In this question, we're asked, why should autonomic nerve systems be studied first? and i would say that this is because there is a, like, sort of a discrete, simple arc to the way that these autonomic nerve systems are wired up.

For instance, let's say you feel cold.

So the thermoreceptors in your skin as well as your other cells are going to send nerve impulses, aferent nerve impulses, to your hypothalamus, and then your hypothalamus will send inputs to your motor neurons after some relays or interneurons.

The specifics aren't important here, but essentially we have an aferent input from our thermoreceptors, and then up in our brain, our central nervous system, we have an efferent output, which goes to our motor neurons or our neurons that control our muscles that cause us to, for instance, shiver in the case that you're cold.

This is much more simplified than, for instance, trying to understand directed movement...
