Assertion: The axonal membrane of the neuron is more permeable to sodium ion ( Na+) and nearly impermeable to potassium (K+).
Reason: In a resting state neuron does not conduct any impulse.
(a) If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
(b) If both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion.
(c) If Assertion is correct but Reason is incorrect.
(d) If both the Assertion and Reason are incorrect.
(d) If both the Assertion and Reason are incorrect.
Explanation:
The axonal membrane of neuron is more permeable to potassium ions (K+) and nearly impermeable to sodium ions (Na+). In a resting state neuron does not conduct any impulse. In the resting state the period during which a neuron is not conducting the fluids outside the cell membrane carry a relatively high positive charge. The fluids inside the cell membrane. Carry a less positive, or relatively negative, charge.
