25
Q

Middle ear parts

A

26
Q

Inner ear parts

A

Otic capsule (semicircular canals, cochlea, CN VIII)

27
Q

What are the minute structures of the glottis?

A

Anterior and posterior glottis, macula flava, and vocal processes.

28
Q

Which minute structure of the glottis is the intermembranous portion and is where the most ripple takes place?

A

Anterior glottis

29
Q

Which minute structure of the glottis has the biggest opening for respiration and is the intercartilagenous portion?

A

Posterior glottis

30
Q

Which minute structure of the glottis is attached to thyroid cartilage and attaches the anterior glottis to the thyroid bone by anterior tendon?

A

Macula flava

31
Q

Which minute structure of the glottis aren’t very vascular and bend at the elastic cartilage with abduction and adduction?

A

Vocal processes

32
Q

3 sections of the layered vocal folds

A

Cover, transition, and body.

33
Q

What elements are in the cover of the layered vocal folds?

A

Epithelium, nasal lamina, superficial layer of lamina propria

34
Q

What element is in the transition of the layered vocal folds?

A

Intermediate and deep layers of lamina propria

35
Q

What element is in the body of the layered vocal folds?

A

Thyroarytenoid

36
Q

What is epithelium?

A

The vibratory portion of the vocal folds. Sheds to maintain its health.

Anterior: stratified squamous epithelium
Posterior: pseudostratified ciliated epithelium

37
Q

What is considered the basement membrane zone?

A

Basal lamina

38
Q

The basal lamina has 2 parts…

A

Lamina Lucida-low cellular density right next to epithelial cells

Lamina Densa-more dense right next to lamina propria

39
Q

Viscoelasticity

A

Mucosal wave where tissue rolls like water and is determinate of vibratory behavior.

40
Q

What is the basal lamina?

A

Physical support to the epithelium and is primarily where injury takes place

41
Q

What are extra cellular matrices?

A

Fibers of the vocal folds that are between cells for support. No innervation.

Reticular, collagenous, and elastic.

42
Q

Where is the larynx birth until age 5?

A

Up high almost part of the skull when it drops down to C5

43
Q

At birth where is the epiglottis?

A

The Dorsum of the tongue making it difficult to breathe through the mouth.

44
Q

At birth where is the hyoid bone and thyroid cartilage?

A

On top of each other

45
Q

At birth where is the narrowest part of the airway?

A

Subglottic region

46
Q

At birth, what does the lamina propria have?

A

1 layer with no vocal ligament

47
Q

When does the 3rd layer of lamina propria begin to form?

A

Adolescence

48
Q

When does the larynx descend into its permanent position?

A

Adolescence

49
Q

What are mens and women sex hormones?

A

Men: testosterone and androgen

Women: estrogen and progesterone

50
Q

What happens to cartilages in adulthood and old age?

A

Adulthood: ossify and calcify

Old age: continues to calcify and sometimes turns to bone

51
Q

In old age, what happens to the superficial layer of lamina propria?

A

It thins

52
Q

What is presby larynges?

A

Aging of the vocal folds where they develop a bow shape and can’t fully close

53
Q

In old age, what happens to women’s vocal folds and men’s vocal folds?

A

Women’s: reinkes space thins and vocal folds become thicker

Mens: pitch rises
