Biology: Edexcel IGCSE, topic 3.5.20
Nervous vs Endocrine System
The central nervous system (CNS) is different to the endocrine system in a few key ways:
Central nervous system (CNS)
- Triggers rapid response.
- Uses electrical signals that are carried by neurones.
- Response is very short.
- Acts on a very precise part of the body.
Endocrine (hormonal) system
- Triggers a slower response.
- Uses chemical messengers that are carried by blood.
- Response can be long-lasting.
- Can act on large areas of the body.
