Speech Anatomy

Question 1

What are the systems of speech

Answer 1

Respiratory, Phonatory, Resonatory, Articulatory, Nervous system, and auditory system

Question 2

Define Respiratory

Answer 2

(lungs) provides the energy source for speech

Question 3

Define Phonatory

Answer 3

(larynx) provides the voicing (all vowels and certain phoneme)

Question 4

Define resonatory

Answer 4

acoustic source provided by voicing is modified within the pharyngeal, oral and nasal cavities

Question 5

define articulatory

Answer 5

acoustic source provided by voicing are modified by oral motor structures (mobile and immobile)

Question 6

define nervous system

Answer 6

(cns and pns) controls musculature, receives and makes sense of input information

Question 7

define auditory system

Answer 7

processes speech and non speech acoustic signals received and perceived by listener

Question 8

what are the text system of speech

Answer 8

respiratory, laryngeal, and supralaryngeal

Question 9

what are the mobile articulators

Answer 9

tongue, lips, velum, soft palate and jaw

Question 10

what are the immobile artiuclators

Answer 10

alveolar ridge, teeth and hard palate

Question 11

what are the anatomical structures of the larynx

Answer 11

Epiglottis, Hyoid bone, thryrohyoid membrane, throid cartilage, laryngeal prominences, criticoid cartilage, tracheal cartilage, cricothyroid ligament, trachea

Question 11

What are the 3 major sections of the pharynx

Answer 11

Laryngopharynx
oropharynx
nasopharynx

Question 12

what are the supralaryngeal system and articulators?

Answer 12

alveolar ridge, lips, teeth, madible, oral cavity, tongue, velum, hard palate and nasal cavity

Question 13

What does the parynx do?

Answer 13

It directs airflow from larynx to oral and nasal cavities

Question 14

Name the basic anatomy of the Larnynx

Answer 14

thyroid cartilage, arytenoid cartilages (2), corniculate cartilages, cricoid cartilages, epiglottis (directs food into the esophagus), hyoid bone, and glottis (space between the vf’s)

Question 15

what is the difference between adduction and abuduction?

Answer 15

Adduction the vocal folds come together - they close

Abduction the vocal folds seperate - they open

Question 16

What is the Bernoulli effect?

Answer 16

It is the drop in air pressure created by increased airlfow through a constriction that causes intense vocal fold adduction.

Question 17

What are the function of inhalation?

Answer 17

• Thoracic cavity expands to allow lungs room to expand
• diaphragm contracts and lowers which expands thoracic cavity
• external intercostal muscles working during inhalation
• pressure differences are what trigger the process of inhalation-exhalation

Question 18

Describe the functions of exhalation

Answer 18

• Lungs deflate - thoracic cavity space decreases
• Diaphragm relaxes and rises
• Internal intercostal muscles at work during exhalation
• air moves from the lungs into the trachea and up to the level of the larynx which causes the vocal folds to vibrate.
