Central Nervous System Research Paper

1.1. Identify 2 conditions that may lead to an acute illness of the neurological system.

Neuroimaging can be a useful tool in detecting physical abnormalities in the brain. Most people with a severe brain injury will show an abnormality in a neuro-imaging test. These scans cannot detect all types of brain injuries, so it is possible to have a severe brain injury and be in a coma even though the scan results are normal.

There are three different theories that are used when talking about how we react to stress through the physiological aspect or the psychological aspect. The first is part of the physiological aspect of stress called the Cannon Fight or Flight theory which was proposed in 1914. Fight or Flight response is a physiological stress response that evolved to help organisms to survive immediate danger. The theory states that when an organism, human being or animal, faces imminent danger (acute stressor) the body arouses quickly and is ready to act via two different systems. They are the sympathetic nervous system and the endocrine system. The sympathetic nervous system stimulates the adrenal medulla which is part of the endocrine system and is the region that produces the hormones such as adrenaline and noradrenaline. These hormones increase heart rate, blood flow, and glucose levels to prepare the body for an emergency. This response from the body suggests that the body knows how to protect itself and reach homeostasis. These two systems work together to either fight against the danger or flight away from the danger. Lord, King and Pfister in 1976 studied the Fight or Flight response in animals through a very unethical study. They administered chemicals on male hooded Wistar rats which inhibited the neurotransmitters from functioning normally. This made it very difficult for the rats to escape an electric shock. The results of the study suggest that the Flight or Fight response

The CNS is responsible for accepting information from the rest of the body through the peripheral nervous system, and responding by sending signals back out into the body. It is essential that the CNS work properly for one to function properly and sustain life. However, there are circumstances in which it is necessary for the CNS to be suppressed or excited for the wellbeing of a patient. The CNS is affected by anesthetics, anticonvulsants, antiemetics, antiparkinson agents, stimulants, muscle relaxants, narcotic analgesics, nonnarcotic analgesics, and sedatives. The following will detail some of the previously listed types of pharmaceuticals that are used to affect the central nervous

Central nervous system (CNS) is a system in our body that is responsible for integrating, processing and coordinating sensory data and motor commands. It consists of the brain and spinal cord. CNS may be associated with a lot of disorder. An article written by Tim Newman in Medical News Today proclaimed that the major causes of disorders that effect the CNS are trauma, infections, degeneration, structural defects, tumors, autoimmune disorders and stroke. One of the most common disorder or disease related closely to CNS is multiple sclerosis. An article in the Medline Plus updated by Joseph V. Campellone, MD, Division of Neurology,at the Cooper University Hospital, Camden, NJ and Multiple Sclerosis society of Canada agreed that multiple sclerosis

First, our nerves respond by detemining a situation and deciding if it is stressful. This decision is made based on sensory input. By processing the things we see and hear and in stored memories. Also, what happened the last time we were in a similar situation. If the situation is judged as being stressful, the hypothalamus is activated. The hypothalamus in the brain is in charge of the stress response. When a stress response is triggered, it sends signals to two other structures: the pituitary gland, and the adrenal medulla. These short term responses are produced by The Fight or Flight Response via the Sympathomedullary Pathway.(SAM) Long term stress is regulated by the Hypothalamic Pituitary-Adrenal (HPA) system. This is what happens: The

Central nervous system (CNS) is composed of brain and the spinal cord. Neurons constitute a major part of the developing CNS. An axon is an extension of a neuron. The brain grows as a swelling at the front (rostal) end of the neural tube and later leads to become a spinal cord (1,2). Development of the CNS involves many complex mechanisms beginning at the onset of transformation of a single layer of ectodermal cells, the neuroectoderm until the end of the differentiation process resulting into highly complex structure involving variety of neural cell types (1,2). A large number of cell types need to be arranged spatially and temporally to form a complex structure during an

-The CNS is composed of the brain and the spinal cord. This system is responsible for the sensory information and responding accordingly. The spinal cord sends signals between the brain and the rest of the body and controls simple musculoskeletal reflexes. This isn’t using input from the brain. The brain is responsible for most sensory information and coordinating body function, both consciously and unconsciously. Also one portion of the CNS we may forget at times is the retina. The retina is formed as an out pocketing of the diencephalon during development. This is known as the optic vesicle.

Neurologists are licensed doctors who specialize in neurological disorders such as stroke, dementia and neuromuscular diseases. Neurologists examine patients and do diagnostic tests in order to determine the best way for treatment. They might also participate in clinical studies and other research, give presentations at meetings, and write articles for medical

What is the nervous ssystem? Thecentral nervous system consists of two things and that consist of the brain and the spinal cord. This is referred to as the "central". It combines different information from our entire bbody This coordinates the activities across the whole organism of our body. The most complex organ that we have in our body mainly uses up to 20 percent of our oxygen that is in and out of our systems every day. It comes to our brain this consist of an estimated 100 billion neurons but they are connected to a thousand more from there. When it comes to the brain it is divided into four main lobes that consist of parietal, frontal, occipital, and temporal lobes. This comes to the brain this skeleton protects your cranial cavity

Neurological assessment collect data on the patient's neurological status can be used for many reasons, including to help with diagnosis, as a benchmark perception, following a traumatic injury and neurosurgical technique. The five noteworthy sections of the neurological assessment are identified with the real areas of the central nervous system. The assessment is a progression of subtests grouped into five noteworthy segments. The first of these is the mental health status which evaluates the status level of consciousness and higher cognitive function for example, memory, language and orientation. At the second state, there is the cranial nerve assessment, which tests the function of the 12 cranial nerve and, in this way, the peripheral and

The central nervous system is composed of our spinal cord and brain which consistently controls our mind and behavior. The complexity of our brain is not entirely deciphered, but with extensive scientific research it can be concluded that each specific section has its own specialized function. In reference to eating pizza, socializing, and playing a game of cards, it can be deduced that our central nervous system is always critically analyzing data using our Broca’s area for speech, hippocampus for memories, hypothalamus controlling internal body, and occipital lobe organizing visual stimuli.

Central Nervous System: the brain and spinal cord together form the central nervous system, or

Broken heart, splintered mind and depressed soul. On sensing danger the Sympathetic nervous system triggers Fight or Flight response. The parasympathetic nervous system facilitates activities when our bodies are at rest including sexual arousal and appetite. The “survival” system is always prepared to respond to stressors in the environment and it is up to the “rest” system to halt this activity, much like a brake in a car.

Neurological assessment is a vital part of my physical examination of my patients. A neurological evaluation contains several exams, tests and procedures which are used to make the diagnosis of nervous system diseases. As mentioned by Jarvis (2012), some patients’ who are hospitalized might have neurologic deficit or trauma and require close monitoring. Obtaining information of the patient’s baseline of neurological function is a vital priority of my assessment. Change of mental status is subtle and an earliest sign of neurologic deficit (Jarvis, 2012). Accurate documentation and thorough assessment of the neurologic system is vital aspect of nursing care of all patients, most especially for the neurosurgical patient.
