Mandibular Nerve (V3)

Front 1

where does the mandibular nerve pass through on the skull?

Back 1

foramen ovale

Front 2

what are the three branches of the MAIN TRUNK of the mandibular nerve?

Back 2

1)meningeal nerve
2) tensor tympani nerve
3) tensor veli palatini nerve

Front 3

meningeal nerve

Back 3

re-enters the skull through foramen spinosum and supplies the dura

Front 4

tenor tympani nerve

Back 4

supplies ear

Front 5

tensor veli palatini

Back 5

tenses palate for swallowing

Front 6

function of the Anterior Division of the mandibular nerve?

Back 6

provides motor supply to the true muscles of mastication and sensory supply via the bucal nerve

Front 7

what does the BUCCAL NERVE do?

Back 7

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)

Front 8

Branches of the POSTERIOR DIVISION of the mandibular nerve

Back 8

1) lingual nerve
2) inferior alveolar nerve
3) auriculotemporal nerve

Front 9

lingual nerve (SENSORY!)

Back 9

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.

Front 10

inferior alveolar nerve (SENSORY portion)

Back 10

sensory to lover teeth
terminates as mental nerve

Front 11

inferior alveolar nerve (MOTOR portion)

Back 11

mylohyoid nerve, which innervates the mylohyoid and digastric muscles

Front 12

auriculotemporal nerve (SENSORY)

Back 12

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)
