What are the cranial and caudal boundaries of the nasal cavity?
What divides the nasal cavity sagitally? |
Cranial - nostrils (nares)
Caudal - choanae (internal nares) Nasal septum divides the nasal cavity sagitally. |
|
What are the cranial and caudal boundaries of the choanae?
|
Cranial - nasal cavity
Caudal - nasopharynx |
|
What is the bare skin around the nostrils called?
|
Nasal plenum
|
|
ID these regions of the nasal vestibule:
|
A - Dorsal nasal concha
B - Ventral nasal concha C - Alar fold D - Nasaolacrimal duct |
|
What forms the external nose?
|
Bone and cartilage
(Incisive, maxilla, and nasal bones) Hyaline cartilage |
|
What are the regions of the nasal septum? Where are they located in relation to one another
|
Osseous, Cartilaginous, and Membranous
Bony is caudal and membranous is rostral |
|
T or F:
Both the dorsal and ventral nasal conchae are attached to the maxilla. |
False, yo! Only the ventral is. The dorsal attaches to the ethmoid and nasal bones!
|
|
ID these structures and passages
|
A - Dorsal nasal meatus

|
What are the three major cranial sinuses in dogs and cats? Which sinus is the largest?
|
Frontal (largest)
Maxillary Sphenoid |
|
T or F:
Persian cats have a reduced or absent frontal sinus |
True! Stupid flat faced kitty
|
|
What structure is found within the maxillary recess?
|
Lateral nasal gland
|
|
T or F:
In both dogs and cats, the sphenoid sinus is only a potential cavity since it is entirely filled by an endoturbinate scroll. |
False. This is true only in dogs.
