Fight and Flight Flu and Alzheimer Disease Research Paper (Essay Sample) Content: FIGHT AND FLIGHT, FLU AND ALZHEIMER DISEASEName:Institution affiliation:Department:Date:Hungry bear body reactionIn cases of extreme fear and unimaginable queer scenarios like attending a barbeque and all of a sudden we get to notice some movements or rustling of nearby bushes and then at a glance we experience a charging mightily and huge ferocious hungry looking bear .This enormous mammal has smelled our finger licking picnic and wants some of the big share for himself. Its such a furious and strong enormous creature that can commission our lives just with a single swipe with its mighty powerful forearms. Imagining of this ordeal what pops up into ones minds is am in big trouble and want to save my life. The immediate thoughts will right be annexed to immediate need to get away from this ferocious animal.This immediate response or effect of thoughts is what is termed as physiological response that critically and suddenly prepares the body with fats and incredible sp eed, fight or strength, fight and flight.  This sudden response involves many complex interactions between organs and various systems in the body. A specific part of the nervous system known as autonomic nervous system will react quickly and responsively to the induce or trigger mechanisms beyond our control. The sympathetic nerve is particularly responsible for initiating fight and flight response at the sight of this ominous animal. This prepares the body to handle danger and pain (Rice, 1992)Consequently, the hypothalamus commonly called the master gland receives an impulse of impending danger and immediately triggers the adrenal gland releasing the adrenaline and cortisol hormone which prepares the body for fight and flight by servicing the cells with more speed and power in the case of being chased with a hungry bear (Karren, Hafen, Smith Frandsen, 2002).Other immediate physiological changes that result from activation of the autonomic nervous system include: Increased hear t rate, increased mental activity and central nervous system, increased muscle contraction as well as increased metabolism.The skin becomes cool and pale, this arises as result of withdrawal of much blood flow to the surface of the body which is greatly reduced and the supply is directed to the legs, arms, shoulders, eyes, brains and the nose. Besides the uncontrollable ability to run and fight the body prepares to think as fast as possible preparing for increased sensitivity to hear, see and smell things in better design than normally. This pulls blood away from the skin which also helps to reduce the bleeding in case of scrapes and cuts.Also to the eyes, there is increased supply of blood that has been redirected from the skin. This makes the veins and capillaries to have constant and more supply of blood thus making the pupils become more dilated so as to let more light in and consequently improving of sight sense.Also the upper and lower limb muscles and the skeletal muscles pre pares themselves to be injured and spends more energy in the larger muscle groups such as legs and arms as well as shoulders. This comes as a result of diverted supply of blood from the other parts such as the skin so as to accord it with the energy they require for the strenuous muscle contraction and relaxation (Kabat-Zinn, 1990).Finally, the respiratory system undergoes many complex interactions with the heart and other coordination with the circulatory system. The heart beat increases suddenly, blood is pumped quickly and vigorously to the muscles, eyes and ears. The rate of breathing increases too due to high oxygen demand to breakdown the lactic acid accumulated in the muscles as a result of fatigue.FLUCommonly called influenza, it is caused by the RNA virus that infects the respiratory tract of many mammals, birds and even man. The effects of flu on the respiratory tract include the congestion where someone feels to breath with the mouth open as the canals leading to the nose are blocked momentarily due to the contraction of the muscles inside the nose. Coughing arises as a result of this congestion and then one feels dehydrated and takes lots of water to counter this condition. Chest problem, discomfort, and cough might can be severe. Additionally, the nose becomes runny or stuffy with consequent muscle aches and the lack of appetite emerges as a result of sores in the throat which entirely diminish the urge to eat ("Flu, man flu or cold?", 2015)The skin also becomes pale with goose pimples developing as a result of fever. The sudden increased and declining temperatures are the sole cause of this goose condition. The veins dilate and constrict at times when fever upsurges and goes down. This is brought about by the registration of a signal to the liver and the hypothalamus which dilates and constricts this blood veins under the skin. This fever lasts for 3-5 daysThe part of the nervous system highly affected as the release of the cytokines and systemic symptoms such as headache and fever gets their trigger signal from the hypothalamus which is also controlled by the brain. As the cytokines activate the receptors in the brain they induce headache and trip pain in muscles accounting for the higher sensation of the nonspecific muscle soreness and pain ("Flu, man flu or cold?", 2015)Alzheimer diseaseYes, Jack is an Alzheimers patient. Despite the fact that hes able to live by himself most of the time, the symptoms that Jack presents forth which includes forgetting where he place his car key as well as his next doctors appointment qualifies and justifies the whole condition of being Alzheimer. Supporting this approval, most of the patients suffering from this disease are aged from 65 years and above .This disease its well documented that is the most common cause of dementia which involves progressive and constant degenera...

Essay Topics For The Rest Of UsAcademic freedom is a controversial topic that is often confused with free speech. In order to understand the two, you must be able to differentiate between these two issues.First, let's get things straight about academic freedom. Academic freedom does not give you the right to use someone else's words. It does not allow you to take ideas and run with them. The best that it allows you to do is put forth ideas and publish your work in a form that allows you to be critiqued. The best way to define academic freedom is that it protects your ideas.Many would argue that academic freedom is not as protected as free speech. After all, if you are to publish a study that points out the shortcomings of a certain group of people, you might as well say it was a hate crime. Or, if you are to point out that there are problems with the military and present that to Congress, you are showing disrespect to the military and the legislative branch. The point is that the edu cational process can sometimes be rough, and we can sometimes take the course a little too far.For this reason, academic freedom is especially important. It allows individuals to express themselves without fear of retribution from their peers. Instead, it gives them the freedom to develop their own personal ideas and move forward with them. This keeps them learning, creative, and inspired, not chained to a work on a subject they simply have no interest in.We have seen examples of this already on college campuses across the country. Over the past few years, the topic of political correctness has been raised in the political sphere. Universities have received letters from students complaining about how they are being treated by the media, politicians, and even fellow students. One such incident happened at Tufts University last fall. A group of students attempted to have a game change, so to speak, by bringing on the controversial play about gender wars, The Vagina Monologues.It was p ointed out that the play was created as a call for censorship, and in an attempt to curb free speech. But, Tufts officials felt the play was intended to be humorous and was not meant to be taken seriously. And since that time, other students have been able to voice their opinions about the situation without fear of reprisal.Of course, some will argue that free speech does not always have to be funny. However, this is a hypocritical argument. It was recently shown that it is okay to joke about politics, but not okay to joke about suicide. In fact, comedians like Jon Stewart and Stephen Colbert have been punished by networks for making jokes that are deemed inappropriate, yet they are able to continue to make jokes about issues and subjects that are not related to politics.Academic freedom is indeed important. We need to protect our ideas, not hold ourselves back because someone tells us that we are going too far. It's the only way we will be able to grow and learn.
