The nervous system is a network of cells that take messages from the brain and spinal cord to other parts of the body. The nervous system is made up of the Central Nervous System and the Peripheral Nervous System. The Central Nervous System has two main parts; the brain and the spinal cord. While the Peripheral Nervous System has the Somatic and the Autonomic Nervous systems included within it. The Central NS is broken down by two parts the brain and the spinal cord. The brain is protected by the scull and has a mushroom like shape. The brain has four main parts: the brain stem, cerebrum, cerebellum, and the diencephalon. The brain I the main organ of the Central NS. The average size of a human brain is between 1.3 and 1.4g and …show more content…

This lobe is also located in the cerebral hemisphere. The parietal lobe focuses on comprehension, language, reading. It also monitors all sensory comprehension. The parietal lobe has two parts. The sensory cortex and motor cortex. The sensory cortex, is located in the front part of the parietal lobe, it receives information from the spinal cord about the different positions of the various parts and how they move. This area of the brain affects area 's like sense of touch and relays if there is pain or pressure to different parts of the body. The motor cortex 's main function is to monitor and control movement of the body. It is located in the top, middle portion of the …show more content…

A person cannot live without a brain stem. A person 's heartbeat, blood pressure and breathings all originate from the brain stem. The parts of the brain that make up the brain stem are the mid brain, pons and the medulla. The mid brain, which is also known as the mesencephalon are comprised of the tegmentum and the tectum. These parts regulate body movement, vision and hearing. The pon 's portion of the brain stem is in the hind brain and it connects the cerebellum to assist with posture and other body movements. The pon 's also gives a person a level of consciousness necessary for sleeping. The last section might be the most important piece. The medulla is the section of the brain stem that maintains the vital body functions such as a person 's heart rate and breathing. So what about a persons mind? How does the mind relate to all these body parts and functions. The mind always relates in mental processes. It also functions through thought and a persons consciousness. The brain on the other hand is about matter and different parts that all have roles and responsibilities. The long time debate about mind, body and soul can be summed up by asking the question of which one of these is in charge. Are each of these different? Are they the same? Or how do they
