i was wondering if somebody could expalin how the reactions goes through the body? i know some, that there is nerv impulses that goes to the brain and spinal cord but i don't know the name of the system nor the name of the different nerves.

i have looked in my biology book with no succes (strangely) anyway i would really appreciate if somebody could help me.

The nervous system? action potentials? why do you need to know names of different nerves? narrow it down a bit and i'll be happy to help.

The motor or neurone functions?

What do you mean by motor or neurone functions? I thought it was motor/sensory etc. Neurones are just the basic building block...?

Ummm

There's the stimulus (light, heat, whatever) that's picked up by a receptor (in skin or eye or whatever). That goes through a sensory neurone to the Co-Ordinator (either the brain or spinal cord) which sends a message through a motor neurone to the effector (muscles in whatever part of body) to make the response (hand moved away from hot thingy).

I think...

it is motor/sensory. what is the system called that the brain and spinal cord make?

The nervous system, which is divided into the Somatic and Autonomic (Sympathetic and Parasympathetic) nervous systems.

I thought that in the case of the reflex arc, the action potential bypasses the brian and is only regulated by the spinal nerves?

you are confusing me a little, am not very good at biology so i apologise for my stupid questions but is it so that the refelxes and reactions uses the same system and that reflexes is just faster?

It is called the central nervous system (or CNS for short), not just the 'nervous system'.

For the somatic reflex arc, the impulse does bypass the brain and is passed through an interconnector neurone in the spinal cord which then relays this to the correct effector (a muscle or gland).

I dont know how much detail you need to go into so Ill leave it at that..

They're the same thing. But some, such as the knee jerk reflex and response to pain are faster because they are dealt with unconsciously by the spinal cord rather than going into the brain and us having to think about them, even for a split-second.
