oral Flashcards
what positions food on occlusal surfaces
buccinator and tongue
what nn and vessels may be found in the mandiblar foramen
inf alveolar nn and Aa/Vv
what nn innervates the intrinsic mm of the tongue
CN 12, hypoglossal
lymph drainage of the oral region
typically down and in to the int jugular, crossover may occur to the submandibular lymph nodes but not always
free, attached gingiva and alveolar mucosa
free: not attached to underlying bone, most coronal
attached: firmly attached to underlying bone
alveolar mucosa: superficial to the alveolar bone
inn of the max teeth
ALL BRANCHES OF CNV2
incisors and canine: anterior sup. alveolar nn
PM and half the 1st molar: middle sup. alveolar
2nd half M1 and M2 and 3: post. sup. alveolar
NOT EXACT VARIATION MAY OCCUR
Inn of the maxillary gingiva
CNV2 BRANCHES
incisors to canine: half ant sup alveolar and half infra orbital to the distal
PM: mesial=infraorbital, distal=mid sup alveolar
M: post sup alveolar
man teeth inn
CNV3 BRANCHES
anterior teeth: incisive branch of the inf alveolar
posterior: dental branches of the inf. alveolar
man gingival inn
CNV3 BRANCHES
anterior+PM: mental branch of the inf alveolar
M: buccal branch
inf alveolar continues on past the teeth as?
mental branch of CNV3
where does the inf alveolar nn enter the mandible, landmark?
mandibular foramen, lingula
additional motor inn of CNV3
mylohyoid
ant belly digastric
tensor veli palatini
tensor typmpani
descidous teeth eruption pattern
CI>LI>C>M1>M2
permanent teeth eruption pattern
M1>CI>LI>C>PM1>PM2>M2>M3
opening/closing of the eutachian tube
opens and close with the salpingopharyngeal fold, action done by the tensor palatini veli inn by CN V3
portions of the palate/composition
Hard: maxilla and palatine bones
soft: mm/aponeurosis, mucosa, palatine glands
portions of the pharynx sup to inf
nasopharynx
oropharynx
laryngopahrynx
what can be found in the nasopharynx
eustachian tube
isthmus of the pharynx/transition to oropharynx
contents of the oropharynx
palatopharyngeal arch
palatoglossal arch
from the palate to the tongue
contains palatoglossus mm
