WHEN BABY IS IN ITS MOTHER'S UTERUS, A TOUGH, FLEXIBLE MATERIAL CALLED CARTILAGE BEGIN TO FORM WHERE HARDER BONES EVENTUALLY GROW. AS THE BABY GROWS, CARTILAGE IS CONTINUALLY REPLACES WITH BONE IN A PROCESS CALLED OSSIFICATION. THIS TAKES PLACE IN THE SHAFTS AND HEADS OF ALL BONES. ONCE HARDENED, YOUR BONES CONTINUE TO LENGHTEN UNTIL YOU ARE ABOUT 20 YEARS OLD.

AT THE AGE OF AROUND 20 YEARS, BONE GROWTH IS COMPLETE. HOWEVER, SOME FACE BONES, LIKE THE NOSE AND LOWER JAW BONES, CONTINUE TO GROW VERY SLIGHTLY AT ALL AGES. ONCES FULLY GROWN, BONES ARE BEING REPAIRED CONTINUALLY.
