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.) Way super super short plss and very simple and easy plss

When I experienced an intense sympathetic nervous system response, I noticed my heart rate increased, my breathing became faster, and I felt a surge of energy (like adrenaline). This is different from the parasympathetic nervous system, which calms the body down, slowing heart rate and promoting relaxation.
In the nervous system, nerve signals are transmitted through neurons using electrical impulses along the axon. When reaching a synapse, the signal can be transmitted in two ways:
1. **Chemical Synapse**: Here, the signal causes the release of neurotransmitters (chemicals) from one neuron to bind with receptors on another neuron. The key parts of a chemical synapse include:
- **Presynaptic terminal** (where neurotransmitters are released)
- **Synaptic cleft** (the gap between the neurons)
- **Postsynaptic terminal** (where receptors detect the neurotransmitters).
2. **Electrical Synapse**: In contrast, an electrical synapse allows direct current flow between neurons through gap junctions, resulting in faster signaling without neurotransmitter release.
So, chemical synapses involve neurotransmitters and a synaptic cleft, while electrical synapses are direct connections that allow for quick transmission.
