  • Aids - 1,140 words
    ... rom a few days to several weeks and is associated with fever, sweats, exhaustion, loss of appetite, nausea, headaches, soar throat, diarrhea, swollen glands, and a rash on the torso. Some of the symptoms of the acute illness may result from HIV-1 invasion of the central nervous system. In some cases the clinical findings have correlated with the presence of HIV-1 in the cerebrospinal fluid. Symptoms disappear along with the rash and other sings of acute viral disease. When the blood test for HIV-1 antibodies become available, researchers demonstrated the lymphadenopathy was a frequent consequence of infection with the virus. Scientist do not know what causes the wasting syndrome, but som ...

  • Fetal Tissue Transplants - 1,664 words
    Fetal Tissue Transplants Is the transplantation of nueral tissue considered an ethical procedure? The transplantation of human fetal neural tissue into the brains of humans suffering from progressive neurodegenerative disorders is one of the hottest arguments currently being debated. Fetal neural tissue is being used as a possible treatment for some diseases. The treatment and possible cure for many of these diseases falls upon the successful transplantation of fetal neural tissue from the brain, spinal chord and peripheral nervous system. Some of the possible beneficiaries of these transplants would be those with Parkinson's disease, a common neurodegenerative disorder of the nervous system ...

  • Leopracy Decease - 224 words
    Leopracy (decease) title = Leopracy (decease) Leprosy is a chronic infectious disease that affects the skin and the mucous membranes, especially those in the nose and in the peripheral nervous system. Leprosy is not usually fatal, however, patients with untreated infections may develop crippled hands and or feet. Leprosy results from infection by a rod-shaped bacterium called mycobacterium leprae, sometimes known as hansens bacillus. Leprosy infections occurs primarily in human beings, armadillos, chimpanzees and Mangabey monkeys. Researchers do not know how the bacteria is transmitted. Evidence show it is caused by inhaling the bacteria or from skin to skin contact. Leprosy resist infection ...

  • Nerve Regeneration - 1,136 words
    Nerve Regeneration Topic: New ways to aid in nerve regeneration. General Purpose: To inform Specific Purpose: To inform the audience about news techniques and mechanisms that aid in nerve regeneration. Central Idea Statement: The new techniques for nerve regeneration involving magnetic, electrical, and chemical mechanisms look very promising. INTRODUCTION I. The site is rather common: someone in a wheel chair unable to use their lower body, or worse, unable to function from their neck down because of an accident. You may even know one of these people. They all have one thing in common: spinal nerve injury. To the majority of us, one of the more famous and recent cases involving spinal trauma ...

  • Nervous System - 430 words
    Nervous System The Nervous system The nervous system can be separated into three divisions, the central nervous system, the peripheral nervous system, and the autonomic nervous system. The Central Nervous system consists of the brain and the spinal cord. The spinal cord is a long, thick nerve trunk that rus from the base of the brain down through the spinal column, or backbone. The cord is composed of white matter. A cross sectional view of the spinal cord shows the gray matter as an H shaped area surrounded by white matter. Thirty one pair of spinal nerves leave the spinal cord. Each of these nerve trunks is attacked to the cord in two places. The root of the nerve that leaves the cord towa ...

  • Reflexology - 2,156 words
    Reflexology The origins of Reflexology evidently reach back to ancient Egypt as evidenced by inscriptions found in the physicians tomb at Saqqara in Egypt. The translation of the hieroglyphics are as follows: Dont hurt me. The practitioners reply:- I shall act so you praise me. We cannot determine the exact relationship between the ancient art as practiced by the early Egyptians and Reflexology as we know it today. Different forms of working the feet to effect health have been used all over the ancient world. Dr. Riley maintained that this form of healing spread from Egypt via the Roman Empire. The Zone Theory was the precursor to modern Reflexology which began with Dr. William H. Fitzgerald ...

  • Ritalin - 1,449 words
    Ritalin Ritalin The Babysitter of the 90's 07/03/2000 Prepared for Nursing 2116 by Tracey Hardin Ritalin (Methylphenidate) is a mild CNS stimulant. In medicine, Ritalin's primary use is treatment of Attention Deficit /Hyperactive Disorder (ADHD). The mode of action in humans is not completely understood, but Ritalin presumably activates the arousal system of the brain stem and the cortex to produce its stimulant effect. Recently, the frequency of diagnosis for ADHD has increased dramatically. More children and an increasing number of adults are being diagnosed with ADHD. According to the Drug Enforcement Agency (DEA) (Bailey 1995), prescriptions for Ritalin have increased more than 600% in t ...

  • Spinal Cord Injuries - 1,283 words
    Spinal Cord Injuries As an Emergency Medical Technician (EMT), when someone has a spinal injury, additional movement may cause further damage to the spine. EMTs must always immobilize the patients head and torso in the position found. The purpose of an EMT is to prevent further harm to the patient until more professional medical help can be obtained. If in doubt about whether a person has received a spinal injury, always assume he or she has. A spinal cord injury (SCI) is very serious because it can mean the loss of sensation and function in the parts of the body below the site of the injury. SCIs are caused in many different ways. Some of the most common ways a person may obtain a SCI are- ...

  • Spinal Cord Repair - 667 words
    Spinal Cord Repair Spinal Cord Repair Once a pipe dream, researchers now are uncovering ways to repair spinal cord injuries. Current methods reduce the nerve cell damage or death that occurs in the hours following injury and increase the efficiency of surviving nerve cells. New evidence suggests that future treatments also may assist the regeneration of lost connections. Prospects include transplanting new nerve cells and supporting cells, delivering proteins that stimulate regeneration by the cells already in the spinal cord, and strategies to reduce inhibition of regeneration.

  • The Nervous System - 1,981 words
    The Nervous System The nervous system is the most complex part of the body, as they govern our thoughts, feelings, and bodily functions. It is an important factor in science because it can lead to new discoveries for cures or diseases. The studies of the nervous system helped lower death rates from heart disease, stroke, accidents, etc. The nervous system is a network of neurons (nerve cells) that that sends information to the brain to be analyzed. Neurons live both in and outside the central nervous system. Understanding how the neurons work is vital to understanding the nervous system. Neurons The neuron has two important structures called the dendrite and axon, also called nerve fibers. T ...
