The Rhinarium Flashcards
What forms the boundary of the nasal cavity
Dorsally nasal/frontal bone, ventrally the hard/boney palate (maxilla, incisive, palatine bones), caudally the cribiform plate of the ethmoid
what is the opening from the nasal cavity into the pharynx
choanal region
what are the components of the nasal septum
cartilaginous (vomer, nasal/frontal, ethmoid) and bony (ethmoid)
are the ventral or dorsal conchae greater
ventral (especially in dogs)
what are the spaces created by conchae
meatus (meatuses)
what are the three parts of the ethmoid bone
transverse plate (cribiform plate), vertical plate (bony nasal septum), ethmoidal conchae
what passes through the cribiform plate
nerve endings of CN I (olfactory nerve)
what does the nasolacrimal duct travel through
maxilla
what sinus is pig-specific
lacrimal sinus
which nerve rests upon a bony pedicle
infraorbital n
