Difference between Sympathetic And Parasympathetic Nervous System
| Sympathetic | Parasympathetic |
|---|---|
| Sympathetic system has shorter neuron pathways, hence a faster response time. | Has comparatively longer neuron pathways, hence a slower response time. |
| Increases heartbeat, muscles tense up. | Reduces heartbeat, muscles relaxes. |
