Assertion and Reason
Directions: The following question has two statements, Assertion and Reason.
Answer the question by choosing any one of the four responses.
Assertion: Brain and spinal cord are called modulators.
Reason: Their neurons receive a stimulus and set up a sensory impulse.
If both Assertion and Reason are true and Reason is the correct explanation of Assertion
If both Assertion and Reason are true but Reason is not the correct explanation of Assertion
If Assertion is true but Reason is false
If Assertion is false but Reason is true

The ions across the resting membrane are regulated by the sodium-potassium pump. The gaining of positive charge on the inner surface and negative charge on the outer surface of the membrane is maintained by the transport of
the following processes:
Polarisation of the membrane of a nerve fibre
Depolarisation of the membrane of a nerve fibre
Conduction of a nerve impulse along a nerve fibre
(d) Transmission of a nerve impulse
across a chemical synapse
