This video is all about the nervous system’s divisions. The nervous system is the control centre of our body and it controls the function either voluntary or involuntary. The nervous system can be divided and subdivided into many divisions on the basis of anatomy or physiology. The nervous system is divided into two main divisions: the central nervous system and peripheral nervous system. The central nervous system is further divided into the brain and the spinal cord.

The main part of the nervous system is the brain which is the control centre of the nervous system. The brain has many divisions for example the forebrain, the midbrain, and the hindbrain while further each of them is subdivided into different parts and division. At the lower level, we have different parts of the brain for example cerebrum (which is further divided into various lobes like frontal lobe, parietal lobe, temporal lobe, and occipital lobe), cerebellum, midbrain, pons, and medulla oblongata. While the midbrain, pons, and medulla oblongata is collectively called the brain stem. The spinal cord is also a part of the central nervous system and helps in the communication between the brain and the peripheral nervous system.

The peripheral nervous system comprised of neurons that are outside of the central nervous system and transfer the signals from the central nervous system to the periphery or vice versa. The peripheral nervous system is further divided into two main divisions that are somatic nervous system and autonomic nervous system.
