Hormones
Carry information and instructions around the body
Act slowly
Act for a long time
Act in a more general way
If the response is really quick
It's probably nervous
If the response lasts for a long time
It's probably hormonal
Nerves need to pass information to effectors really quickly (e.g. pain or information from your eyes telling you about the lion heading your way)</b>
Hormones are too slow to carry messages that need to be passed quickly
When you get a shock, a hormone called adrenaline is released into the body (causing the fightorflight response, where your body is hyped up ready for action)
You can tell it's a hormonal response (even though it kicks in pretty quickly) because you feel a bit wobbly for a while afterwards
Hormones control various organs and cells in the body, though they tend to control things that aren't life-threatening so things like sexual development, blood sugar level, water content, etc.
