Vedclass · Answer

(B) nerve impulse is transmitted from one neuron to another through junctions called synapses. There are two types of synapses: electrical and chemical.In electrical synapses,the membranes of pre- and postsynaptic neurons are in very close proximity,allowing electrical current to flow directly from one neuron to the other. Therefore,statement $(I)$ is correct and statement $(II)$ is incorrect because there is no synaptic cleft in electrical synapses.Impulse transmission across electrical synapses is very fast,similar to conduction along a single axon. Therefore,statement $(III)$ is correct.Electrical synapses are rare in the human system,making statement $(IV)$ incorrect.Thus,only statements $(I)$ and $(III)$ are true.

True about electrical synapses:
$(I)$. Pre and postsynaptic neurons are in very close proximity.
$(II)$. Pre and postsynaptic neurons are separated by a synaptic cleft.
$(III)$. Impulse transmission is very fast.
$(IV)$. Electrical synapses are common in our system.
