⚖️ Nervous System vs Endocrine System as Coordination Centres
The body uses two types of coordination centre, often working together. Understanding the differences helps you answer questions about why one system is used rather than the other for a particular homeostatic response.
Figure 2: The two coordination systems compared.
| Feature | Nervous System | Endocrine System |
|---|---|---|
| Signal type | Electrical impulses | Chemical hormones in blood |
| Speed | Very fast (milliseconds) | Slower (seconds to minutes) |
| Duration of response | Short-lived | Long-lasting |
| Target | Specific (target organ/muscle) | Widespread (all cells with receptors) |
| Pathway | Nerve fibres (neurones) | Bloodstream |
| Homeostasis example | Shivering reflex (temperature) | Insulin/glucagon (blood glucose) |
