Explanation:
Detailed explanation-1: -synapse, also called neuronal junction, the site of transmission of electric nerve impulses between two nerve cells (neurons) or between a neuron and a gland or muscle cell (effector). A synaptic connection between a neuron and a muscle cell is called a neuromuscular junction.
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: -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.
