Feedback:
An axon is an extension that carries impulses away from the neuron cell body. Dendrites are short, often highly branched extensions of the cell body. The synapse or synaptic cleft is the junction, or space, between the axon of one neuron and the dendrites of the next. A neurotransmitter is a chemical released by the axon that enables nerve impulses to cross the synapse and reach the dendrites.
