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.
â¢ Receives signals from other cells and sends them toward the axon. â¢ Sum up, or integrate, the incoming signals. â¢. Axon. The transmitting or conductive region of the neuron. â¢. The axon generates an action potential, an outgoing signal also called a nerve impulse, and conducts it to the next cell.â¢ Label the parts of this neuron: â¢ Neurons receive and integrate signals at one location and transmit an action potential at another location.Page 6. In most neurons, the cell body, or soma, is located centrally. â¢ Multiple similar processes, called dendrites, extend from the soma, forming a structure resembling the branches of a tree. â¢ A thin single process, called the axon, also extends from the soma.
