35.2 Neuron Structure

We have seen that nerve cells can be classified as sensory neurons, interneurons, or motor neurons. Yet all three receive and transmit information, and all three share the same basic organization. Neurons have extensions that receive information and relay it to the cell body. They also have other extensions that transmit information away from the cell body. Although all neurons share this basic plan, they differ remarkably in size and number of extensions, according to their specific function.
