1.01 - Introduction Flashcards
What is Physiology?
The function of a living organism and its components
How it works
What is Anatomy?
The structure of an organism.
The parts
What are the three components of Speech Motor Control?
Cognitive Linguistic Processes
Sensorimotor Planning & Programming
Neuromuscular Execution
What do Cognitive Linguistic Processes generate?
Intent
Verbal symbols
What do Cognitive Linguistic Processes organize?
Verbal Symbols
What do Cognitive Linguistic Processes retain in memory?
Intent
Verbal Symbols
Where are Cognitive Linguistic Processes primarily based?
Cortically
What does Sensorimotor Planning/Processing translate?
Verbal symbols into sensorimotor score (the instructions)
What does Sensorimotor Planning/Processing designate?
Muscle activation patterns
What does Sensorimotor Planning/Processing store?
Expected feedback
Where is Sensorimotor Planning/Processing primarily based?
Cortically
What is Neuromuscular Execution?
2
The activation of motor neurons
Muscle contraction & movement
What does Neuromuscular Execution generate and regulate?
Subglottal pressure
What does Neuromuscular Execution modulate by moving the articulators?
(4)
Position
Shaped
Cross-sectional area
Constrictions over time
What is the acoustic output of Neuromuscular Execution?
Speech
Speech originates in the _____.
Cortex
Speech ______ begins when the muscles of the speech mechanism are innervated by _____ (located in the brainstem) which are part of the PNS.
Movement
Cranial nerves
What three things are the pathways from the cortex to the brainstem responsible for?
Regulating proper muscle tone
Storing and scaling the motor programs
Monitoring and correcting the movements
We watched a video of a man with what syndrome? What is a hallmark of that syndrome?
Moebius
Impaired muscle execution
What are two impairments of the speech mechanism?
Paralyzed vocal cords
Cleft Palate
