Impulse Direction

Refers to the path that an electrical impulse follows, especially within the nervous system.

Of a neuron, a cytoplasmic extension that receives chemical signals sent by other neurons.

Axon

Of a neuron, a cytoplasmic extension that transmits electrical signals along its length and secretes chemical signals at its endings.
