It seems like these holding areas are a very important part of what keeps the body running.
Something as simple as the osseous ampullae in the ear is an amazing piece of engineering.
Not only is hearing itself an amazing feat, it is designed with this amazing construct. It has a protective system consisting of ear wax and hairs that prevent attack from the outside. A simple but effective shield.
On top of all this the osseous ampullae acts as a type of gyroscope to keep you balanced.
This is just one tiny area in the ear and each person has two of these hard working tools. Amazing.
