Document Summary
High motor control: concerned with strategy, association areas of the cortex and basal ganglia, also involves area of brain involved with memory. Middle control: motor cortex itself and cerebellum, tactics. Low: brain stem and spinal cord, execution. Hierarchal control over movement: starts in the cortex and ends up with movement in the muscles. Motor output guided by sensory input: tons of sensory input, rely a lot on vision and other senses that let us know about space, also rely on systems that allow us to know where our limbs are. Learning changes motor control: location of control, when we first learn something, motor movement is controlled by higher centres of the brain, once it becomes habitual, control happens lower down in. Final common pathway of movement, for movement to actually happen occurs in alpha motor neurons: leave from ventral root of the spinal cord, ventral root is motor output.
