The Ear and Hearing Loss The ear is the organ of hearing and balance in vertebrates. The ear converts sound waves in the air, to nerve impulses which are sent to the brain, where the brain interprets them as sounds instead of vibrations. The innermost part of the ear maintains equilibrium or balance. The vestibular apparatus contains semicircular canals which in turn balance you. Any movement by the head, and this apparatus sends a signal to the brain so that your reflex action is to move your f
Heart Attacks Heart attacks are the leading cause of death in the United States. Everyday approximately 1,500 people die from heart attacks. Thousands more suffer crippling effects of some form, and remain disabled for the rest of their lives. A simple definition of a heart attack is a sudden failure of the heart resulting from an occlusion or obstruction of a coronary artery. Basically, this means the heart is no longer receiving the blood supply it needs to function properly. A person having a
Hemispheres of the Brain As I was reading the text I came upon a section that I thought to be quite fascinating. It talked about people who have a brain that functions like two different people inside of the brain. This is of course the Split-Brain Personality. As I studied this topic in more detail I found it to be quite broad and yet very detailed. I found that I needed a dictionary to be able to read all of the medical journals and books that are out there, to be able to understand what it wa
Hemophilia Tim Poisal Biology-2nd period Hemophilia is a genetic blood disease, which is characterized by the inability of blood to clot, or coagulate even from minor injuries. This disease is caused by an insufficiency of certain blood proteins, called factors, that participate in blood clotting and often by sudden gene mutation. Therefore, with the absence of factors, the blood clotting process is prolonged. There are different types of hemophilia, hemophilia A and hemophilia B for example. He
Hepatitis In modern society when a person gets sick with the flu or a cold they will usually go about their normal routine with the exception of a sneeze or a cough throughout the day. Sometimes things can be more than what they appear to be. The symptoms start out like the flu with coughing, fever, aches, and vomiting. However, the disease gradually worsens with symptoms of extreme weakness and excrushatating abdominal pain. By then it is usually too late when the person finds out that their li
AIDS - Acquired Immune Deficiency Syndrome Timur Eren Spring 96 HPE12 BACKGROUND Since the first AIDS cases were reported in 1981, through mid-1994 more than 402,000 AIDS cases and more than 241,000 deaths have been reported in the United States alone. This is only the tip of the iceberg of HIV infection, however. It is estimated that nearly 1 million Americans had been infected with the virus through the mid-1990s but had not yet developed clinical symptoms. In addition, although the vast majo
HIV Like the majority of the American population I have lived in a cloud of ignorance about the HIV and AIDS crisis. I have never know anyone close to me that has been infected with either of the two viruses. So when the option to research something to do with sexuality arouse I felt this would definitely further my education about a lethal killer that is roaming this earth. Since I knew next to nothing about this topic I will start from the begging of the disease and discuss where it\'s at now.
Hospice General Purpose of the Department: As we have learned, the hospice idea is not new. Literally meaning "given to hospitality," hospices provided comfort, kindness, and nourishment to people in need hundreds of years ago. Today, hospices offer comfort to people as they near the end of life\'s journey. Hospice is a special way of caring for people with terminal illnesses and their families. It is a multidisciplinary health care program that is responsible for palliative and supportive care
How has AIDS affected our Society? Today more Americans are infected with STD\'s than at any other time in history. The most serious of these diseases is AIDS. Since the first cases were identified in the United States in 1981, AIDS has touched the lives of millions of American families. This deadly disease is unlike any other in modern history. Changes in social behavior can be directly linked to AIDS. Its overall effect on society has been dramatic. It is unknown whether AIDS and HIV existed a
Huntington\'s Disease Huntington\'s Disease is a rare hereditary disorder. It is characterized by irregular movements of the body, slurred speech, and the deterioration of mental functioning. Symptoms of the individual include alternating periods of excitement and depression. It is caused by a buildup of neurotransmitter fluids, which can cause schizophrenia. The first symptoms of the disease usually appear between the ages of 35 and 45, but much earlier and later occurrences are also known. Sin
Huntington\'s Disease Huntington\'s disease, or Huntngton\'s chorea, is a genetic disease that causes selective neural cell death, which results in chorea, or irregular, jerking movements of the limbs caused by involuntary muscle contractions, and dementia. It can cause a lack of concentration and depression. It also may cause atrophy of the caudate nucleus, a part of the brain. However, symptoms vary between individuals, with some sufferers showing symptoms that others do not. Those suffering f
Huntington\'s Disease Background Huntington\'s disease is inherited as an autosomal dominant disease that gives rise to progressive, elective (localized) neural cell death associated with choleric movements (uncontrollable movements of the arms, legs, and face) and dementia. It is one of the more common inherited brain disorders. About 25,000 Americans have it and another 60,000 or so will carry the defective gene and will develop the disorder as they age. Physical deterioration occurs over a pe
Hypnosis The British Medical Association and the American Medical Association has called it "a temporary condition of altered attention in the subject that may be induced by another person," (Compton\'s Multimedia Encyclopedia) but there is still much about hypnosis that is not understood. Because it resembles normal sleep, it was studied and was found that the brain waves of hypnotized people are more similar to the patterns of deep relaxation than anything else. Rather than a psychic or mystic
Hypnosis in Psychology Throughout the history of this country, hypnosis has been dismissed as a form of gimmickry. Contrary to this, for centuries numerous cultures have used hypnosis as a means of mental and spiritual healing. Hypnosis is defined as an induced trance-like state in which one is highly susceptible to suggestions, or commands. There are three commonly known methods of hypnosis. Two of which, the authoritarian and standardized approaches, are generally considered non-beneficial tow
Observational Abilities Test INTRODUCTION What is true in the eyes of one, can be seen as a delusion in another. We, as a society, are made up of a dramatically diverse amalgam of cultures and abilities. Finding out what those differences are can help us reach a better understanding of each other, thus a more equitable relationship can be developed. Therefore, finding the observational abilities of a given group may help yield some interesting and valuable information. In the following study sev
Lord of The Flies: Human Nature "We are all murderers and prostitutes - no matter to what culture, society, class, nation one belongs, no matter how normal, moral, or mature, one takes oneself to be." R. D. Laing British psychiatrist. R.D. Laing obviously backs up William Golding\'s point of view that human nature is evil. Human nature is directly affected by the environment; and is constantly changing due to the experiences of the individual. Oscar Wilde once said "The only thing that one reall
Salt and Its Uses As we know, salt is the most useful resource found on earth. In Ancient Rome, salt was used as part of the salary to the soldiers. From this, we can see that salt was as valuable as gold in the past. In our daily life, besides making nutritious food more palatable, salt is very useful in making bakery products, canned and frozen foods. Salt is a good preservative that retards the growth of micro-organisms to make food storage possible for a long period of timie before refrigera
Lancelot and Odysseus "Let love be without hypocrisy. Abhor what is evil; cling to what is good (Romans 12:9)." This principal seems to be markedly evident as one closely examines the actions and thoughts behind the character of Sir Lancelot in The Knight of the Cart. When one encounters the adventures of Odysseus in The Odyssey, however, the values of a completely different and slightly opposing culture present themselves. In the medieval times of Sir Lancelot, an ideal man would tend to follow
The Effects of Lead Poison on Children Throughout the world today one out of every six children under the age of six are suffering from health disorders due to a poisonous metal known as lead(Kiwanis, 1996). Lead is a natural occurring bluish-grey metal found in the earth\'s crust. It has no taste or smell. Lead can easily be found in all parts of our environment today. Most of it comes from mining, manufacturing, and last but not least the burning of fossil fuels(Xintaras, 1993). In the United
Leukemia Leukemia is a cancer that has had a significant effect on our society and with the developments of new drugs it may become treatable. Leukemia originates in the blood-forming organs which may include the lymph tissue and bone cells. In a person with leukemia the rate and the number of cells produced is altered. This altering can become fatal, or with proper treatment it can be subdued. There are two main types of leukemia which include "total" and "differential." These are mainly charac
Today\'s Society Is A Dangerous and Corrupt Place Today\'s society is a dangerous and corrupt place. People would lie , cheat , and steal just to make a dollar. People are even taking there parents to court these days . How ludicrous can a person get ? A person would sue a tobacco company because they had developed cancer . This is outrageous ! For one reason , how could a person just pick on one company in particular . Because of the fact that a person could not smoke just one brand of cigarett
Euthanasia and Living Wills THE STORY Imagine someone you love...better yet, imagine yourself lying in a hospital bed oblivious to the world around you, unable to move or show any signs of life, your own existence controlled by an I.V., a respiratory machine, and a feeding tube. In essence you are dead. Your body is no longer able to sustain life, its entire purpose is now replaced by a machine - you are being kept alive by artificial means. At this point the question arises - should you be kept
Lucid Dreams: The First Virtual Reality Psychological Sean Pasinsky LibEd 316-2 5 Feb. 1997 For ages people have thought of dreams as curses or blessings that we could not prevent nor manipulate. This "place" called our dreams has constantly puzzled us, because it is here where all things are possible and seem to occur. In our dreams we perform superhuman and wonderful feats that would normally be impossible in the "awake world". We find the men or women of our dreams, depending on our sexual or
Make-Up Art Cosmetics Make-up Art Cosmetics, also known as M.A.C. cosmetics is a highly unique corporation. Its founders and business strategies are rather simple yet extremely effective in contributing to the companies success. The company does not use any fancy business schemes and it is truly concerned with its consumers. In the beginning, the company struggled to get started, but now a multimillion dollar (and still growing) enterprise, M.A.C. probably has some of the most popular and most d
Bovine Spongiform Encephalopathy Bovine spongiform encephalopathy (BSE) is a relatively new disease found primarily in cattle. This disease of the bovine breed was first seen in the United Kingdom in November 1986 by histopathological examination of affected brains (Kimberlin, 1993) . From the first discovery in 1986 to 1990 this disease developed into a large-scale epidemic in most of the United Kingdom, with very serious economic consequences (Moore, 1996). BSE primarily occurs in adult cattle
Mandatory AIDS Testing AIDS has become a worldwide epidemic that has struck every identifiable group. However, persons who are considered to be in a high-risk group of contracting HIV, the disease believed to cause AIDS, are still stigmatized by the media and other professionals as being diseased and abnormal. It is quite surprising still that this type of stereotype still exists now in our gender-bending society. No longer do only gays, prostitutes, bisexual men, intravenous drug users contract
Medical Miracles on the Horizon The world and its inhabitants will face a multitude of problems in the 21st Century, including drug addiction, deadly disease, violent crime, warfare and hostility, hunger, and homelessness to name a few. All of these critical issues have been present to some extent in the 20th Century and, left unsolved, will continue to plague society and mankind as we enter the new millennium. As we rapidly approach the next era, new issues of equal or even greater importance f
About Medical Marijuana Marijuana is medicine. It has been used for thousands of years to treat a wide variety of ailments. Marijuana (Cannabis sativa L.) was legal in the United States for all purposes - industrial and recreational, as well as medicinal until 1937. Today, only eight Americans are legally allowed to use marijuana as medicine. NORML is working to restore marijuana\'s availability as medicine. Medicinal Value Marijuana, in its natural form, is one of the safest therapeutically act
Marijuana As A Medicine If your every waking moment was consumed by pain and nausea, wouldn\'t you ask for medication? What if the only medication legally available would leave you unconscious or do nothing at all? If you were the one suffering, would you resort to the only treatment that allowed you to live normally even though it was illegal? Thousands of people across the country are forced to break the law to ease their pain. They have chosen marijuana over anything legally available because
Garlic I am doing this project because I think it would be interesting to figure out different things about medicinal plants and, I decided to try to focus on garlic because, for reason it is a medicinal plant and there is a range of reasons why garlic is important to us but there are things we need to be aware of though. For about 5000 years garlic has been known to reduce blood cholestrol levels. Garlic tastes very hot, dry, and pungent. The cloves (a part of the garlic plant) are used mostly
Minerals Minerals are required to build soft and hard body tissue. Without then we wouldn\'t exist. They also help out with the nervous system the contraction of mussels and help the blood flow properly. Minerals are classified into 2 major groups. The major elements such as calcium, magnesium, iron, iodine etc. Then the trace elements such as copper, manganese fluorine and zinc. Once of the most important is calcium. Calcium is used to build up your bones. It also helps to keep your teeth stron
Multiple Sclerosis Jason Garoutte November 18, 1996 English / Mr. Blunt Multiple sclerosis is one of the most misunderstood diseases of this century. Since it\'s discovery, there is still no known causes, no proven treatments, and no known cure, yet it affects possibly five hundred thousand people in the United States alone. People need to learn more about this disease so it can be brought to the attention of the nation. Multiple Sclerosis is a disease of the central nervous system. It destroys
Mumps Mumps is a disease caused by a virus and occurs only in human beings. Mumps is found all over the world. Mumps is a contagious disease when the salivary glands, on one or both sides of the jaw, swells. Mumps usually occurs in school age children, but young adults may catch the disease. Everyone born before1957 has already had mumps. After one attack of mumps, you will have lifelong immunity. The mumps virus is spread by contact of another person\'s discharge from the nose or mouth. The vir
Music and Stress During the first week of my self change project I monitored my stress levels and the way music effected the mental and physical aspects of stress. From monitoring this properly, I found that listening to music pleasing to me at the specifically different times I experienced stress did help reduce my internal feelings and physical changes. In carefully studying the various types of stress experienced I concluded that certain types of music more effectively reduced my stress and a
Narcissism: Psychological Theories and Therapeutic Interventions in the Narcissistic Disorders Introduction Understanding the Narcissistic Phenomenon The so called "narcissistic personality disorder" is a complex and often misunderstood disorder. The cardinal feature of the narcissistic personality is the grandiose sense of self importance, but paradoxically underneath this grandiosity the narcissist suffers from a chronically fragile low self esteem. The grandiosity of the narcissist, however,
What Are Visual Defects and How Common Are They ? by Nate Schackow 2nd Period December 17, 1996 The human eye does alot more than allowing you to see. It is very complex and has many parts and features which can have defects. However, to understand defects you must first know how the eye works. First light passes through the cornea, which is the transparent part of the sclera, or white of the eye, which is composed of tough fiberous tissue. Behind the sclera is a watery fluid called the aqueous

Nutrition and You Nutrition is the relationship of foods to the health of the human body . Proper nutrition means that you are receiving enough foods and supplements for the body to function at optimal capacity. It is important to remember that no single nutrient or activity can maintain optimal health and well being, although it has been proven that some nutrients are more important than others. All of the nutrients are necessary in different amounts along with exercise to maintain proper healt
Obesity America has become a society obsessed with appearance, especially weight. We are conditioned at a young age to believe the only way to be normal is to be thin. This norm is projected to millions of Americans each day through television, magazines, billboards and every other form of media and advertising. How are people to know acceptance and happiness with themselves and others when our culture propagates what the perfect body should be. It is the search for the elusive, perfect body tha
Observation of the Early Childhood An observation was held in the children\'"s wing of Tarrant County Junior College. A variety of children between the ages of two to six were observed in activities ranging from physical and motor to social and cognitive development. Specifically I mean that whether it was leadership skills or lack of, running, climbing and jumping, drawing and writing, or anything that could fall between, it has been seen, done and accounted for in the following observation.

Obsessive-Compulsive Behaviors "Compulsive" and "obsessive" have become everyday words. "I\'m compulsive" is how some people describe their need for neatness, punctuality, and shoes lined up in the closets. "He\'s so compulsive is shorthand for calling someone uptight, controlling, and not much fun. "She\'s obsessed with him" is a way of saying your friend is hopelessly lovesick. That is not how these words are used to describe Obsessive-Compulsive Disorder or OCD, a strange and fascinating sick
Osteoporosis Osteoporosis is a significant health problem that affects more than 25 million women in the United States and potentially 200 million worldwide. This disease is characterized by diminishing the structure of the skeleton (particular the "spongy" bone). This results in an increased risk of fracture. Osteoporosis develops silently over a period of years, eventually progressing to a point where a fracture can easily occur causing pain and disability. This disease is characterized by low
Our World In Medicine One of the most important factors about people\'s lives is the information of, the use of, and the growing knowledge of medicine. Medicine is a science that nations all over the world use. It is a science because it is based on knowledge gained through careful study and experimentation. Medicine is also an art form because it depends on how skillfully doctors and other medical workers apply their knowledge when dealing with patients.1 Medicine is one of the most respected p
Parental Pressure within High School Students I. I became interested in this topic because my entire academic life has been filled with pressure from my parents. This pressure was mainly in school and grades, and in high school, the amount of pressure increased dramatically. This is because my parents now realized that everything in high school counts towards college. When I first came to high school, my grades were not as good as they were in middle school. I needed a little time to adapt to hi
The Dawn of a New Age: PCP April, 1956 : The pharmaceutical company Parke & Davis first synthesize what they believe to be the perfect anesthetic (Souza, 1995). When administered to patients, it causes a completely dissociative state, with no significant respiratory or cardiovascular depression. Patients appear to be awake, eyes open, breathing normally.but are unaware of their surroundings or the procedures being performed upon them (Souza, 1995). Indeed, this is the perfect drug.

Pornography: Sex or Subordination? In the late Seventies, America became shocked and outraged by the rape, mutilation, and murder of over a dozen young, beautiful girls. The man who committed these murders, Ted Bundy, was later apprehended and executed. During his detention in various penitentiaries, he was mentally probed and prodded by psychologist and psychoanalysts hoping to discover the root of his violent actions and sexual frustrations. Many theories arose in attempts to explain the motiv

The Trials of Toilet Training Toilet training is difficult for both parent and child. Based on the research of two psychologists, Nathan Azrin and Richard Foxx, the average child can be fully trained in less than four hours. They began their training with mentally handicapped adults and successfully taught 95% in three days. With the added emphasis on language and verbal rehearsal they attempted to teach children and were astounded at the results. Their methods eliminate the fear damaging the ch
Premature Infancy Premature babies, otherwise known as preterm babies, or preemies, are babies that are born earlier than the full-term of thirty-eight to forty-two weeks of pregnancy. These babies are generally born between the twentieth and thirty-eighth week. Almost 250,000 babies, nearly seven percent of newborns, are premature(Golant 4). Prematurity, even with all the advances in technology, is still a major cause of fetal and neonatal death. Actually, around seventy- five percent of perina
