Exam 1 Part 15

Question 1

When formant frequencies and fundamental frequency matches

Answer 1

Vocal tract tuning

Question 2

Type of tumor that invades deeper layers of the vocal folds causing dysphonia

Answer 2

Laryngeal carcinoma

Question 3

Dysphonia severity depends on what 2 factors?

Answer 3

Location, extent of tumor invasion

Question 4

What are risk factors of laryngeal carcinoma?

Answer 4

Smoking, alcohol use, laryngopharyngeal reflux (LPR)

Question 5

What types of treatment do we use for laryngeal carcinoma?

Answer 5

Radiation therapy, chemotherapy, surgery

Question 6

________ is the driving source, and _______ is

the sound source for voice production.

Answer 6

Positive subglottal pressure, changing glottal airflow

Question 7

T/F: During the bicep curl, we notice a stretch in triceps. The former is a
passive and latter is an active contraction of muscles.

Answer 7

False

Question 8

T/F: When CT muscle contracts, the vocal folds become longer and thinner. There will be an increase in passive tension of the muscles. This phenomenon helps to
raise the pitch.

Answer 8

True

Question 9

Why are extrinsic laryngeal muscles important?

Answer 9

Important for swallowing, phonating, changes the shape of the vocal tract and resonance

Question 10

What is the difference between suprahyoids and infrahyoids in terms of laryngeal function?

Answer 10

Suprahyoid raises the larynx by pulling the hyoid up, infra hyoids lower the the larynx by pulling the hyoid/larynx to a lower position in the neck

Question 11

The motor innervation of intrinsic laryngeal muscles is done by ______________ laryngeal nerve except CT muscle which is innervated by _______________ laryngeal nerve.

Answer 11

Recurrent, external branch

Question 12

T/F: Superior and inferior laryngeal arteries are the branches of external carotid artery

Answer 12

True

Question 13

First thing to do to initiate vocal fold vibration:

Answer 13

Glottal adduction

Question 14

The ratio of membranous (M) to cartilaginous (C) vocal folds in infants:

Answer 14

M=C

Question 15

During vocal fold vibration, at point of maximum displacement, ______ (inertial or elastic restoring) forces are maximum.

Answer 15

Elastic

Question 16

When the length of a body increases, what happens to the fundamental frequency (assuming tension and mass are constant)

Answer 16

Decreases

Question 17

When the tension of a body increases, what happens to the fundamental frequency (assuming length and mass are constant)?

Answer 17

Increases

Question 18

When the mass of the body increases, what happens to the fundamental frequency (assuming that length and tension are constant)?

Answer 18

Decreases
