**The facial nerve** is one of the main nerves in the human body, which is responsible for transmitting signals from the brain to the facial muscles and facial skin. This nerve is an important tool for maintaining mobility and expressing emotions in the face. It begins at the base of the brain and passes through the cerebellum, where it divides into the vestibular-cochlear and vestibular-frontal nerves. The facial nerve then makes a sharp turn as it passes through the piriformis canal and reaches its destination at the bottom of the skull, where the wing of the visceral bone is located.
Having entered the face, the facial nerves enter the large masticatory muscles and spread throughout the face through the facial muscles. The function of the facial nerve is to provide motor messages and control the myocardial facial muscles. Thus, it controls many important processes such as the movement of the eyes, ears, lips, cheeks, tongue and neck.
