Question

Which of the following statements is incorrect regarding electrical synapses?

(a) Transmission of signals is faster than chemical synapses

(b) Pre and postsynaptic membranes are in very close proximity

(c) They are very common in our system

(d) Electrical synapse can flow directly from one neuron to another

I have been asked this question during an interview.

This is a very interesting question from Human Neural System topic in portion Neural Control and Coordination of Biology – Class 11

Answer 1

Right answer is (c) They are very common in our system

The explanation: Electrical synapses are very rare in our system. At electrical synapses, the membranes of pre and post synaptic neurons are in very close proximity. Impulse transmission across an electrical synapse is always faster than chemical synapse.
