Motor Control Flashcards
What systems contribute to motor control
Visual
sensory
Vestibular
motor
Where is the cerebellum located
Posterior to the brainstem
What is the cerebellum get input from
The spinal cord
cerebral cortex
sensory systems
What does the cerebellum have a role in
Error detectionable-able to receive info from the body and modify and adjust movement
cognition-predicting prepare functional responses from the environment
What is the role of the basal ganglia
Prepare and execution of movement
visual
muscle tone
initiation of movement
What does a lesion in upper motor neuron result in
Spasticity
Where upper motor neuron’s located
From the brain to the spinal cord
Where are lower motor neuron’s located
From the spinal cord and out
What does a lesion in lower motor neuron’s results in
Flaccidity
What is the newer theory of motor control
Movement is an interaction between individual task and environment
each system influences the other and is dynamic
What is paresis
Motor weakness
Can be mild to severe
Inability to recruit motor units to generate movement
Where does paresis occur
Umn
What is a synergy pattern
Gross patterns of movement that is involuntary
flex or extension
unable to isolate movement
What is normal muscle tone
A continuous state of mild contraction
What does normal muscle Tone do
Allows for coactivation for stabilization
allows for movement against gravity
allows for maintaining position if passively placed
move from stability to mobility
isolation
to respond to passive movement with slight resistance
