  2. BRAIN EXIT OF THE CRANIAL NERVES

  3. GLOSSOPHARYNGEAL NERVE IX.

  4. GLOSSOPHARYNGEAL NERVE IX. LEAVES THE SKULL THROUGH THE JUGULAR FORAMEN. THE FIST BRANCH – TYMPANIC NERNE ORIGINATES IN THE PETROSAL FOSSULA IT HAS TWO SENSORY GANGLION: SUPERIOR (JUGULAR) AND (PSEUDOUNIPOLAR CELLS) INFERIOR (PETROSAL)

  5. NUCLEI OF GLOSSOPHARYNGEAL NERVE: ambiguusnucleusSVM inferiorsalivatorynucleusGVM nucleus of thesolitarytractSVS nucleus of thespinaltrigeminaltr. GSS

  6. Sensoryganglia of theglossopharyngealnerve PETROSAL GANGLION (INFERIOR) JUGULAR GANGLION (SUPERIOR) Vegetative (parasympathetic) ganglion: OTIC GANGLION

  7. GLOSSOPHARYNGEAL NERVE INNERVATES WITH SOMATOSENSORY FIBERS:posterior 1/3 of thetongue palatinetonsil WITH SPECIAL VISCEROSENSORY FIBERS: tastebuds of thecircumvallatepapillas WITH GENERAL VISCEROSENSORY FIBERS: mucousmembrane of thepharynx receptors of thecarotid sinus WITH GENERAL VISCEROMOTOR (parasympathetic) FIBERS: parotidgland WITH SPECIAL VISCEROMOTOR FIBERS: levatorvelipalatinimuscle stylopharyngeusmuscle constrictormuscles (pharyngealplexus)
