The basic purpose of a neuron is to receive incoming information and, based upon that information, send a signal to other neurons, muscles, or glands. Neurons are designed to rapidly send signals across physiologically long distances. They do this using electrical signals called nerve impulses or action potentials. When a nerve impulse reaches the end of a neuron, it triggers the release of a chemical, or neurotransmitter. The neurotransmitter travels rapidly across the short gap between cells (the synapse) and acts to signal the adjacent cell.
What part of a neuron carries nerve impulses away from the cell body? The axon carries the signal away from the neuron, while the dendrite carries the signal to the neuron. The cell body of a neuron (a nerve cell) receives signals fr â¦ om its neighbors; when prompted thereby to send a signal of it's own, the axon (an extension protruding from the body) propagates that signal electrochemically via an ion pump to other neurons at the terminal synapse (a small gap between one neuron and the next).
