063 The Divisions of the Nervous System

In this episode, Leslie Samuel discusses the divisions of the nervous system, including the central and peripheral nervous systems. The central nervous system, comprising the brain and spinal cord, is the processing center, while the peripheral nervous system connects it to the limbs and organs. The peripheral system is further divided into the somatic and autonomic systems, with the latter controlling involuntary functions. The autonomic system includes the sympathetic and parasympathetic systems, responsible for stress responses and relaxation, respectively. The video concludes with an invitation to explore more resources on Interactive-Biology.com.
