      Cellular biology always reminds me how crazy animals are; how much time and how many generations animals must have taken to get here. Its awesome there’s just cells that show up, get supplied everything they need and build mineral deposits. And a fully separate cell type to deconstruct those.

        It’s a robust system: when a bone is fractured and not straightened before healing, it will eventually get close to the right shape.

        Fraggle Rock helped me understand this part of cell bio (osteoclasts/blasts).

        In the underground caverns of your skeleton, a perfect symbiotic ecosystem exists between two distinct groups: the Osteoblasts (the Doozers) and the Osteoclasts (the Fraggles). Just as in Fraggle Rock, their survival depends on a continuous cycle of building and eating, ensuring the structural integrity of their world

        Like the industrious Doozers, osteoblasts are obsessed with construction.

        The osteoclasts are the carefree Fraggles of this system. They roam the bone surface looking for old, damaged, or unnecessary structures to “snack” on.
