motor control Flashcards
what are movements?
simple reflexes with brief muscle activation (blinking, hiccup, twitch)
What are acts?
action patterns, are complex, sequential movements (honking horn, writing name)
what is a motor plan?
set of muscle commands established before the action occurs
what is the only reason we need the brain
to move and guide movement
What do the two control mechanisms do?
optimize accuracy and speed
what does an open-loop control do?
maximizes speed
what are ballistic movements?
rapid -completed no matter what sensory feedback is received
what is closed-loop control?
maximizes accuracy-information from what is being controlled flows back to the controlling device
what is ramp movements?
are slower, sustained motions guided by feedback
skeletal muscles do?
power movement
spinal cord do?
control skeletal muscles
what does brainstem do?
integrates motor commands
what does the primary motor cortex do?
initiates commands for action
what does the nonprimary motor cortex do?
initiated cortical processing
