Lab #9 Flashcards
descending palatine artery identification
descends from maxillary artery within pterygopalatine fossa; divides into greater and lesser palatine arteries
descending palatine artery supplies
gives off branches to palate
descending palatine artery bony landmark
palatine canal
greater palatine artery identification
anterior branch from descending palatine artery; travels anteriorly on hard palate
greater palatine artery supplies
hard palate posterior to canines
lesser palatine artery identification
posterior branch from descending palatine artery; travels posteriorly to soft palate
lesser palatine artery supplies
soft palate and palatine tonsil
infra-orbital artery identification
superiorly from maxillary artery to enter inferior orbital fissure; travels with infra-orbital nerve
infra-orbital artery supplies
skin of maxillary cheek, lower eyelid, upper lip, and lateral nose
infra-orbital artery bony landmark
inferior orbital fissure to infra-orbital groove, canal, and foramen
sphenopalatine artery identification
terminal branch of maxillary artery; gives rise to posterior lateral nasal and posterior septal branches; will likely be cut (look for lumen)
sphenopalatine artery supplies
gives off branches to lateral nasal wall and nasal septum
sphenopalatine artery bony landmark
sphenopalatine foramen to nasal cavity
greater palatine artery bony landmark
greater palatine foramen
lesser palatine artery bony landmark
lesser palatine foramen
nerve of pterygoid canal identification
inferior to CN V2 and posterior to pterygopalatine ganglion; along inferior wall of sphenoid sinus
nerve of pterygoid canal supplies
autonomics to pterygopalatine ganglion (deep petrosal and greater petrosal nerves merge at nerve of pterygoid canal)
nerve of pterygoid canal bony landmark
pterygoid canal
greater palatine nerve identification
descends from pterygopalatine ganglion and goes anteriorly toward hard palate
greater palatine nerve supplies
mucosa of hard palate and gingiva posterior to canines
greater palatine nerve bony landmark
greater palatine foramen
lesser palatine nerve identification
descends from pterygopalatine ganglion and goes posteriorly toward soft palate
lesser palatine nerve supplies
mucosa of soft palate, uvula, and palatine tonsil
lesser palatine nerve bony landmark
lesser palatine foramen
posterior superior alveolar nerve identification
last branch of CN V2 before inferior orbital fissure; descends toward maxillary sinus
posterior superior alveolar nerve supplies
maxillary molars + gingiva (EXCEPT MB root of 1st molar); maxillary sinus
posterior superior alveolar nerve bony landmark
PSA foramen
infra-orbital nerve identification
travels posterior to anterior through superior part of maxillary sinus
infra-orbital nerve supplies
skin over maxillary cheek, lower eyelid, upper lip, and lateral nose
infra-orbital nerve bony landmark
infra-orbital groove, canal, foramen
middle superior alveolar nerve identification
branches off infra-orbital nerve; goes within lateral wall of maxillary sinus
middle superior alveolar nerve supplies
MB root of 1st maxillary molar and premolars + gingiva; maxillary sinus
middle superior alveolar nerve bony landmark
roots of maxillary premolars
anterior superior alveolar nerve identification
proximal to infra-orbital foramen; branches off infra-orbital nerve; goes within anterolateral wall of maxillary sinus
anterior superior alveolar nerve supplies
incisors, canines, + gingiva; maxillary sinus
anterior superior alveolar nerve bony landmark
roots of canines/incisors
CN V2 identification
travels posterior to anterior through superior part of pterygopalatine fossa
CN V2 bony landmark
foramen rotundum
