Until adulthood the long bones, elongated bones in the fingers, arms, legs and hips grow quickly by expanding at each end. These growth centers contain gristle-like-cartilage cells that create layer upon layer of new bone tissue. Once the cartilage cells stop dividing, the growth centers harden into bone, marking the end of growth in that region.
Most growth centers, such as those in the femur and tibia of the leg, have ossified by the age of 17 to 20 years. The breastbone is one of the last bones to stop growing, around 25.
I have question for all 0f you: ”How does the body know when to stop growing any parts of itself?”
I welcome your feedbacks!
Amazing isn’t it?
