Did You Know!
Cartilage Was the “Blueprint” for Most of Your Skeleton Before Birth
Rare Fact: Most of your bones started as cartilage models in the womb.
Why this matters:
During development, a process called endochondral ossification slowly replaces cartilage with bone. Even after birth, growth plates at the ends of long bones remain cartilage until adolescence — which is how children grow taller.
Interesting twist: Once those growth plates harden into bone, height growth permanently stops.
