Question

Transmission of the nerve impulse across a synapse is accomplished by the

• A. movement of $N{a}^{+}$ and $K^{+}$
• B. release of neurotransmitters
• C. both of these are correct
• D. neither of these is correct

Answer 1

The correct option is B release of neurotransmitters

The receptors receive the neurotransmitters. These neurotransmitters stimulate action potential in the postsynaptic cell. Thus, transmission of nerve impulses across a synapse is through the release of neurotransmitters by the axon.

So, the correct answer is 'release of neurotransmitters'.
