Document Summary
Brain stem, spinal cord cord)! leg, etc ! Look at how the brain controls movements! When making a movement there are different levels of motor planning and preparation that are necessary in order to carry out that movement ! Start of with a low level of function: this is the actual motor pattern control of the muscles that allow the movement to occur ! This low level of execution is controlled by the lower brain area (brain stem and spinal. Example: motor pattern control that allows a baseball pitcher to extend his arm, retract one. Then there"s the middle level which is entails speci cities of the movement ! Controlled by the motor cortex and cerebellum! Example: how the ball is thrown - force, height, distance ! experiences, present situation, and a higher level of strategic planning ! Controlled by neocortex and basal ganglia ! Lot of memory experience and visual input involved in this higher level of planning !
