Neurons may be unipolar, bipolar, or multipolar, depending upon which directions the impulses are carried (characteristics based upon the structure of the neuron). |Multipolar neurons| usually have several |dendrites| to receive impulses, but only one |axon|, to carry the signal away. Bipolar neurons have one |dendrite| and one |axon|, so that ~nerve~ impulses may be received and transmitted in one direction only, from one "pole" of the neuron to the other.
