Neurons are sorted by how many branches, called processes, grow out of the cell body. Dendrites bring messages in, the cell body keeps the cell alive, and the axon sends the message out. Pick a type to compare.
Tap any part of the neuron to see what it does.
Simplified drawings, not to scale; real axons can be thousands of times longer than the cell body is wide. Some textbooks call pseudounipolar neurons “unipolar.”
