Smallest Bone in Human Body

Have you ever wondered what is the smallest bone in the human body? Perhaps you’ve read about it before, but if you don’t know, no need to worry – we got the answer right here.

Every human’s smallest bone is called the stapes, and it is one of the three bones that make up your middle ear. It is shaped like the letter “U”.

The primary function of this bone is to receive sound vibrations and pass them along, so they can eventually be processed by the brain. It measures roughly 0.1 inch (2.5 millimeters).

We mentioned before that the stapes is one of the three bones that make up the middle ear, but it may be interesting to note that the other two bones - the anvil and the hammer are second and third smallest bones in the body.
