With many functions, too much emphasis on one function causes others to suffer: the colony, a solution -- one day you (a single cell organism) are crawling around and run into another (an amoeba). You like to crawl around, it likes to ingest. So, the two of you team up, form cells or societies and make use of each other"s skills. You compensate for its shortcomings and it compensates for yours. All of this leads to advancements in cell organization and development. Now, multi-celled organisms begin to evolve and adapt to their environments. Now we can take a closer look at the individual cells (neurons) and their components. Let"s examine the neuron and its components: the neuron. The majority of neurons are located in the brain - approx. 100 billion in the brain, although this is debatable. There are three major types of neurons upon which information travels.
