Structure And Function Of the Living Organisms: Human nervous system

The video tutorial explains the nervous system, which is responsible for communication and control in the human body. 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 acting as the control center, comprising the cerebrum, cerebellum, and medulla oblongata. The spinal cord facilitates reflex actions. The PNS consists of cranial and spinal nerves, which connect the CNS to the rest of the body.
