What is spinal cord injury
Acuired impairment of speech due to paralysis of the muscles of inspiration
What kind of hearing impairment is deafness and what does it affect
Congenital and affects articulation development
What is laryngectomy
Aquired impairment of voice
What is Dysarthria
Aquired impairment of articulation due to a brain stem tumor
What is aphasia
Aquired impairment of language due to left hemishere brain damage after stroke
What are the 3 major domains of communication disorders
Speech, Language and Hearing
What does speech production require
Respiration, phonation, and articulation
What is the primary function of the lungs
air exchange
On what is speech produced
Exhalation
Can you speak on inhalation
Yes, but its not efficient
What is the primary muscle of inspiration
The diaphragm, also rib cage assists
Inspiration (breathing in)requires what
muscle contraction
What are intercostal muscles
Muscles that connect the ribs
What is the spirometer used for
To record the movement of air during respiration
What is the vital capacity of a man/woman
male: 5 L
females: 4 L
If there is a paralysis of the muscles of respiration then it requires what
a respirator to pump the lungs with air
For the respirator, if air pressure provides the power source for speech, what provides the sound
The larynx
What is the primary function of the larynx
To prevent aspiration
watchdog for the trachea
guards against inhalation of food or liquid into airway
What creates voicing
The vibrating vocal folds release puffs of air
What determines the pitch of the voice
The rate (frequency) of vocal fold vibration
What causes changes in pitch
Pull on the vocal folds
increase the tension
faster vibration = higher pitch
What causes changes in loudness
Increase the force of the air pressure
Where does the respiration for speech occur
In the mid range of your vital capacity
How doe voice become speech
* The lungs provide the air pressure/flow
*The larynx provides the voice
Why is the movement of the ariculators necessary
To produce different speech sounds
What does articulate mean
To bring together
How do the lips change the sound
*Rounding
*Spreading
*Stopping airflow
How does movement of the jaw affect sound production
* Raise and lowers
* tongue moves with jaw
What is another word for the soft palate
Velum
What does the velum do for all oral sounds (non-nasal consonants and vowels)
Velum raises for oral sounds
What does the velum do for nasal sounds: m/ng/n
Velum lowers for nasal sounds
Where are sounds waves modidified
By the oral and nasal cavity
What is hypernasality and hyponasality
*too much nasality
*lacking normal nasal resonance
Speech sounds involves neural messages from the brain to where
*brain stem and cranial nerves (face & neck)
*spinal cord & spinal nerves (chest wall & hands)
What does neurogenic mean
Neurologic cause
What is the trigemenal V cranial nerve for
Jaw movement
What is the facial VII cranial nerve for
Face
What is the glasopharyngeal IX cranial nerve for
Tongue/Pharynx
What is the hyphoglossal XII cranial nerve for
