So that basically implies that the neuron depends on glucose and oxygen that is found in the blood for a steady supply. Now, glucose is brought into the neuron via special type of protein molecules found in the membrane of our cell body known as our facilitative transporter proteins. And unlike most other proteins that transport glucose found in other cells of the body, the proteins in the membrane of the nerve cells do not usually depend on insulin to transport our glucose inside our cell. Now, that's not to say that insulin doesn't actually play an important role in the transportation of glucose into the inside of the cell. What this basically means is our glucose can still be brought into the cell in the absence of insulin. So basically, this is the introduction to our neuron.
