Introduction: The facial nerve is the seventh cranial nerve of the peripheral nervous system that is the chief motor nerve of the face. It exits the brainstem between the pons and the medulla. The primary motor function is the control of the muscles of facial expressions and conveys impulses of taste sensations from the anterior two-thirds of the tongue and mouth. It also supplies many of the glands of the head and neck. Without the facial nerve, a person could not show facial expressions, cry, wink, smile, or frown. The facial nerve serves several functions and any damage to them can cause many or all of …show more content…

Discussion: Testing of the facial nerve through the different types of facial expressions will prove to be difficult to perform if an individual is suffering from facial nerve damage. These tests will allow all the muscles in the face to be used. Any asymmetry of the face would also prove difficult to perform the facial expressions because paralysis already exists and the muscles would be hard to control. As the data shows, I do not have difficulty performing any of the facial expressions or taste test.
Conclusion: Although, these results reflect that there are no obvious signs of facial nerve damage, a diagnosis of a person’s medical and family history should be taken into consideration. Also, all of the 12 cranial nerves of the system are involved in the function and sensory of the facial nerve should be tested for a more accurate diagnosis of nerve damage.
