1
Q

This is the alimentary layer of the neck viscera

A

Pharynx

2
Q

What are the 3 components of the nasopharynx

A
  • Choanae
  • Pharyngeal tonsils
  • Pharyngotympanic tube
3
Q

This is the posterior border of the nasal conchae and you have to go through this to get to the nasal pharynx

A

Choanae

4
Q

This connects the middle ear to the nasal pharynx

A

Pharyngotympanic tube

5
Q

What is the purpose of the pharyngotympanic tube?

A
  • Get atmospheric air to middle ear

- Middle ear ventilation

6
Q

What is located in the oropharynx

A

The palatine tonsils

7
Q

This is partly shared with the alimentary tract

A

The laryngopharynx

8
Q

What are the 2 components in the laryngopharynx?

A
  • Piriform fossa

- Esophagus

9
Q

Describe the piriform fossas/recess

A

it is between the pharynx and the outer surface of the epiglottis
-where your food goes when you swallow

10
Q

This is the outer edge of the epiglottis?

A

Aryepiglottic fold

11
Q

Where does the pharynx begin?

A

-Basilar part of the occipital bone

12
Q

Where does the pharynx end?

A

-Inferior border of cricoid cartilage

13
Q

In your pharynx, where are your circular and longitudinal muscles?

A
  • Circular= internal

- Long=external

14
Q

What are the pharyngeal constrictor muscles

A
  • superior
  • middle
  • inferior
15
Q

What innervates the pharyngeal constrictor muscles?

A

-Vagus nerve

16
Q

Describe the fibers in the autonomic nerve

A

-Autonomic nerve with parasympathetic and sympathetic fibers

17
Q

What are the longitudinal pharyngeal muscles?

A
  • Stylopharyngeus
  • Salpingopharyngeus
  • Palatopharyngeus
18
Q

What innervates the stylopharyngeus

A

Glossopharyngeal

19
Q

What innervates salpingopharyngeus and palatopharyngeus?

A

Vagus nerve

20
Q

What are the unpaired cartilages of the larynx

A
  • Epiglottis
  • Thyroid
  • Cricoid
21
Q

What are the paired cartilages of the larynx

A
  • Arytenoid
  • Corniculate
  • Cuneiform
22
Q

This protects the opening of the trachea and it is made of elastic cartillage

A

Epiglottis

23
Q

This ligament is the first projection off of the cricoid cartilage

A

-Arytenoid cartilage

24
Q

This cartilage arises from the arytenoid cartilage

A

Corniculate cartilage

25
Q

This cartilage holds the mucosa on the walls lateral to the epiglottis

A

Cuneiform cartilage

26
Q
  • This prohibits the epiglottis from sagging and blocking the airway
  • inlet to the larynx
  • Folds run in an oblique plane
A

Aryepiglottic fold

27
Q

This is the opening of the laryngopharynx to the larynx

A

Aditus

28
Q

Describe the vestibular folds

A

-Fake vocal cords and they are used for protection

29
Q

What is the space between the vestibular folds and the vocal folds

A

ventricle

30
Q

These 2 structures make up the true vocal folds

A
  • Vocal ligament

- Vocalis muscle

31
Q

The conus elasticus is made up of these 2 components

A
  • vocal ligament

- lateral cricothryoid ligament

32
Q

What covers the vocal folds?

A

Mucosa

33
Q

What is the opening of the glottis called?

A

Rema

34
Q

When does the rema glottis exist?

A

When the true vocal folds are open

35
Q

What plane are the glottis structures in?

A

Horizontal plane

36
Q

T/F- The larynx is osteomembranous

A

True

37
Q

What is the purpose of the laryngeal muscles?

A
  • Voluntary

- Frequency and intensity of voice are controlled here

38
Q

What are the 6 laryngeal muscles?

A
  • Cricothyroid
  • Cricoarytenoid
  • Transverse arytenoid
  • Oblique Arytenoid
  • Thyroarytenoid
  • Vocalis
39
Q

These muscles abduct and open the rema

A
  • Cricothryoid

- Cricoarytenoid

40
Q

These muscles adduct the vocal folds and close the rema

A
  • Transverse arytenoid
  • Oblique Arytenoid
  • Thyroarytenoid
  • Vocalis
41
Q

What innervates the laryngeal muscles

A

The recurrent laryngeal branch of the vagus nerve

42
Q

Describe the movement of the cricoarytenoids and the 2 types

A
  • lateral and posterior

- glide, swivel, and tilt

43
Q

What are the pre-vertebral muscles of the neck? The deep ones

A
