Card Set Information
What are the branches of the maxillary artery?
- Superior Alveolar Artery
- Inferior Alveolar Artery
- Middle meningeal artery
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
-Preganglionic parasympathetic neurons from CN 9 exit the middle ear as the
lesser pretrosal nerve
, go through foramen ovale and synapse on
-Postganglionic parasympathetic neurons then provide visceral motor innervation to
Mandibular branch of trigeminal (CN 5) gives off:
1. Buccal nerve
2. Inferior alveolar nerve
3. Lingual nerve
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.
-Found on side ipsilateral to injury
What are the 4 cranial nerves that carry visceral
innervation to the head?
