10-Minute Neuroscience: Divisions of the Nervous System

In this video, I discuss the divisions of the nervous system starting first with the central and peripheral nervous systems, then moving to the subdivisions of the peripheral nervous system: the autonomic and somatic nervous systems. I cover the three divisions of the autonomic nervous system: the parasympathetic, sympathetic, and enteric divisions. In the first half of the video, I provide an overview of these systems, and in the latter half I discuss the anatomy and physiology of the peripheral nervous system more in depth.

Key points:
00:00 Introduction

3:55 Sympathetic nervous system
4:48 Parasympathetic nervous system
5:42 Enteric nervous system
6:58 Somatic nervous system anatomy
8:26 Autonomic nervous system anatomy & physiology
