Impulse transmitters are specialized cells that are responsible for transmitting electrical signals throughout the body. Axons, NERVES, and neurons are all types of impulse transmitters. Axons are long, thin fibers that extend from the cell body of a neuron and carry electrical signals away from the cell body. NERVES are bundles of axons that connect different parts of the body. Neurons are the basic unit of the nervous system and are responsible for receiving and transmitting information throughout the body.
