The Central Nervous System

The central nervous system is a very important section of the nervous system of the human body. The central nervous system has two parts; first one is a brain and the second one is a spinal cord. The central nervous system is considered as the central system of a human body. I will discuss the brain: a part of the central nervous system, its functions, and disorders [Boundless (2015)]. The Brain is the most important part of a nervous system. It controls the whole system of a body and sends signals to each and every part of human body. The brain in human body works fast and as anything happens in body signals from that part are sent to the brain and through brain human realizes the movements and thoughts in the body. It works as a central unit of a human body. It is divided into various parts that are front lobe, parietal lobe, occipital lobe, temporal lobe and brain stem [BTBUDDIES (2011)]. The disorders of the brain are discussed here. The disorders include trauma, stroke; that stops the supply of oxygen to the brain, different diseases, cancer, viral infections, and abnormal growth etc. [Brindles Lee Macon (2012)].

The peripheral nervous system works as a connection in a human nervous system and it connects all parts of the human body to the central nervous system through different nerves. It provides sensory feels to the central nervous system of the body. It transmits the sense of anything that happens in the body to the central nervous system that is brain and this transmission is done through nerves. The parts of the peripheral nervous system are sensory nervous cells and motor nervous cells. The sensory nervous cells create an informational impact on the central nervous system, and the motor nervous cells carry this message to the central nervous system. The part I will discuss the sensory nervous cells. It is the most important part because it creates an...
