284579 Statement (S) An action potential occurs in the membrane of the axon of a neuron due to influx of \(\mathrm{Na}^{+}\)ions.
Reason (R): The action potential occurs when the depolarization reaches a threshold potential of \(+55 \mathrm{mV}\).
The correct answer is

1 Both (S) and (R) are correct but (R) is not correct explanation to (S)
2 Both (S) and (R) are correct and (R) is the correct explanation to (S)
3 (S) is correct but \((R)\) is not correct
4 (S) is not correct but (R) is correct

284582 Statement (S) : In brain stem, the pons is called as pneumotaxic centre with an ability to moderate the functions of the "respiratory rhythm centre"
Reason (R) : Neural signals from this centre can reduce the duration of expiration, thereby alter the respiratory rate.
Correct answer is

1 Both (S) and (R) are correct but (R) is not the correct explanation to \((S\)
2 Both (S) and (R) are correct and (R) is the correct explanation to \((\mathrm{S})\)
3 (S) is wrong but (R) is correct
4 (S) is correct but \((R)\) is wrong

284584 Select the incorrect statement regarding synapses:

1 Impulse transmission across a chemical synapse is always faster than that across an electrical synapse.
2 The membranes of presynaptic and postsynaptic neurons are in close proximity in an electrical synapse.
3 Electrical current can flow directly from one neuron into the other across the electrical synapse.
4 Chemical synapses use neurotransmitters.
