Dr. Concha
What is the difference in nostrils between small and large ruminants?
large: comma shape, rigid and less movable
small: slit-like shape
Where do rings on a ruminant go through?
the most rostral portion of the nasal septum
What is this?
where rings go through the nasal septum (most rostral part)
What is this?
bull nose plier - bull nose lead - bull holder
Ruminants have a more prominent [dorsal/middle/ventral/ethmoid] conchae
middle
Label 1-5
- conchae
- ventral conchae
- dorsal conchae
- middle conchae
- ethmoid: ethmoturbinates

Where does the nasal septum extend?
caudally into the nasopharynx
What is the pharyngeal septum? What does it contain?
septum of mucosa that incompletely divide the dorsal area of the nasopharynx
contains the pharyngeal and tubal tonsils
What is an extension of the nasal septum?
pharyngeal septum
What is choana?
communicate with nasal cavity and nasopharynx
