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
B - Middle nasal meatus
C - Alar fold
D - Ventral nasal meatus
E - Vomer bone
ID these structures (sectioned at canines)
A - Dorsal nasal meatus
B - Middle nasal meatus
C - Common nasal meatus
D - Ventral nasal meatus
E - Palatine process of maxilla
ID these structures:
A - Opening of nasolacrimal duct
B - Nasolacrimal duct
C - Ventral punctum
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.
What are the regions of the pharynx?
Oropharynx
Nasopharynx
Laryngopharynx
ID these pharyngeal structures or spaces
A - Hard Palate
B - Soft Palate
C - Nasopharynx
D - Intrapharyngeal ostium
What are the boundaries of the oropharynx?
Cranial - palatoglossal fold/arch
Caudal - base of epiglottis
Dorsal - soft palate
Ventral - root of tongue
What envelops the palatine tonsil?
Tonsillar fossa and tonsillar fold
What are the boundaries of the nasopharynx?
Cranial - choanae
Caudal - intrapharyngeal ostium
What are the boundaries of the laryngopharynx?
Cranial - palatopharyngeal arches
Caudal - pharyngoesophageal limen
ID these structures of the pharynx
A - Pharyngoesophageal limen
B - Epiglottis
C - Soft Palate
D - Intrapharyngeal Ostium
E - Choana
