Facial nerve is the seventh cranial nerve and is the nerve of facial expression.
It affects only one side of the face at a time, causing it to droop or become stiff on that side." This medical condition is caused by excessive trauma to the seventh cranial nerve, also called the "facial nerve." This results in miscommunication between the brain stem and the muscles on either side of the patient's face, causing the latter to stop responding to neurological signals.
