We humans tend to view cortical mechanisms/functions as the most important, perhaps because we are the species with the largest cortexes. However, one could argue from several perspectives that the lower sensorimotor functions are even more important. Why would someone argue for the latter

It can be argued that the central nervous system is of equal importance to the peripheral system because the actions that signal the brain by means of nerve impulses are carried out.

That is why a central nervous system could not be executed without the innervation of the peripheral nerves to the muscles.

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.
