What is the corpus callosum's purpose?
Connects the two brain hemispheres and carrying messages between them.

What is the endocrine system?
The body’s “slow” chemical communicator system.
What's the difference between the left hemisphere and the right hempishere?
Left - associated with logic, systematic thinking, and production of speech.
