Q. Which of the following is correct regarding electrical synapses? I. Pre and postsynaptic membrane neurons are in very close proximity at electric synapse II. Electric current are involved in the transmission of impulses III. Transmission of an impulse across electrical synapses is very similar to impulse conduction along a single axon IV. Impulse transmission is always faster in electric synapse than that across a chemical synapse V. Electrical synapses are rare in our system The correct option is
A) I, II, III and IV
B) I, III, IV and V
C) I, II and IV
D) I, II, III, IV and V
Explanation
There are two types of synapses namely electrical synapses and chemical synapses. At electrical synapses, the membrane of pre and post synaptic neuron are in very close proximity transmission of an impulse across electrical synapses is very similar to impulse conduction along a single axon
