Anatomy & Physiology of Speech
The structure that houses the vocal folds and produces voice.
What is the larynx?
The three small bones located in the middle ear.
What are the malleus, incus, and stapes?
The system is responsible for supplying the airflow needed for speech production.
What is the respiratory system?
A motor speech disorder caused by muscle weakness.
What is dysarthria?
The medical term for swallowing.
What is deglutition?
The cartilage that forms the “Adam’s apple.”
What is the thyroid cartilage?
The spiral-shaped structure is responsible for converting sound vibrations into neural signals.
What is the cochlea?
The perceptual quality of sound related to how high or low a voice sounds.
What is pitch?
A neurological condition affecting language processing due to brain damage.
What is aphasia?
The space between the vocal folds.
What is the glottis?
The only intrinsic laryngeal muscle that abducts the vocal folds.
What is the posterior cricoarytenoid muscle?
The cranial nerve responsible for hearing and balance.
What is the vestibulocochlear nerve (CN VIII)?
The scientific measure of how fast vocal folds vibrate, measured in Hertz.
What is fundamental frequency?
A speech disorder involving impaired motor planning for speech movements.
What is apraxia of speech?
The swallowing evaluation that uses a flexible endoscope inserted through the nose to view the pharynx during swallowing.
What is Fiberoptic Endoscopic Evaluation of Swallowing (FEES)?
The broad posterior plate of the cricoid cartilage.
What is the lamina?
The type of hearing loss is caused by damage to the inner ear or auditory nerve.
What is sensorineural hearing loss?
The aerodynamic measurement represents air pressure below the vocal folds.
What is subglottal pressure?
The type of aphasia characterized by nonfluent speech and damage to the left frontal lobe.
What is Broca’s aphasia?
The communication disorder that affects the rhythm, rate, and flow of speech.
What is fluency disorder (stuttering)?
The theory explaining vocal fold vibration involves tissue elasticity, muscle tension, and airflow.
What is the Myoelastic-Aerodynamic Theory?
A diagnostic test used to evaluate outer hair cell function in the cochlea.
What are otoacoustic emissions (OAEs)?
The acoustic measure representing how much sound energy is present in a speech signal, typically measured in decibels.
What is intensity?
The brain region in the temporal lobe is primarily responsible for language comprehension.
What is Wernicke’s area?
The professional organization in the United States that sets standards and certification requirements for speech-language pathologists and audiologists.
What is the American Speech-Language-Hearing Association (ASHA)?
