The correct Answer is:
**Step-by-Step Text Solution:** 1. **Understanding the Question**: The question asks for the term that describes the microscopic gap between two adjacent neurons where nerve impulses are transmitted. 2. **Identifying the Key Term**: In neuroscience, the gap between two neurons is crucial for the transmission of nerve impulses. This gap is not a physical connection but rather a space that allows for chemical communication. 3. **Recognizing the Correct Term**: The term used to describe this gap is "synapse." A synapse is where the transmission of signals occurs via neurotransmitters. 4. **Explaining the Process**: When a nerve impulse reaches the end of a neuron, it cannot directly pass to the next neuron. Instead, it triggers the release of neurotransmitters, which are chemicals that cross the synaptic gap to transmit the signal to the next neuron. 5. **Conclusion**: Therefore, the correct answer to the question is "synapse." **Final Answer**: The microscopic gap between a pair of adjacent neurons over which the nerve impulses pass is called a "synapse." ---
