nerves Flashcards
branches of trigeminal nerve
ophthalmic
maxillary
mandibular
what makes of the trigeminal ganglion
foramen ovale and foramen rotundum
maxillary nerve branches
pterygopalatine n.
posterior superior alveolar n.
infrorbital n.
zygomatic n.
maxillary n > pterygopalatine n. > what are the branches
greater/descending anterior palatine n.
nasopalatine n.
middle/posterior/lesser palatine n.
passes through superior orbital fissure
ophthalmic n.
innervates skin of nose and forehead
ophthalmic n.
passes through foramen rotundum
maxillary n.
branches off of maxillary nerve within pterygopalatine space
pterygopalatine n.
passes along nasal septum in nasal passageway to pass through incisive canal
nasopalatine n.
innervate front of palate
nasopalatine n
innervates posterior portion of hard palate
greater palatine n.
splits off within pterygopalatine fossa/space; passes through alveolar canal openings into maxillary sinus
PSA
innervates pulp of maxillary molars except mesiobuccal root of first maxillary molar
PSA
maxillary n. > infraorbital n branches
MSA
ASA
terminal branches
branch splits off maxillary nerve while in the infraorbital groove
infraorbital n.
passes along the wall of the maxillary sinus to the pulp of maxillary premolars and mesiobuccal root of maxillary 1st molar
MSA
through maxillary sinus and trabecular bone to the pulp of maxillary anterior teeth
ASA
after existing from infraorbital foramen, split off to supply upper lip, side of nose and lower eyelid as well as tissue next to premolars and anteriors
terminal branches of infraorbital nerve
exits thru foramen ovale, giving both sensory and motor innveration
mandibular nerve
branches of mandibular n
auriculotemporal n.
buccinator nerve (long buccal)
Lingual nerve
Inferior Alveolar nerve
passes thru infratemporal fossa to the tissue in the cheek above the buccal shelf next to molars and premolars, extends to the corner of the mouth
buccinator nerve
passes near mylohyoid line to innervate tissue of the floor of the mouth and sensory to anterior 2/3 of tongue (not taste)
lingual nerve
enters the mandbular canal opening to enter the pulp and innervate mandibular posterior teeth
inferior alveolar nerve
branches of inferior alveolar nerve
mental n
incisive n
mylohyoid n
branches before entering the mandibular foramen and passes in the mylohyoid groove to muscles in the floor of the mouth
mylohyoid n
the terminal branch of the inferior alveolar nerve exiting the mandibular canal thru the mental foramen to innverate the chin and lower lip
mental nerve
terminal branch of inferior alveolar nerve that continues within the mandibular canal to enter the pulp of the mandibular anterior teeth
incisive nerve
passes to TMJ and skin over lateral skull
auriculotemporal n.
facial nerve (VII) passes from the brain thru the __ of the temporal bone and exits the skull thru the _
internal acoustic meatus
stylomastoid foramen
supply taste to the anterior 2/3 of tongue
facial nerve (VII)
supply taste and general sensation to the posterior 1/3 of tongue
glossopharyngeal nerve (IX)
exits skull thru jugular foramen
glossopharyngeal nerve (IX)
controls motor/efferent impulses to all muscles of tongue
hypoglossal nerve (XII)
exits cranium thru hypoglossal canal found on the walls of the foramen magnum
hypoglossal nerve (XII)
motor/efferent branches innervate the muscles of facial expression and control secretion of submandibular and sublingual glands
facial nerve (VII)
