Which of the following lists the hierarchy of motor control from lowest to highest level of control? a) precommand level, projection level, segmental levelb) projection level, precommand level, segmental levelc) segmental level, precommand level, projection leveld) segmental level, projection level, precommand level

   D)  Segmental level, projection level, precommand level

Explanation: The hierarchical organisation of the motor control system is only one aspect, besides it there is a parallel one. The motor control system is responsible for regulating movement and as such is crucial for the body's motility, which includes directional movement and reflexes. Of course, motor control only exists in organisms that have a nervous system.

As for the hierarchy of the motor control system, the lowest in the hierarchy is the segmental level. It consists of reflexes and parts of the nervous system in charge of automatic movements.

Second in the hierarchy from the lowest to the highest is the projection level and helps in the functioning of the segmental level, i.e, for the regulation of reflexes and for monitoring the multi neuronal system.

The highest level is the precommand level, which is responsible for controlling the output impulses that control the finest, most precise movements of the body, responsible for starting and stopping movements, regulating the muscles, and preventing unwanted movements.
