Vestibule
Respiratory
Olfactory

2

What's lines the respiratory region

Ciliated pseudo stratified epi with goblet cells

3

What are the conchae of the nasal cav

Shelves of bone which act as turbinates and increase the sa
Inferior
Middle
Superior

4

What bones form the conchae

Ethmoid - superior and Middle
Independant - inferior

5

What are the four meatuses

Inferior
Middle
Superior
Sphenoethmoidal recess

6

What doe the meatuses drain

7

What drains into the Middle meatus

Frontal
Maxillary

8

What drains Into the superior meatus

Posterior ethmoidal sinuses

9

What drinks into the sohenoethmidal recess

Sphenoidal sinus

10

What drains out of the inferior meatus

The nasolacrimal duct

11

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

12

What does the sphenopalatine formane allow

Communication between nasal cav and pterygopalatine fossA

13

What passes through the sphenopalatine foramen

Sphenopalatine artery
Nasopalatine artery
Superiori nasal nerves

14

What si the incisive canal

Pathway between nasal cav and incisive fossA of oral cav

15

What tarvesl through th incisive canal

Nasopalatine nerve and greater palatine artery

16

What supplies the blood

Ica and Eca

17

What branches of the Ica contribute to the nose

18

What contributes to the nasal cav from the Eca

Sphenopalatine
Greater palatine
Superior labial
Lateral nasal

19

What does all the arteries supplying the nose do

Anastamosis at littlest area (kiesselbachs) prone to nose bleeds

20

What does the drainage of the nasal cav go to

Pterygoid venous plexus, facial veins and cavernous sinus

21

What supplies the special sensory of smell

Olfactory nerve via crubiform plate and has olfactory Mucosa

22

What supplies the nose with general sensory

V2 - nasopalatine

23

What supplies the sensory of the external nose

Trigeminal

24

What are the functions of the nasal cavity

Warm and humidify air
Remove pathogens
Sense of smell
Drain and clear paranasal sinuses
