Bone Remodeling: Osteoblasts, Osteocytes, Osteoclasts
Captions available
The idea
Bone remodels continuously through three cell types: osteoblasts deposit new bone matrix, osteocytes maintain it once surrounded, and osteoclasts break bone down to release stored calcium.
In practice
Osteoblasts that become trapped in their own matrix settle into a reduced metabolic state as osteocytes.
Where people slip
Bone strength depends on both matrix components — organic material resists breaking, mineral material resists bending.
