What is the relationship between osteoclasts and osteoblasts?
Osteoblasts build bones, and osteoclasts clean up excess bones. They keep each other in balance.
Osteoblasts blow up your skeleton. Osteoclasts put bones into casts. Death is inevitable.
Osteoblasts rule the skeletal system with an iron fist. Osteoclast seek to usurp the power of the mighty calcium lords. There is a war. One day it will end.
Everything changed when the osteoclasts attacked. Now it's up to the last osteoblast to save the day.
