Flashcards in Clinical Relevance Of The Larynx 2 Deck (47):
1

What are the two types of pretracheal fascia

Visceral or muscular

2

Where si the larynx found.

Anterior to laryngopharynx
Between carotid sheaths
Between c4-c6

3

What sit he larynx an important factor in

Upper RESP tract

4

What does the larynx communicate with

Oro and naso pharynx above
Becomes trachea below at c6 cricoid cart

5

How does the larynx help the URT

Keeps it open/patent

6

What si the larynx made of

Rigid Skelton of cartilage and little bone

7

What are the other functions of the larynx

Help prevent entry of foreign bodies - vocal cords and cough reflex

Produce sound - vocal cords

8

What does the full Skelton of the larynx consist of

Epiglottis Hyoid bone
Thyrohyoid mem
Thyroid cartilage
Crop thyroid mem
Cricoid cart
Trachea

9

What is the only complete ring of cartilage

Cricoid

10

What si the Cricothyroid mem imp For

Access for puncture

11

Why is the epiglottis different

Made of elastic cartilage rather than hyaline

12

What does the trachea consist of

C ring of cartilage but smooth muscle trachealis maintain patency

13

What are the parts of the thyroid mem

SUPEIROR horn of the thyroid Cart
Laryngeal prominence
Inferior horn of thyroid cart

14

What does the cricoid cartilage consist of

Arch
Lamina

15

What kind of joint is the Cricothyroid joint

Synovial

16

What does the Cricothyroid joint allow

A-P movement of the head allowing nodding

17

What a re the processes of the arytenoid cartilages

Corniculate
Muscular
Vocal

18

What are the vocal cords

Thickened ligaments between thyroid cart and vocal processes of arytenoid carts

19

Where are the cuneiform and corniculate ligaments located

Deep to laryngeal muscle

20

What do the corniculate and cuneiform cartilages do

Support laryngeal inlet not part in moving vocal cords

21

What si the rims glottidus

Space between vocal cords where air passes

22

What si the vocal cord

Vocal ligament covered in mucosa vocal fold

23

How many carts

9

24

What are the pairs of cart

3 pairs

Corniculate
Cuneiform
Arytenoids

25

What a re the single carts

3

Epiglottis
Thyroid
Cricoid

26

What is an endotracheal intubation

Placing a breathing tube inside the trachea

27

What si the endotracheal tube inserted through

Mouth or nasal cav

Oropharynx

Laryngeal inlet

Rima glottidus

Trachea

28

What si the endotracheal tube not inserted into

Main bronchi as May inflate only one lung and the other will collapse

29

What is a laryngoscopy

Viewing inside the larynx with a laryngoscope

30

How do u carry out a largngoscopy

Blade inserted in valeculla,a between tongue and epiglottis

31

What kind of mucosa is in the larynx

Respiratory epithelium

32

What kind of epithelia are the vocal cords

Stratified squamous epi

33

Since the epi of the larynx is RESP what does this mean

Sec mucous
Cilia waft to pharynx
Mucociliary escalator

34

What divides the laryngeal mucosa

Vocal cords

35

What are false vocal cords called

Vestibular folds

36

Where are the false vocal cords and what do they do

Superior to true
Thickened folds to protect airway

37

What are the true vocal cords called when covered in mucosa

Vocal fold

38

What nerve innervates the laryngeal mucosa

Vagus

39

What parts of the vagus innervate what part of the larynx

Superior to vocal fold - internal laryngeal branches of superior laryngeal branch of vagus

Inferior I to vocal fold and vocal fold - recurrent laryngeal branches of vagus

40

What does the recurrent laryngeal nerve loop

Under and back up at aorta arch

41

What are some details about the intrinsic muscles of the larynx

All skeletal muscle
All voluntary
Move vocal cords - tensors, extensirs, adductors, abductors
All supplied with motor branches of vagus

42

What do the crucothyroid mucles do

Tense vocal cords
Nodding at joints

43

What are the thyroartyeinid carts

Relax vocal cords
Pull arytenoids to thyroid

44

What do the lateral crico arytenoid carts do

Adduct vocal cords
Rotate arytenoid cart So that the vocal processes if carts come together midline

45

What do the arytenoid muscles do

Traverse and oblique
Assist lat crico to gently close rima glottidus
Sphincter function
Crico thyroid also contracts

46

What does the post crico arytenoid do

Adduct vocal cords
Rotate arytenoid carts so vocal processes carts move
Winded rima glottidus

47

What does the pretracheal fascia enclose

Strap muscles
Thyroid gland
Trachea
Larynx
Oes
