Document Summary
The nervous system topic #6 - closed-loop motor control part 1. Closed-loop model of motor control - system detecting errors in on-going movement: sensory organs are continually detecting and adjusting for errors in the environment in order to carry out a system goal, a. Including system goal, the ultimate position you want to be in: b. Planning of movement: c. instructions: effector level. Information sent to spinal level, going to alpha motor neurons and then extrafusal muscle fibres that will perform the system goal: d. output: environment. Take environment into consideration for system goal can be achieved. Monitor the correctness of movement you are using to reach system goal: the closed-loop model of motor control uses afferent and efferent pathways. Afferent pathways are ascending sensory cortical commands from the spinal cord to cortical or subcortical structures that can be used by higher motor systems to adjust or resend motor command to efferent pathway.
