Which of the following statements is TRUE with regard to the motor control hierarchy?
A. The local level of the motor control hierarchy includes the premotor and primary motor regions of the cerebral cortex, as well as the alpha motor neurons and muscle fibers themselves.
B. The highest level of the hierarchy of motor control includes the frontal lobe cortex, the primary motor cortex, muscle sensory receptors, and the basal nuclei.
C. Reflexes that include local-level receptors and muscle fibers cannot occur without input from the higher centers of the motor control hierarchy.
D. The highest level of the hierarchy of motor control is composed entirely of areas of cerebral cortex, and its main purpose is to create a conscious plan to move that depends on the initial position of the parts of the body in space.
E. Neurons of the middle level of the hierarchy integrate afferent information with signals from higher center command neurons to create a motor program-a pattern of neural activity required to properly perform a desired movement.
