  1. What are the branches of the maxillary artery?
    • - Superior Alveolar Artery
    • - Inferior Alveolar Artery
    • - Middle meningeal artery
    • - Infraorbital
    • - Sphenopalatine
  2. Chorda tympani nerve
    • CN XII (facial, 7)
    • -Joins with lingual nerve
    • -Provides special sensory taste to anterior 2/3 of tongue
    • -Visceral motor parasympathetic innervation to submandibular and sublingual salivary glands
  3. Otic Ganglion
    • -Preganglionic parasympathetic neurons from CN 9 exit the middle ear as the lesser pretrosal nerve, go through foramen ovale and synapse on otic ganglion.
    • -Postganglionic parasympathetic neurons then provide visceral motor innervation to parotid gland.
  4. Mandibular branch of trigeminal (CN 5) gives off:
    • 1. Buccal nerve
    • 2. Inferior alveolar nerve
    • 3. Lingual nerve
  5. Horner's Syndrome.

    Presentation and reason for signs/symptoms?
    • -Ptosis (drooping of upper eyelid) : Results from loss of sympathetic innervation to the superior tarsal muscle.
    • -Anhidrosis (decreased sweating): results from loss of sympathetic innervation to sweat glands
    • -Miosis (constricted pupil): Results from loss of sympathetic innervation to dilator pupillary muscle.
    • -Flushed face.
    • -Found on side ipsilateral to injury
  6. What are the 4 cranial nerves that carry visceral parasympathetic innervation to the head?
    3,7,9,10
