7A: The very fact that you are able to understand this sentence means that neurons in your brain (85 billion in total) are talking to each other. Neurons are the living substance of the nervous system, which extends beyond the brain to the spinal cord and peripherally, allows you to think and process, make decisions, stand up straight, maintain your heart rate, rest and digest. You will come to appreciate the structure and function of the nervous system as we delve into its anatomy and physiology, from the gray and white matter to the cerebellum to the neurons.
