Your patient recently had a viral infection and now she cannot move the muscles on the right side of her face. In addition, she is experiencing a loss of taste and dry mouth and she cannot close her right eye. Which cranial nerves have been affected by the viral infection?
Listed below are the cranial nerves that have been affected by the viral infection:
-
The cranial nerve that had affected muscles on the right side of her face:
-
Facial (Cranial nerve VII): control of muscles of facial expression
-
The cranial nerve that had affected loss of taste:
-
Facial (Cranial nerve VII): fibers from the anterior two-thirds of tongue
-
Glossopharyngeal (Cranial nerve IX) : fibers from posterior one-third of tongue.
-
Vagus (Cranial nerve X): fibers to the epiglottis.
-
The cranial nerve that had affected dry mouth:
-
Glossopharyngeal (Cranial nerve IX): Secretion of saliva
-
Facial (Cranial nerve VII): Secretion of saliva
-
The cranial nerve that had affected closing of the right eye:
-
Facial (Cranial nerve VII) : Control of facial expression
-
Oculomotor (Cranial nerve III) : Movement of eyeballs and upper eyelid.
