, It is also known as the ninth cranial nerve
,cranial nerve IX or simply CN IX ,is a cranial
nerve that exits the brainstem from the sides of
the upper medulla ,just anterior (closer to the
nose) to the vagus nerve . Being a mixed nerve
(sensorimotor),it carries afferent sensory and
efferent motor information . The motor division
of the glossopharyngael nerve is derived from
the basal plate of the embryonic medulla
oblangata, whereas the sensory divion
originates from the cranialneural crest
