The facial nerves, also known as cranial nerve VII, are a pair of nerves that control the muscles of facial expression. They originate in the brainstem and travel through the skull to reach the face. These nerves are responsible for movements such as smiling, frowning, and blinking, allowing for a wide range of facial expressions. In addition to motor functions, the facial nerves also carry sensory information from the taste buds on the front two-thirds of the tongue. They play a role in the sensation of taste and are involved in the secretion of saliva and tears, contributing to overall facial and oral health.
