Detailed explanation-1: -There is only one axon that projects from each cell body. It is usually elongated and because it carries impulses away from the cell body, it is called an efferent process.
Detailed explanation-2: -axon, also called nerve fibre, portion of a nerve cell (neuron) that carries nerve impulses away from the cell body. A neuron typically has one axon that connects it with other neurons or with muscle or gland cells. Some axons may be quite long, reaching, for example, from the spinal cord down to a toe.
Detailed explanation-3: -The dendrites carry impulses toward the cell body. The axon carries impulses away from the cell body.
Detailed explanation-4: -Each neuron in your brain has one long cable that snakes away from the main part of the cell. This cable, several times thinner than a human hair, is called an axon, and it is where electrical impulses from the neuron travel away to be received by other neurons.
Detailed explanation-5: -An action potential, also called a nerve impulse, is an electrical charge that travels along the membrane of a neuron.
