286592 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.

1 Both(A) and (R) are correct but (R) is not the correct explanation of (A)
2 (A) is correct but (R) is not correct
3 (A) is not correct but (R) is correct
4 Both (A) and (R) are correct and (R) is the correct explanation of(A)

286593 Assertion : The resting membrane of the neuron exhibit polarity of charges.
Reason: The outer surface of the axonal membrane possesses a negative charge while its inner surface becomes positively charged.

2 (A) is correct but (R) is not correct
3 (A) is not correct but (R) is correct
4 Both (A) and (R) are correct and (R) is the correct explanation of(A)

286594 Assertion : The brain stem contains centres for controlling activities.
Reason : Brain stem is very sensitive.

286595 Assertion : The imbalance in concentration of $\text{N}{{\text{a}}^{+}},{{\text{K}}^{+}}$ generates resting potential.
Reason : To maintain the unequal distribution of $\text{N}{{\text{a}}^{+}}\And {{\text{K}}^{+}}$, the neurons use electrical energy.
