Appositional Bone Growth
The growth in diameter of bones around the diaphysis occurs by deposition of bone beneath the periosteum. Osteoclasts in the interior cavity continue to degrade bone until its ultimate thickness is achieved, at which point the rate of formation on the outside and degradation from the inside is constant.

Famous quotes containing the words bone and/or growth:
“You must be wise, in order to sniff out and weigh these mighty books, and swift in the hunt and brave in the battle; then, by careful reading and frequent reflection, crack open the bone and suck out the substantific marrow.”
—François Rabelais (1494–1553)
“But parents can be understanding and accept the more difficult stages as necessary times of growth for the child. Parents can appreciate the fact that these phases are not easy for the child to live through either; rapid growth times are hard on a child. Perhaps it’s a small comfort to know that the harder-to-live-with stages do alternate with the calmer times,so parents can count on getting periodic breaks.”
—Saf Lerman (20th century)
