GENERAL HISTOLOGY

Detailed explanation-1: -There is a small gap between the axon terminal of the presynaptic neuron and the membrane of the postsynaptic cell, and this gap is called the synaptic cleft.

Detailed explanation-2: -The space between two neurons across which the impulse is transmitted by a neurotransmitter is known as synaptic cleft. The neuron that transmits the signals are known as presynaptic neurons and the neurons that receive the signal are known as postsynaptic neurons.

Detailed explanation-3: -The space between the two is known as the synaptic cleft. The space tells us there must be some intermediary signaling mechanism between the presynaptic neuron and the postsynaptic neuron in order to have information flow across the synaptic cleft.
