  • Front
  • Back
where does the mandibular nerve pass through on the skull?
foramen ovale
what are the three branches of the MAIN TRUNK of the mandibular nerve?
1)meningeal nerve
2) tensor tympani nerve
3) tensor veli palatini nerve
meningeal nerve
re-enters the skull through foramen spinosum and supplies the dura
tenor tympani nerve
supplies ear
tensor veli palatini
tenses palate for swallowing
function of the Anterior Division of the mandibular nerve?
provides motor supply to the true muscles of mastication and sensory supply via the bucal nerve
what does the BUCCAL NERVE do?
pierces the buccinator muscle, but does NOT innervate its movement!!!!! (DIFFERENT THAN BUCAL BRANCH OF THE FACIAL NERVE, which supplies motor function to the buccinator)
Branches of the POSTERIOR DIVISION of the mandibular nerve
1) lingual nerve
2) inferior alveolar nerve
3) auriculotemporal nerve
lingual nerve (SENSORY!)
innervates anterior 2/3 of tongue
carries taste fibers from FACIAL NERVE (from chorda tympani)
-also carries preganglionic parasympathetic fibers from FACIAL NERVE which go to submandibulare gangion and then to the submandibular and sublingual glands.
inferior alveolar nerve (SENSORY portion)
sensory to lover teeth
terminates as mental nerve
inferior alveolar nerve (MOTOR portion)
mylohyoid nerve, which innervates the mylohyoid and digastric muscles
auriculotemporal nerve (SENSORY)
innervates skin of auricle and the TMJ.

-carries postganglionic parasympathetic fibers from the otic ganglion to the parotid gland. (parasympathetic innervation is through CN IX- glossopharyngeal)
