What Causes Bell's Palsy?
Reviewed: Dr. Gromatzky
Human beings have a very complex language system. Not only do we communicate with each other vocally, but we also communicate a lot with each other using visual language. This includes movements with our various body parts, and with different movements of our faces.
There are 43 muscles in our faces that help us to pull a number of facial expressions. These muscles are controlled by the seventh cranial nerve that passes through a narrow corridor on its way to our face. If something were to cause an issue with this nerve then we could lose control of our face muscles.
