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. We have the central nervous system, which includes the brain and the spinal cord and we have the peripheral nervous system, which includes everything else. And these two divisions themselves contain their own different types of neuroglia. So let's discuss the different types of neuroglia in the central nervous system as well as in the peripheral nervous system.
