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
  • Longus colli
  • longus capitus
  • rectus capitus anterior
  • rectus capitus lateralis
  • scalenes (ant, mid, post)
