Introduction Flashcards
Speech and swallowing are referred to as:
brain, muscle, & bone processes
What are the 5 functional systems?
- Nervous system
- Respiratory system
- Phonatory system
- Articulatory system
- Auditory system
- Master Planner
- Develops thoughts into words/sounds, then turns them into muscle movement or motor plans & sends those plans to muscles.
Nervous system
- Power Source
- Provides breath support for speech consisting of exhaled airstream
Respiratory system
- Sound Source
- Using exhaled airstream produces buzz-like sound for AUDIBILITY over distance
Phonatory system
- Sound Shaper
- Rapidly modifies buzz-like sound into various recognizable speech sounds
Articulatory system
- Sound Converter (converter NOT interpreter)
- Collects “heard” aspects of speech & converts them into signals the brain can make sense of. It sends these signals to the brain for interpretation! (the brain extracts meaning)
Auditory system
What are the two roles of the nervous system?
Speaker & Listener
Monitors self for accuracy of spoken messages & monitors listener for signs of comprehension of intended message
