An axon is a type of nerve cell that transmits electrical signals from one neuron to another. It is also known as a nerve fiber and is part of the nervous system. Axons are responsible for carrying information from the brain to the rest of the body. The term 'axon' comes from the Greek word for 'AXIS, ' which refers to the way the axon runs along the length of the neuron. A transmitter is an electronic device that sends signals from one place to another. Transmitters are used in many different applications, such as radio and television broadcasting, cellular phones, and satellite communications.
