This great variability (there are
over 200 different kinds of neurons) means that some neurons deviate from the
For example, some axons may form synapses directly
with another neuron’s cell body, or even with its axon.
cell bodies also vary widely both in size (small, medium, large, and giant) and
in shape (star-shaped, fusiform, conical, polyhedral, spherical, pyramidal).
geometry of a neuron’s dendrites and axon also vary tremdously with its
role in the neural circuit.
