True.
A neuron is nerve cell. It is considered the functional unit of the nervous system and it carries electrical impulses to the appropriate part of the nervous system or interprets the impulse and allows a response.
The electrical impulse or message is carried through the fibrous extensions of the neuron called dendrites to the cell body. It passes through the cell body via the axon and finally to the end brush , a collection of fibers that extend off the axon.
The electrical impulse then triggers a release of chemicals which permit the impulse to jump through the synapse, the space between the axon of one neuron and the dendrites of the next neuron.
