What is a "facial nerve"?

A facial nerve is a vital cranial nerve that plays a crucial role in controlling the muscles of facial expression. It is responsible for transmitting signals that allow us to smile, frown, blink, and make various facial expressions. Additionally, the facial nerve carries sensory information related to taste from the anterior two-thirds of the tongue. This intricate network of nerve fibers ensures proper facial muscle coordination and facilitates communication between the brain and facial structures.

3. A tiny twig of the facial nerve, the one to the muscles of her mouth, has been severed.
