Explanation:
Detailed explanation-1: -Answer and Explanation: The option that is true is option (c). The synapse is simply the gap that exists between the axon terminal of one nerve cell and the dendrites of another nerve cell. In the axon terminal, or pre-synaptic region, many neurotransmitters are packaged into vesicles.
Detailed explanation-2: -Electrical synapses are rare in our system. In electrical synapses, the synaptic cleft is narrow only 0.2 nm. Whereas the synaptic cleft between the chemical synapse is wide and hence impulse transmission through an electrical synapse is faster than chemical synapses.
