Peripheral nervous system

I was 13 years old when I had my first scientific epiphany. My high school biology class was studying the brain and that day we’d been taught that no new neurons formed during adulthood. I remember reading a copy of MIT's Technology Review magazine that night in my parent's living room. There was a short article about new research on neurogenesis: new neurons formed in some areas of the adult brain. At the time, I was not so much floored by the fact that new neurons formed in adulthood, but that…

Abstract Chronic inflammatory demyelinating polyneuropathy is considered an autoimmune disorder of the peripheral nervous system. It is the chronic form of Guillain-Barre syndrome, the difference between the two diseases is GBS is an acute inflammatory disease of peripheral nerves and most patients recover spontaneously while CIDP requires more attention. The cause of CIDP is unknown it is believed that it may be caused due to the immune response of the body attacking the nerve fibers causing…

The Nervous system is one of the most important parts of the body. It connects all other organs to help them communicate together. This system is made up of the brain, the spinal cord, sensory organs, and nerves that connect organs together. When all of these parts work together, they have control of the body. The brain and the spinal cord are two major organs that make up the central nervous system. The nervous systems relationship with the other systems is giving them the right information…

Multiple sclerosis (MS) is a muscular disease that affects the central nervous system (CNS) which consists of the brain and the spinal cord. This disease was discovered by Dr. Jean Martin Charcot. Eventually, improvements in microscopes helped doctors in the search of understanding the disease. In 1916, a Scottish doctor named James Dawson was able to clearly describe the inflammation after viewing the brain cells of a patient with multiple sclerosis through a microscope. Over the years,…

spinal cord, brain stem, and peripheral nerves form a complex information developing system, acknowledged as the central nervous system. They contribute to performance of conscious and unconscious aspects of life. The mind has an abstract, rational, and conscious process. Conscious mental processes give a flexible, adaptable form of management. Furthermore, bodily functions are ingenious with the physical facets of brain-neurons and brain balance. Central nervous systems are liable for…

significant affects to a patient’s overall quality of life: Whether within the Peripheral or Central Nervous Systems. Neural Engineering is a sub-discipline within Biomedical Engineering that utilizes engineering techniques to understand, repair, replace and even enhance the properties of the neural system. In the field of Neural Tissue Engineering, the practice has been greatly limited to the spinal cord and peripheral nervous system. As such, the main focus of this paper is in the various…

starts in immature nerve cells in the sympathetic nervous system. The autonomic system ( which is part of the peripheral nervous system) is divided into to the parasympathetic system and the sympathetic nervous system. The parasympathetic nervous system controls activities when the body is at rest. The sympathetic nervous system controls involuntary body functions like breathing and digestion. It prepares the body for action. The nerves in this system control the fight-or-flight response. The…

afternoon around 2:30, you 're just sitting at home watching television and life is slowly just passing you by. Even as drift slowly into a stagnant and passive state, your brain is still constantly at work using apart of the nervous system called the automatic nervous system . Your brain is one of the most important parts of your body, it tells every other part of your body what to do, whether we are aware of it or not. So as you sit idle on your couch staring into a picture box, your brain is…

leads to pleasant motives whereas negative leads to unpleasant motives. There are two theories of emotion. ‘James-Lange theory,’ states that emotions arise from peripheral nervous system response, which is interpreted by the central nervous system. ‘Cannon-Bard theory,’ states that emotion-inducing stimuli simultaneously produces peripheral and emotional…

The nervous system makes it possible for animals to know and react to the environment around them. A change or event that evokes a specific functional reaction in an organ or tissue is a stimulus. There can either be an internal or an external stimulus. Internal stimulus being something like hunger or pain, while external is more along the lines of a sound or an odor. The nervous system interprets stimuli and orders other organ systems to respond. The nervous system does so through using sensory…
