Detailed explanation-1: -Synapse is the gap between dendrite ends and axon terminals. This is the gap in which neurotransmitters are released for further transmission of nerve impulses to successive neurons.
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: -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-4: -In the human body, nerve cells or neurons are the largest cells. The physical gap or space present between two neurons is called the synaptic cleft.
