The difference between nerves and hormones
- Nerves
- Very FAST message
- Act for a short time
- Very precise area
- Electrical message (from the electrical impulse)
- Some reactions require immediate attention (eg pain signals) therefore we need nerves. Hormones would be too slow.
- Hormones
- Much slower message
- Act for a long time
- More General area
- Chemical message
- But sometimes you get a longer response eg in shock Adrenaline is released causing fight or flight response where your bod is excited for action
