In my 2-Minute Neuroscience videos I explain neuroscience topics in 2 minutes or less. In this video, I discuss the divisions of the nervous system. The nervous system has two major divisions: central and peripheral. But the peripheral nervous system is further subdivided into the somatic and autonomic nervous system, and the autonomic nervous system is also divided into sympathetic and parasympathetic fibers. All of these are discussed in this 2-minute video.
