How would you go about comparing hormonal and nervous responses in mammals?

In questions like this, you must set out your answer clearly (which makes it easier for the marker to give you marks).
One way of doing this is writing sentences such as:
_____ in the hormonal response, compared to ______ in the nervous response.
Often the mark scheme requires adjectives about both systems for each mark (like one being slow and the other being fast, not just that one is slow).

The main differences in these two systems lie in:
- Signal type
- Transmission
- Response: type, speed, duration
- Effector (what is carrying out the response)

So you could write something like:
Chemical signals carried by the bloodstream cause a response in the hormonal system. Whereas electrical signals carried by nerve cells and chemical signals between nerve cells cause a response in the nervous system.
(This covers signal type and transmission)
The response tends to occur much faster in the nervous system, but may last for a shorter period of time. In the hormonal system the response tends to be slower (as the chemical must be carried in the bloodstream to the target) and lasts for a longer period of time.
(This covers response speed and duration)
The nervous system causes effectors such as glands and muscles to secrete or contract respectively. The hormonal system causes a chemical change in specific target cells.
(This covers response type and effector)
