functions of nasal cavity

Answer 4

Warms and humidifies inspired air

Removes and traps pathogens from inspired air

Sense of smell

Answer 6

cartilage

Question 10

meatus function

Answer 10

gap to allow air to travel when you inhale exhale

Question 11

concha function

Answer 11

swirl up air as it passes through cavity so more time to trap pathogens and warm air and add SA to nasal cavity

Question 12

what happens in a cold

Answer 12

meatus becomes smaller blocked nose sensation

Question 13

Answer 13

4
Frontal sinuses
ethmoid sinuses
sphenoid sinuses
maxillary sinuses

Question 14

function of sinus

Answer 14

Answer 17

Roof – hard palate (maxilla + palatine) anteriorly, muscular soft palate posteriorly

Floor – muscular with scaffolding from mandible

Question 20

3 parts in pharynx

Answer 20

nasopharynx (pharyngeal tonsil, opening of pharyngotympanic tube, uvula)

layngopharynx (everything below superior epiglottis and above circoid cartilage)

Question 21

what kinds of muscles make up pharynx

Answer 21

circular

longitudinal

Eustachian tube connects

Answer 22

middle ear to nasopharynx

Question 23

role of Eustachian tube

Answer 23

drain middle ear
produces mucous
equalise pressure entre middle ear and nasopharynx

Question 24

what happens if Eustachian tube is blocked as a result of upper respiratory tract infection

Answer 24

accumulation of fluid in middle ear –> ear blocked feeling

how many cartilages make up the larynx

Answer 29

9
Three unpaired – Epiglottis, Thyroid and Cricoid
Three paired – Arytenoid, Corniculate and Cuneiform (Anterior to Corniculate)

Question 30

where are vocal cords located

Answer 30

larynx

Question 31

role of epiglottis

Answer 31

flops down to protect lower airway

Question 32

specificity of circoid cartilage

Answer 32

only cartilage to form complete ring around airway

Question 33

on what cartilage do vocal cords attach

Answer 33

arytenoid cartilage

Question 34

which larynx muscle produce sound

Answer 34

intrinsic muscles of larynx

Question 35

which larynx muscle changes pitch of sound

Answer 35

circothyroid muscle

Question 36

what two nerves supply neuronal innervation of larynx

Answer 36

superior laryngeal and recurrent laryngeal, two branches of vagus

Question 37

what parts of larynx does recurrent laryngeal innervate

Answer 37

motor to ALL intrinsic muscles except circothyroid

sensory to area below vocal cords

responsible for phonation

Question 38

what parts of larynx does superior laryngeal innervate

Answer 38

internal laryngeal:
sensory to area above vocal cords

external laryngeal:
motor to circothyroid muscle
responsible for PITCH

Question 39

which nerve innervates circothyroid muscle

Answer 39

external branch of superior laryngeal

Question 40

result from damage to recurrent laryngeal

Answer 40

caused by lung tumour for example…

you get vocal cord paralysis on affected side –> horse voice and dysphonia
stridor if both sides are affected

Question 41

result from damage to exterior laryngeal

Answer 41

due to thryoidectomy

paralysis leads to low pitch voice and reduced range

Question 42

which artery supplies most of exterior head and neck

Answer 42

external carotid artery

Question 43

which arteries branch from the external carotid artery

Answer 43

Superior thyroid artery
Ascending pharyngeal artery
Lingual artery
Facial artery (lower face)
Occipital artery
Posterior auricular artery
Maxillary artery
Superficial temporal artery

septal branch of sphenopalatine
terminal part of greater palatine artery
septal branch from nasal artery from superior labial artery
