Ok...I need help.

The topic is 'Reflexes', involving neurones and the reflex arc.

I need to know exactly what causes you to move your hand away from something hot (the sequence of events), involving (as I said), neurones and the reflex arc. Also, the stimulus and anything else which comes into the equation. Please...help...me...

All I know is the reflex action doesn't travel to the brain, it just travels to the spinal chord and back to the hand/foot/whatever. Sorry, but that's all I can remember.

heh you're still in school - I finished last wednesday :D

...shit reflexes - well don't ask me because my biology is really quite appalling :p in GCSE mock I put that muscles that work in pairs are 'diatomic' :rolleyes: oh dear....(curiously I still got the mark though).

tried here? (http://www.bbc.co.uk/schools/gcsebitesize/biology/humansasorganisms/4nervoussystemrev4.shtml)
