You may have heard that your nose and ears never stop growing. As you get older, you might notice that your nose looks bigger or your earlobes look longer than they did when you were younger. Is there any truth to the idea that they are still growing?
As we age, our nose and our ears do get bigger, but not because they are growing. The real reason is a common scientific force known as GRAVITY. You see, our nose and our ears are made of cartilage and while many people mistakenly believe that cartilage never stops growing, the fact is cartilage does stop growing. However, cartilage is made of collagen and other fibers that begin to break down as we age.
The only human body part that does not grow after birth is the ossicular chain, which is composed of three small bones and is located in the middle ear.
These bones are also the smallest lightest bones in the human body. Each bone is smaller than a grain of rice. The stapes is the smallest and is only 2.8 millimeters or 0.11 inch long.
