Which body part does not grow from birth: The eyeball is the only organism that does not grow from birth. It is fully grown when you are born. When you look at a baby’s face, so see mostly iris and little white. As the baby grows, you get to see more and more of the eyeball.

Human development, the process of growth and change that takes place between birth and maturity.

Human growth is far from being a simple and uniform process of becoming taller or larger. As a child gets bigger, there are changes in shape and in tissue composition and distribution. In the newborn infant, the head represents about a quarter of the total length; in the adult, it represents about one-seventh.

At some point in your life, someone has probably shared with you a little nugget of wisdom about how our nose and our ears never stop growing.

You might then look around and see a bunch of senior citizens and notice that, in fact, their facial appearance is slightly larger than their younger counterparts and believe this fact to be true…but is it?

Make a wild guess and see if you can answer correctly which part of the body don’t increase in size with age!

A common misconception is that the eyes do not grow from infancy. However, the human eye grows about one-third in size. At birth, the eyeball is 16 millimetres wide, but it grows to 23 millimetres in width by the age of 3 years. Eyes reach their maximum size at puberty, growing to be approximately 24 millimetres wide each.

We all know that the human body grows in size since a child is born. But there is a part of the body that remains of the same size. The size that it had at the time of birth!

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 millimetres or 0.11 inches long.

The growth of most structures(muscles, bones etc…) of the human body stops after adolescence. But here is one special structure called cartilage that continues to grow till death. Also, one important point to mention is that cartilage is present at several sites in our body but mainly the cartilage(softer connective tissues) of the ear and nose continue to grow. That’s why aged people have larger ears and noses comparatively.

Final Thoughts

The only part of the human body which does not grow in size from birth to death is the ‘innermost ear ossicle’ or the ‘Stapes’.

The stapes is 3 mm in size when a person is born. As a person grows or develops, this ossicle does not grow in size.

However, thinning of the stapes has been heard of. In fact, it is the thinning of the stapes or the malfunction of the stapes that result in ear problems and deafness.

Your eyes. When you are born, the eyes you are born with are the same size they will be for the rest of your life. While they may change slightly in color or deteriorate, causing the need for glasses/contacts, they never grow.
