Directions: In the following questions, a statement of assertion is followed by a statement of reason. Mark the correct choice as:
Assertion : Transmission of nerve impulse across a synapse is accomplished by neurotransmitters.
Reason : Transmission across a synapse usually requires neurotransmitters because there is a small space, i.e., synaptic cleft, that separates one neuron from another.
  • 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.
Correct answer is option 'A'. Can you explain this answer?

Assertion and Reason Explained
The assertion and reason statements in the question relate to the fundamental mechanisms of neuronal communication.
Assertion: Transmission of nerve impulse across a synapse is accomplished by neurotransmitters.
- This is true. Neurotransmitters are chemical messengers that transmit signals across the synaptic cleft from one neuron to another. They play a crucial role in relaying information in the nervous system.
Reason: Transmission across a synapse usually requires neurotransmitters because there is a small space, i.e., synaptic cleft, that separates one neuron from another.
- This is also true. The synaptic cleft is a tiny gap (approximately 20-40 nanometers) between the presynaptic and postsynaptic neurons. Because electrical impulses cannot jump this gap, neurotransmitters are released from the presynaptic neuron and bind to receptors on the postsynaptic neuron.
Correct Explanation Relationship
- The reason provided correctly explains why neurotransmitters are essential for the transmission of nerve impulses across a synapse. The presence of the synaptic cleft necessitates the use of these chemical messengers for communication between neurons.
Conclusion
- Since both the assertion and reason are true, and the reason accurately explains the assertion, the correct answer is option 'A': "If both Assertion and Reason are true and Reason is the correct explanation of Assertion."
This understanding is crucial for grasping neurophysiology, particularly in contexts like the NEET examination.
