Vedclass · Answer

(B) In electrical synapses,the membranes of pre- and post-synaptic neurons are in very close proximity ($i$ is correct).Electrical current can flow directly from one neuron into the other across these synapses ($ii$ is correct).Impulse transmission across an electrical synapse is very similar to impulse conduction along a single axon ($iii$ is correct).Electrical synapses do not use neurotransmitters; they rely on direct ionic flow through gap junctions ($iv$ is incorrect).Electrical synapse transmission is very fast,often faster than chemical synapses ($v$ is correct).Electrical synapses are indeed rare in our system compared to chemical synapses ($vi$ is correct).Therefore,statements $i, ii, iii, v,$ and $vi$ are correct.
