Lecture 40: Ruminant Head digestive/respiratory Flashcards
List the order of structures air travels starting at the nasal cavity
nasal cavity
nasopharynx
intrapharyngeal ostium(epiglottis)
larynx
trachea
List the order of structures food travels starting at the oral cavity
oral cavity
oropharynx
laryngopharynx
esophagus
List the order of structures you’ll pass when placing an ETT
oral cavity
oralpharynx
go above the epiglottis
larynx
trachea
what meatus does a nasogastric tube pass
ventral meatus
How is the ETT tube located in terms of the arytenoids and epiglottis
dorsal to epiglottis
ventral to arytenoids
why are rabbits/horses/ruminants harder to intubate compared to a carnivore
their mouth does not open as wide compared to a carnivore
How does food travel in terms of the epiglottis
Food will pass from oral cavity–> oropharynx–> DORSAL to the epiglottis to reach the laryngopharynx and into the esophagus
label 1 and 2
- esophagus
- trachea
List the meatuses and nasal conchas in the bull skull
common meatus
dorsal meatus
middle meatus
ventral meatus
ventral concha
dorsal concha
middle concha
ethmoid concha
is the vomer bone bilaterally symmetrical
NO, only bone of skull that is “singular”
what is this picture showing
Food ingesta route from oral cavity to esophagus
what is this showing
Route of air inspired from nose to trachea
Identify E,F,G
identify A,B,C,D

what is important about the dorsal cricoarytenoid m.
abducts/open the glottis
if damaged, hemiplasia can occur

what is this structure
Hyoid apparatus

How does the lingual process differ in a bovine compared to equine species
lingual process of basihyoid bone is much less
prominent when compared to the Equine spp.
