trigeminal nerve Flashcards
monitor changes occuring inside and outside the body
sensory
interprets sensory input and make decision on what should be done at each moment
integration
it exerts the effects
organs, muscles, glands
it is the largest cranial nerve
trigeminal nerve
how many diviisons are purely sensory
2
wholly sensory and intermediate division of the trigeminal nerve
maxillary division
what are the 4 main branches of the maxillary division
facial, infrarbital, pterygoplatine region, cranium
cranium branches to
middle meningeal branch
3 branches of the pterygopalatine ganglion
zygomatic, pterygopalatine ganglion, PSAN
zygomatic branch is subdivided into
zygomaticotemporal and zygomaticofacial
the pterygopalatine ganglion is usbdivided into
orbital, nasal, pharyngeal, lesser and greater palatine
convey senosry impulses from the periosteum of orbit
orbital branch
innervates the nasopharynx
pharyngeal branch
innervates mucuous membrane of premaxilla
nasal branch, nasopalatine nerve
where does the nasopalatine nerve come out
nasopalatine foramen
landmark of nasopalatine foramen
incisive papilla
what does the greater palatine nerve innervate
hard palate
lesser palatine nerve inneravates the soft palate T or F
T
posyerior superior alveolar artery innervates
maxillary molars except mesiobuccal root of mx 1st molar
it innervates the maxillary premolars and the mesiobuccal root of mx 1st molar
Middle superior alveolar nerve
infraorbital region is divided into
MSAN and ASAN
IT PROVIDES SENSORY INNERVATION TO MAXILLARY CANINES AND INCISORS
ASAN anterior superior alveolar nerve
what nerve should be anesthethize if yu are going to extract the mandibular 2nd molar
inferior alveolar nerve
what nerve innervates the mandibular premolars
mental nerve
incisive nerve innervates
the mandibular incisors and canines
tic doloureux is also known as
trigeminal neuralgia
it is a paroxysmal intermitent excrutiating pain confined to one branches of the trigeminal nerve
trigeminal neuralgia
trigeminal neuralgia is unilateral t or f
t
etiology of trigeminal neuralgia
viral lesion in the ganglion, blood vessels compressing on the nerve, demyelination of the nerve
2 arteries that impinge the nerve
SCA- superior cerebellar artery and AICA- anterior inferior cerebellar artery
opioids can be given first before NSAIDS t or f
f- nsaids must be given first
what are the solutions of trigeminal neuralgia
neurectomy, cryotherapy, microvasculature nerve root decompression surgery
tefflon pad is used to separate the nerve and blood vessel
microvasculature nerve root decompression surgery
effects of lingual nerve injury
loss of taste, tingling sensation, altered taste
freys syndrome is due to
auriculotemporal nerve injury
