Nasal Cavity Flashcards
What a re the three regions of the nasal cav
Vestibule
Respiratory
Olfactory
What’s lines the respiratory region
Ciliated pseudo stratified epi with goblet cells
What are the conchae of the nasal cav
Shelves of bone which act as turbinates and increase the sa
Inferior
Middle
Superior
What bones form the conchae
Ethmoid - superior and Middle
Independant - inferior
What are the four meatuses
Inferior
Middle
Superior
Sphenoethmoidal recess
What doe the meatuses drain
Paranasal sinuses
What drains into the Middle meatus
Frontal
Maxillary
Anterior ethmoidal sinuses
What drains Into the superior meatus
Posterior ethmoidal sinuses
What drinks into the sohenoethmidal recess
Sphenoidal sinus
What drains out of the inferior meatus
The nasolacrimal duct
What does the crubiform plate have to do with he nasal cav
Part fo the ethmoid bone
Roof
Perforations for olfactory nerve to enter and exit
What does the sphenopalatine formane allow
Communication between nasal cav and pterygopalatine fossA
What passes through the sphenopalatine foramen
Sphenopalatine artery
Nasopalatine artery
Superiori nasal nerves
What si the incisive canal
Pathway between nasal cav and incisive fossA of oral cav
What tarvesl through th incisive canal
Nasopalatine nerve and greater palatine artery
What supplies the blood
Ica and Eca
What branches of the Ica contribute to the nose
Anterior and posterior ethmoidal arteries from the Opthalmic artery
What contributes to the nasal cav from the Eca
Sphenopalatine
Greater palatine
Superior labial
Lateral nasal
What does all the arteries supplying the nose do
Anastamosis at littlest area (kiesselbachs) prone to nose bleeds
What does the drainage of the nasal cav go to
Pterygoid venous plexus, facial veins and cavernous sinus
What supplies the special sensory of smell
Olfactory nerve via crubiform plate and has olfactory Mucosa
What supplies the nose with general sensory
V1 - nasociliary
V2 - nasopalatine
What supplies the sensory of the external nose
Trigeminal
What are the functions of the nasal cavity
Warm and humidify air
Remove pathogens
Sense of smell
Drain and clear paranasal sinuses
