III. Physiology

  1. Sensory for pain, touch and Temperature
    1. Mucosa of pharynx, fauces, and Palatine Tonsil
  2. Taste Sensation for posterior third of Tongue
  3. Motor with CN 9 to pharynx

IV. Anatomy

  1. Nucleii in Medulla
    1. Somatic Motor Nucleii
      1. Nucleus Ambiguous transmits signals for swallowing
    2. Visceral Motor Nucleii
      1. Inferior Salivatory nucleus innervates Parotid Gland (via otic Ganglion)
    3. Visceral Sensory Nucleii
      1. Nucleus Solitarius transmits taste signals from posterior third of Tongue
      2. Also transmits signals from carotid body and carotid sinus
    4. Somatic Sensory Nucleii
      1. Spinal Nucleus of CN 5 transmits signals from External Ear and posterior third of Tongue
  2. Course
    1. Starts in one of four nucleii in the Medulla (see above)
    2. Passes through jugular foramen of skull
      1. Accompanied by CN 10 and CN 11
    3. Follows Internal Carotid Artery
    4. Passes under styloid process and then into pharynx
    5. Synapses at superior ganglia and inferior ganglia

V. Exam

  1. Done concurrently with Exam of CN 10

Ontology: Glossopharyngeal nerve structure (C0017679)

Definition (MSH) The 9th cranial nerve. The glossopharyngeal nerve is a mixed motor and sensory nerve; it conveys somatic and autonomic efferents as well as general, special, and visceral afferents. Among the connections are motor fibers to the stylopharyngeus muscle, parasympathetic fibers to the parotid glands, general and taste afferents from the posterior third of the tongue, the nasopharynx, and the palate, and afferents from baroreceptors and CHEMORECEPTOR CELLS of the carotid sinus.
Definition (NCI_CDISC) The ninth cranial nerve.
Definition (NCI) The ninth cranial nerve. It originates in the brainstem and passes through the jugular foramen. It has motor and sensory functions that relate to the tongue, pharynx and middle ear.
