Glossopharyngeal nerve

The glossopharyngeal nerve is the ninth (IX) of twelve pairs of cranial nerves (24 nerves total). It exits the brainstem out from the sides of the upper medulla, just rostral (closer to the nose) to the vagus nerve.

    Facial nerve

    The facial nerve is the seventh (VII) of twelve paired cranial nerves. It emerges from the brainstem between the pons and the medulla, and controls the muscles of facial expression, and taste to the anterior two-thirds of the tongue. It also supplies preganglionic parasympathetic fibers to several...

They supply the skin and conjunctiva of the lower eyelid, joining at the lateral angle of the orbit with the facial and zygomaticofacial nerves. This article was originally based on an entry from a public...

It sometimes receives a filament from the trochlear nerve, but this is possibly derived from the branch which goes from the ophthalmic to the trochlear nerve. It passes forward in a separate tube of dura mater, and enters...
