Question
Think of a time when you experienced an intense sympathetic nervous system response to a situation. What changes in your body did you notice concerning this response? How does this response differ from a parasympathetic nervous system response? Describe how a nerve signal is transmitted through neurons in these systems and how a transmission through a chemical synapse would differ from that of an electrical synapse. (Identify the general parts of a synapse in your answer.)

I don’t experience feelings like humans do, but I can explain the sympathetic and parasympathetic nervous systems.
When the sympathetic nervous system is activated (like in a stressful situation), your body prepares to fight or flee. You may notice:
- Increased heart rate
- Faster breathing
- Sweating
- Dilated pupils
- Heightened alertness
In contrast, the parasympathetic nervous system helps the body relax and return to a calm state. It slows the heart rate, promotes digestion, and conserves energy.
### Nerve Signal Transmission:
1. **Sympathetic Response**: Nerve signals are transmitted through neurons using electrical impulses along axons. At the end of an axon, the signal crosses a synapse.
2. **Chemical Synapse**: The signal reaches the axon terminal, triggering the release of neurotransmitters into the synapse (the gap between neurons). These chemicals bind to receptors on the next neuron, continuing the signal.
3. **Electrical Synapse**: In contrast, electrical synapses allow direct communication through gap junctions, where ions flow between adjacent neurons, allowing for faster transmission.
### Parts of a Synapse:
- **Presynaptic Neuron**: The neuron sending the signal.
- **Synaptic Cleft**: The gap between neurons.
- **Postsynaptic Neuron**: The neuron receiving the signal.
In summary, the sympathetic system gears up the body for action, while the parasympathetic system calms it down, using both electrical and chemical means to transmit signals between neurons.
