Flashcards in Upper Respiratory Tract Deck (44):
1

Upper respiratory tract includes

Pharynx
Oesophagus
Larynx
Oral Cavity
Nasal Cavity

2

What are the main bones

Ethmoid
Maxilla
Palatine bone
Mandible
Hyoid Bone

3

What is the purpose of the mucous membrane in the nasal cavity

Highly vascular --> warms air up, traps foreign particles and humidifies air

4

Where are the three turbinates found

Lateral wall of nasal cavity

5

What are the three turbinates

Superior concha
Middle concha
Inferior concha

6

Which two turbinates form part of the ethmoid bone

Superior and middle

Inferior has a separate bone

7

What is the role of chonca

they are lined with mucosa and produce turbulance which makes the air stay in longer --> therefore warmer

8

What is a meatus

Passage below each concha --> air flows through

9

What are the four paranasal sinuses

Frontal, ethmoid, sphenoid and maxilarry

10

Which paranasal sinus is susceptible to injury

Ethmoid --> small and thin

11

Which paranasal sinus is susceptible to infection

Maxillary --> below the nasal cavity therefore easy to get in

12

When do the paranasal sinuses develop>

Only once teeth appear

13

What do the paranasal sinuses act to do?

Lighten skull
Lined with mucosa
V. vascular

14

The oral cavity comprises

Lips
Mandible
Mylohyoid muscle
Tongue
Soft Palate
Hard Palate
Uvula

15

What sort of muscle is the tongue

Skeletal

16

What is the tongue covered in

Epithelium

17

What two types of skeletal muscle comprise the tongue

Intrinsic and extrinsic

18

What role does intrinsic tongue muscle do?

Alters the shape --> has attachments WITHIN the tongue

19

What role does extrinsic tongue muscle do?

Alters the position of the tongue --> attachments OUTSIDE of the tongue

20

How many teeth does an adult have

32

21

What are the different types of teeth?

Incisors
Canine
Premolar
Molar

22

What type of tooth is a wisdom tooth

Molar

23

What is the role of molar teeth

Grind

24

What is the role of canine teeth

Anchor

25

What is the role of incisors

Cutting

26

What is the anatomical name for voice box

Larynx

27

What protects the larynx anteriorly?

Laryngeal cartilage

28

To create phonation the vocal ligs have to

Adduct

29

To breath our vocal ligs have to

Abduct

30

Phonation and breathing occur due to the vocal ligaments being altered by what muscles?

Intrinsic muscles of larynx

31

What structures protect the larynx

Vestibular folds
Vocal Folds

32

Describe the pharynx

Muscular Tube
Lies in front of cervical vertibrae

33

Nasopharynx is found

Directly below base of skull

34

Pharyngotymphanic tube connects which two structurs?

Middle ear and nasopharynx

35

What is the nasopharynx lined with

Mucuous membrane

36

What type of muscles make up the external layer of pharynx?

Constrictors

37

What are the three type of constrictor muscles of the pharynx

Superior
Middle
Inferior

38

Where is the laryngopharynx located

Beneath larynx
Upper most part of trachea

39

40

What structures does the oropharynx include

1/3 of posterior tongue
