24
Q

What do the false vocal folds connect to?

A

Thyroid (front)

Arytenoid (back)

25
Q

What is the space between the false vocal folds called?

A

The false glottis

26
Q

What are the three spaces of the laryngeal cavity?

A

Ventricles
vestibule (supraglottic spaces)
Infra (sub) glottis cavity

27
Q

Where is the Ventricles space on the laryngeal cavity?

A

Between vestibular and vocal folds.

28
Q

What are the two types of laryngeal muscles?

A

intrinsic and Exctrinsic

29
Q

What are the intrinsic muscles?

A
  • Cricothyroid
  • Thyroarytenoid
  • Posterior cricoarytenoid
  • Lateral cricoarytenoid
  • Transverse arytenoids
30
Q

What are the extrinsic muscles?

A
  • Suprahyoid
  • Infrahyoid
  • Omohyoid
  • Sternohyoid
  • Sternothyroid
  • Thyrohyoid
31
Q

Describe the where cricothyroid muscle is

A

Runs from cricoid cartilage to thyroid cartilage.

32
Q

What does the Cricothyroid do?

A

It tightens vocal folds by lifting at front ( pulling back Down)

Higher pitch

33
Q

Where does the Thyroarytenoid & Vocalis run?

A

Passes from THYROID to VOCAL PROCESS (of ARYTENOIDS)

34
Q

What does the Thyroarytenoid & Vocalis do?

A

It relaxes and shortens the vocal folds.

Lowers pitch

35
Q

What is the vocalis?

A

The muscular portion of the Vocal folds

-part of Thyroid-arytenoid muscle that insets into vocal ligaments

36
Q

Where does the Posterior cricoarytenoid run?

A

Back of CRICOID to ARYTENOID

37
Q

What does the Posterior cricoarytenoid do?

A

Rotates arytenoid, separating vocal folds

  • voiceless sounds
  • breathing
38
Q

What are the oblique & transverse arytenoids?

A 
Connects the two arytenoids 
Adduct arytenoids ( closing posterior glottis)
39
Q

Where do the Posterior cricoarytenoid run?

A

CRICOID to ARYTENOID

40
Q

What does the Lateral cricoarytenoid do?

A

Rotates arytenoid. Main adduct, pulls vocal folds together. Closes the glottis

41
Q

What extrinsic muscles Stabilise and support the larynx?

A

-Thyrohyoid
••Sternothyroid
••Inferior constrictor

42
Q

What does the thyrohyoid do?

A

Raise the larynx

-ejectives

43
Q

What does the Sternothyroid do?

A

Pulls thyroid (larynx) downwards

-implosives

44
Q

What does the inferior constrictor do?

A

Stabilises the larynx

45
Q

What are the suprahyoid and their functions

A

-Stylohyoid
••Digastric
••Mylohyoid
••Geniohyoid

  • lift the larynx
46
Q

What are the infrahyoid muscles and their functions?

A

-Omohyoid
-pulls down and back
••Sternohyoid
-pulls down

47
Q

What is the main action of the larynx?

A

Swallowing

48
Q

How does the larynx control swallowing?

A

Palate raised to close nasal cavity ( levator palatini)
.Vocal folds are closed
(Lateral cricoarytenoids)

49
Q

What happens during quiet breathing?

A

Vocal folds are abducted

50
Q

What is forced breathing

A

Vocal folds are abducted plus relaxation

51
Q

What happens vibration?

A

Narrowed glottis:

LATERAL CRICOARYTENOIDS + TRANSVERSE ARYTENOIDS)

52
Q

What is bigger in men?

A

Thyroid

53
Q

What is longer and thicker in men?

A

Vocal folds

54
Q

What are the ventricles known as?

A

Oil can of the vocal folds

55
Q

Where is the vestibule found (supraglottalic space)?

A

From the inlet to venstibularfolds

56
Q

Where is the INFRA (sub)
GLOTTIC CAVITY found?

A

Glottis to trachea

57
Q

What happens with pitch?

A

CRICOTHYROID (stretch), THYROARYTENOID (relax)
