Detailed explanation-1: -Synapse is the functional region of contact between two neurons. It is the structural and functional unit of nervous system.

Detailed explanation-2: -A neuron has three main parts: dendrites, an axon, and a cell body or soma (see image below), which can be represented as the branches, roots and trunk of a tree, respectively.

Detailed explanation-3: -Synapses connect neurons in the brain to neurons in the rest of the body and from those neurons to the muscles. This is how the intention to move our arm, for example, translates into the muscles of the arm actually moving.

Detailed explanation-4: -Therefore, the area of contact between two neurons is called the synapse.

Detailed explanation-5: -Introduction: The brain is made up of about 86 billion nerve cells (also called “neurons"). A neuron has 4 basic parts: the dendrites, the cell body (also called the “soma"), the axon and the axon terminal.
