Explanation:
The motor cortex is part of the central nervous system and is where all kinds of signaling and many more functions are programmed. The cortex is what sends the signals to the preganglionic neurons, and this is transmitted to the postganglionic neurons where the stimulus is finally transmitted through the motor plate in the muscles.
This whole process is considered as a perfectly planned system, so it is difficult to say or decide which of the two is more important.
