ANATOMY

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 synaptic cleft-also called synaptic gap-is a gap between the pre-and postsynaptic cells that is about 20 nm (0.02 ) wide. The small volume of the cleft allows neurotransmitter concentration to be raised and lowered rapidly.

Detailed explanation-3: -The point of transfer or the junction from where the electrical signal is transmitted from one neuron to another is known as synapse. The space between two neurons across which the impulse is transmitted by a neurotransmitter is known as synaptic cleft.
