Summary / Human nervous system

The video tutorial explains the nervous system, which is responsible for communication and control of body functions. It is composed of neurons and divided into the central nervous system (CNS) and peripheral nervous system (PNS). The CNS includes the brain and spinal cord, with the brain controlling voluntary movements and balance, and the spinal cord handling reflex actions. The PNS consists of cranial and spinal nerves, which connect the CNS to the rest of the body. The tutorial provides a detailed overview of these components and their functions.
