Assertion:Electrical synapses are rare in our system.
Reason:Impulse transmission across an electrical synapse is slower than that across a chemical synapse.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both assertion and reason are true but reason is not the correct explanation of assertion.
C. If assertion is true but reason is false.
D. If both assertion and reason are false.

Explanation

To analyze the given assertion and reason, we will break down the statements step by step.

### Step 1: Understand the Assertion
- **Assertion**: "Electrical synapses are rare in our system."
- This statement is true. In human physiology, electrical synapses are indeed less common compared to chemical synapses. Electrical synapses allow direct electrical communication between neurons, but they are not the primary means of communication in the human nervous system.

### Step 2: Understand the Reason
- **Reason**: "Impulse transmission across an electrical synapse is slower than that across a chemical synapse."
- This statement is false. Electrical synapses transmit impulses faster than chemical synapses. In electrical synapses, the electrical signal is transmitted directly through gap junctions, allowing for rapid communication. In contrast, chemical synapses involve the release of neurotransmitters, which takes more time due to the processes of vesicle fusion and neurotransmitter diffusion.

### Step 3: Conclusion
- Since the assertion is true and the reason is false, we conclude that the correct answer to the question is **C** (Assertion is true, Reason is false).

### Summary
- **Assertion**: True (Electrical synapses are rare in humans).
- **Reason**: False (Impulse transmission across electrical synapses is faster than chemical synapses).
- **Answer**: C (Assertion is true, Reason is false).
