Oral + Nasal Cavities Flashcards
compound origin of nasal/oral cavity
olfactory capsule (ethmiod - chondrocranium), upper jaw (splanchnocranium)
chondrocranium is supplied by blank
internal carotid
splanchnocranium is supplied by blank
external carotid
at the blank we lose voluntary control of swallowing which causes the gag reflex
palatoglossal fold (stomodeum)
jaws are supplied by these nerves
V2, V3
tongue develops from blank and migrates into oral cavity dragging its motor supply with it which is blank
cervical myotomes, CN XII
tongue gets general sense from these
V, IX
tongue gets taste from these
VII, IX, X
this fuses with medial nasal prominences to form upper lip
maxillary prominences
these fuse to form the lower lip and jaw
mandibular prominences
furow between maxillary and lateral nasal prominences that forms nasolacrimal duct and lacrimal sac
nasolacrimal groove
fusion of medial nasal prominences to form the philtrum of the lip and blank
primary palate
failure of palate to fuse
cleft lip/palate
these fuse with primary palate at incisive foramina and nasal septum
secondary palate
attachment of falx cerebri
crista gallae
gateway to and from nasal cavity for vessels and nerves
sphenopalatine foramen
aka nostril
vestibule
vestibule leads to blank
atrium
atrium leads to blank
nasal cavity
open back walls of nasal cavity at junction with nasopharynx
choanae
sinuses develop with blank
age
curved slit with rounded superior edge, has openings into ethmoid air cells, infundibulum, ostium for max sinus
hiatus semilunaris
hiatus semilunaris is located in the blank
middle meatus
