Neurons are highly specialized for the processing and transmission of cellular signals. Given their diversity of functions performed in different parts of the nervous system, there is a wide variety in their shape, size, and electrochemical properties. For instance, the soma of a neuron can vary from 4 to 100 [[Micrometre|micrometers]] in diameter.<ref>{{cite web |first = Melissa |last = Davies |title = The Neuron: size comparison |url = https://www.ualberta.ca/~neuro/OnlineIntro/NeuronExample.htm |work = Neuroscience: A journey through the brain |date = 2002-04-09 |access-date = 2009-06-20}}</ref>

神经元对细胞信号的处理和传送是高度专业化。鉴于它们在神经系统的不同部分所执行的功能的多样性，它们的形状、大小和电化学特性也有很大差异。例如，一个神经元的胞体的直径可以从4到100微米不等。

*The '''[[Soma (biology)|soma]]''' is the body of the neuron. As it contains the [[cell nucleus|nucleus]], most [[protein biosynthesis|protein synthesis]] occurs here. The nucleus can range from 3 to 18 micrometers in diameter.<ref>{{cite web  |first = Eric H. |last = Chudler | name-list-style = vanc |title = Brain Facts and Figures |url = http://faculty.washington.edu/chudler/facts.html |work = Neuroscience for Kids |access-date = 2009-06-20 }}</ref>
