The nerve cell outwardly appears to be a mere chemical and biological unit that somehow carries thought processes. This fascinates me.

Guide to Nerve Cells

Neuron Structure - NIHThe complete human nervous system is composed of hundreds of billions of signal generating and processing network units called “neurons.” Each neuron includes a nucleated control center or nerve cell, complete with fingerlike structures called “dendrites” that provide a large receptive surface for incoming signals. The neuron also includes a long threadlike “axon” that carries output signals away. Signals are propagated between neurons across spatial gaps called synapses by charge-carrying chemical ions. Because of the complex shape and physiology of nerve cells, structure and function can be difficult to understand. Informative Bright Hub articles discuss these topics and the health issues that arise from cellular malfunction.
