State
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.
Show
Osteoblasts that become trapped in their own matrix settle into a reduced metabolic state as osteocytes.
Watch for
Bone strength depends on both matrix components — organic material resists breaking, mineral material resists bending.
