Vedclass · Answer

(B) synapse is formed by the membranes of a presynaptic neuron and a postsynaptic neuron,which may or may not be separated by a gap called the synaptic cleft.In electrical synapses,the membranes of pre- and post-synaptic neurons are in very close proximity,and electrical current can flow directly from one neuron into the other across these synapses.Impulse transmission across an electrical synapse is very similar to impulse conduction along a single axon.Therefore,the statement that synaptic membranes are 'always' separated by a synaptic cleft is incorrect,as electrical synapses do not necessarily have a synaptic cleft.
