Answer:
synaptic gap or synaptic cleft
Explanation:
Two neurons communicate with each other at the synapse. At the synapse, the axon terminals of the first neuron of synapse communicate with the dendrites of the postsynaptic neuron. These two neurons are not in physical contact with each other but there is a gap between them. This gap is called the synaptic cleft. The axon of the first neuron of synapse release neurotransmitters in this gap. These neurotransmitters then bind to the receptors present on the surface of dendrites of the second neuron and the nerve impulse is conducted.
