There are two major subdivision of the nervous system, the Central nervous system (CNS) which consist of the brain and the spinal cord and the Peripheral nervous system(PNS) consisting of the neutral tissues outside the brain and the spinal cord. The Central Nervous System integrates and coordinates all bodily functions, process all incoming messages and send commands to different body parts. Sending and receiving messages through the spinal cord and the part of the spinal column called a trunk line, which contains neurons that connect to the Peripheral Nervous System. The Peripheral Nervous System provides the Central Nervous System with information from sensory receptors, relays messages from the brain to the body's organs and muscles. there are two subdivisions of the Peripheral Nervous System is the Somatic Nerve System which regulates the body's skeletal muscles and controls voluntary actions. The Automatic Nervous System sustains basic life functions like breathing, digestion, arousal, controlling the bodies involuntary motor responses and can be broken down into two parts. "The ANS must work even when you are asleep and it sustains life processes during anesthesia and prolonged coma states." (Zimbardo, and Richard 71). The Sympathetic Division is the body's response in emergency situations, the fight or flight reactions. The Parasympathetic Division controls the body's routine functions and is considered the housekeeper because it cleans out the unwanted nerves.
The Brain is the most important part of the central nervous systems and have three interconnected layers, the Brain Stem, The Limbic System and the Cerebrum. The inter most structure of the brain that regulates the bodies life processes and the internal state ...

... cortex located in front of the central sulcus , the upper part of the motor cortex controlling the actions of the lower bodies voluntary muscles, and the lower motor cortex controlling the actions of the uppers bodies voluntary muscles . right behind the central sulcus , on the left and right side of the parietal lobes is the somatosensory cortex which is responsible for the processing the information about temperature, touch, and pain. The auditory cortex is in the temporal lobes and each auditory cortex receives information from both ears. The majority of the Cerebral cortex is devoted to interpreting and integrations information , only a small amount is devoted to processing sensory information. the assocation cortex helps in the planning and decision making process, combining sensory information in order to have an appropriate response to the environment.

(VZV) causes it. Varicella attacks the human’s nervous system and debilitates it. Like many viruses, VZV, enters the body through airborne viral particles from another infected person. “The new host breathes in the virus, which enters the mucous membrane in a person’s respiratory tract and begins to spread without its envelope from cell to cell” (Dougherty, 2002). Every virus has a specific cell it adheres to and attacks in order to invade the human system, VZV, attacks T cells. “The virus invades T-cells
For some time researchers have focused mainly on the sympathetic nervous system and have neglected the Autonomic nervous system. Being that the Autonomic nervous system is that in which is comprised of the sympathetic, parasympathetic, and enterie nervous system one would assume more information would be allotted to this important function of the body. Though the Autonomic nervous system does not provide neural control of the skeletal muscle, it in its own right, it still is very important to the
wellness. Examples of these adverse effects are developmental disabilities, interruption of human growth and development, and depletion of the central nervous system in a child (Overview, n.d.). As noted by Overview (n.d.), “When absorbed into the human body, lead affects the blood, kidneys and nervous system. Lead’s effects on the nervous system are particularly serious and can cause learning disabilities, hyperactivity, decreased hearing, mental retardation and possible death” ( p.
neurologists to explain what the nervous system is, how would typical neurologists respond to such a question? For the most part, patients ' question on what is the nervous system maybe a simple question for neurologists. In this instance, neurologists possibly explain to patients that the nervous System serves as a communication network that operates and coordinates the body 's activities. Operating and coordinating the body 's activities includes the nervous system to monitor thoughts, learning processes
Johnna Casey COMM 101 12:00 10/18/2017 Preliminary Outline Specific Purpose: To inform my audience of the effects of caffeine on the human body. Central Idea: After consuming caffeine, the central nervous system is stimulated, resulting in a wide array of both positive and negative effects on the human mind and body. I. Introduction A. I would venture to say that most of us in this room like to start our day with a cup of coffee. It’s delicious, energizing, and relatively convenient with the campus
but there are several methods through which physical therapy and technology can help patients with a spinal cord injury. A spinal cord injury refers to any traumatic injury to the nervous tissue that runs throughout the spine. Spinal cord injuries can be in one of two basic types, incomplete, or complete (A brief overview). In a complete spinal cord injury there is a total loss of function in everything below the area of the injury. In an incomplete spinal cord injury the patient retains some function
http://emedicine.medscape.com/article/315632-overview These references go into detail about Guillain-Barre Syndrome from the pathophysiology to the causes and treatments. Guillain-Barre Syndrome is a disorder that attacks the peripheral nervous system. The disorder is abbreviated as GBS. GBS is also known as Guillain-Barre-Strohl syndrome, Landry’s paralysis, and acute inflammatory polyneuropathy.” http://emedicine.medscape.com/article/315632-overview” Because it is not currently clear if there is
genotype. These changes may last through generations of cell divisions. Although it was once thought that there was no new generation of neurons in the nervous system, studies have shown that the brain retains neural stem cells (NSCs) into adulthood, and neurogenesis continues to occur. Neural stem cells (NSCs) are the initial cells found in the nervous system and differentiate into the main cell types: oligodendrocytes, astrocytes and neurons. There are three epigenetic mechanisms which are involved in
brain, leading to mental disorders or diseases. Sexual addiction, although not always recognized, is a severe condition which affects many. Sexual addiction should be widely acknowledged as a severe issue because of its impact on the addict's nervous system, the root of its development, and its relevance to human behavior. What is sex addiction? The term "sexual addiction" is used to explain the behavior of a person who has an unusually intense sex drive or an obsession with sex. Those suffering
Most recognizable symptoms can usually be attributed to other causes; however, further analysis may lead to mitochondrial mutations being the definitive cause, especially these symptoms within the following systems. Mitochondrial diseases of the central nervous system or the peripheral nervous system usually show the stereotypical childhood symptoms, such as “developmental delay or regression, seizures, and movement disorders.” In adult-onset mitochondrial disease, symptoms would instead involve stroke
in Chapter 1.1 Overview of Anatomy and Physiology, it is “the state of steady internal conditions maintained by living things.” It also serves as the process that maintains and regulates our natural functioning, in other words. The importance of homeostasis in the body is to make sure that each internal role is functioning correctly. Throughout this paper, we will discuss how homeostasis affects the skeletal system. To understand homeostasis and its effects on the skeletal system, we must first learn
(8) There are even some cases of MS being diagnosed in childhood. Multiple sclerosis is a disease that affects the central nervous system, attacking the brain and the spinal cord. MS attacks myelin, the fatty material that acts as a protective coating to the body's nerves. (1) The inflammation of the nerve tissues covering the nerves can affect any part of the nervous system and varies from person to person. (7) Normal nerve function decreases with the onset of MS because MS causes scars to form
different severities of this disease, but without treatment it can not only affect the entire nervous system but eventually shut down the rest of the body. The myelin sheath is a fatty substance that surrounds the axons of the nerves and provides protection. It allows messages to be sent rapidly and accurately to the axons from long distances (Serono, 2010). The axons are the part of the nervous system that allows electrical transmission of signals throughout the brain and spinal cord. Without these
Herpesviral encephalitis Herpesviral encephalitis is encephalitis due to herpes simplex virus. Herpes simplex encephalitis is a viral infection of the human central nervous system. It is estimated to affect at least 1 in 500,000 individuals per century and some studies suggest an incidence rate of 5.9 cases per 100,000 live births. The majority of cases of herpes encephalitis are caused by herpes simplex virus-1, the same virus that causes cold sores. 57% of American adults are infected with HSV-1
