In fact, we have many more of these other cells found inside our nervous system than our neurons. Now, all these other cells fall into a category that we call neuroglia. So neuroglia, also known as glial cells, are all the other cells aside from the neuron found inside our nervous system. And the purpose of these other cells, the purpose of neuronglia is to basically increase the effectiveness and functionality of these neurons found inside our nervous system and to support these neurons in different ways. So that's exactly why neuroglia, or glial cells, are commonly known as the support cells of the nervous system. Now, generally speaking, our nervous system can be broken down into two divisions.
