Define the term synapse in terms of function and structure.
Synapse is the junction between neural cells across which an impulse is transmitted. The axon of one neuron synapses with the dendrites of other neurons. The many-branched, terminal portion of an axon not only may synapse with many other neurons but also may synapse with numerous points on a single neuron. Each terminal branch of an axon ends in a synaptic bouton. A gap called the synaptic cleft separates the pre synaptic membrane of a synaptic bouton from the post synaptic membrane of a dendrite.
