow of nutrients to the bone. This allows spongy bone to form.

diaphysis

The addition of nutrients allows the diaphysis to elongate and form areas for the bone marrow.

epiphyseal line

The epiphyseal line forms and the bone continues to elongate from these points until it has reached its full growth.

What happens when a bone is fractured?

- blood vessels are broken
- A fracture hematoma developes
- A callus forms
- Osteoblasts and new bone cells until the area is repaired
