What's that? What's it do?

This is the first in a series that will pick a single part of the brain and explain its function. As the first I will pick the most obvious one, THE CEREBRUM!

The cerebrum is not the brain itself, although the word comes from the latin "the brain" or "the understanding", but is the largest part of the brain. It has two cerebral hemispheres that are constituted of: cerebral cortices, basal nuclei, and the limbic system. Together, with your cerebellum, it coordinates and executes every conscious task you ever do.

It is easily one of the most important structures, not just in your brain, but in your body.
