Long answer question
Answer the question after observing the diagram given below.
Will the impulse be carried by the postsynaptic membrane carried even if one pre-synaptic neuron is there?
a. A pre synaptic neuron when receives an impulse, releases a neurotransmitter into the synaptic cleft which is required to cross the gap between the axon terminal and the next neuron.
b. For further transmission of impulse, a pre-synaptic neuron is required that initiates the release of neurotransmitters that facilitate the movement of impulses across synapses.
