I chose this article from the Science Daily for my anatomy and physiology in the news assignment due to its mention of anatomical terms neurons, cortex and thalamus. This article entitled “Decision making involves a little known brain region in the thalamus” was developed by scientist from the Institute de Neurosciences Cognitives et Intégratives d'Aquitaine . The decision making process was thought to usually involve the orbitofrontal cortex. This article discusses the new discover that the thalamus also plays an important role in these decisions. I will be discussing the cerebral cortex, thalamus and neurons.
“Neurons are the basic information processing structures in the central nervous system”(Anatomy and Physiology, the unit of Form and Function,7th edition, Saladin). The function of a neuron is to receive information from other neurons, process that information, then to send information to other neurons. The neurons are connected by synapses which are what help the information flow from one neuron to another tissue. The three main parts of a neuron are the axon, the dendrites, and the soma also known as cell body. The axon carries information away from the soma and transmits it to other neurons. The dendrites receive information from other neurons. The soma contains the nucleus of the cell and protein synthesis occurs here.
A bundle of axons is also known as a tract. Tracts carry signals from one central nervous system level to another. There are six tracts in the spinal that are ascending, and seven that are descending. Ascending tracts are known as sensory, and descending are motor tracts. One of the ascending tracts is the spinothalamic tracts. This tract carries signals for pain, temperature, pressure, tickle, itch and light touch. The fibers in this tract lead all the way to the thalamus, the neurons continue form there to the cerebral cortex. The…...

...Chapter 6 The political situations in both China and Russia before their revolutions were much the same. Both had weak rulers and discontented people. In China, a succession of dynasties had ruled since ancient times. At the beginning of 1909, the Chinese emperor Kuang-Hsu had recently died. He left behind three-year-old nephew PuYi to rule the throne with the baby's father, Prince Chun, as regent. Kuang-Hsu's aunt had great power over the rule of her nephew, and she prevented him from taking measures toward the modernizing that China badly needed. China needed a strong, modern monarch to rule and not a three-year-old. Mother Russia had also hosted an absolute monarchy for centuries. By the 1900's, Nicholas II ruled all of Russia's vast territory. His father, Alexander III, ruled strictly but ended up stirring the kettle of discontent before passing the throne to his son. Nicholas ruled about one hundred years too late. Part of the problem was that he came after a series of rulers also in the wrong time. By the time he inherited the throne, there was little hope for Russia's monarchy. Nicholas II further destroyed that hope through extensive war and political entanglements with religious leaders of the Russian Orthodox Church. He participated in several wars despite the fact that his country could not really handle it. This destroyed the trust the masses of peasants and workers had in him, in the church he controlled, and in the government as a whole. Similarly, in...

P&G Case Study

...Summary Statement/Abstract P&G is a global company that is involved in many different markets including beauty and grooming and household care. The company has been through a lot of change due to the O2005 project that was undertaken in 1999 and saw a complete overhaul of the company during those years. One product that also was involved a lot during that time was the SK-II skin care product which was popular in Japan and a man named de Cesare wanted to take the product global to either the Chinese or European market. However, in order to do this there was a lot of analysis and research which had to be done to determine which market was the best to move the product to and de Cesare had to make a recommendation to the GLT knowing that he must do everything possible to make sure he made the best decision possible. As Paolo DeCesare, what factors do you need to consider before deciding what to recommend in your SK-II presentation to the global leadership team (GLT)? What kind of analysis will you need to do in preparing for that meeting? As Paolo DeCesare there are a lot of factors to consider before deciding what to recommend in the SK-II presentation to the GLT. The biggest factor of course to consider is the profitability of the market or markets that would be chosen to enter in an effort to have SK-II become a global brand within P&G. In order to determine this there is a lot of analysis that goes into determining whether a market will be profitable and could...

... the TIMES in a phone conversation: 'If our government knows anything about these devices, the people should be told at once. A lot of people out here are very much disturbed. Some think these things may be from another planet... Arnold, in pointing to the possibility of these discs being from another world, said, regardless of their origin, they apparently were traveling to some reachable destination. Whoever controlled them, he said, obviously wasn’t trying to hurt anyone. …He said discs were making turns so abruptly in rounding peaks that it would have been impossible for human pilots inside survived the pressure. So, he too thinks they are controlled from elsewhere, regardless of whether it’s from Mars, Venus, or our own planet." Arnold expressed similar views in a 1950 interview with journalist Edward R. Murrow: "...if it's not made by our science or our Army Air Forces, I am inclined to believe it's of an extraterrestrial origin." Arnold had first brought up the subject on June 27, 1947, when he described an encounter he had with a near-hysterical woman in Pendleton, Oregon, shrieking, "there's the man who saw the men from Mars." Arnold then added, "This whole thing has gotten out of hand... Half the people I see look at me as a combination Einstein, Flash Gordon and screwball." When the 1947 flying saucer wave hit the U.S., there was much speculation in the newspapers about what they might be in news stories, columns, editorials, and letters to the editor. Like...

...“Better a diamond with a flaw than a pebble without.” Confucius. Society has all sorts or rules, norms, and values. However, we don’t all necessarily share these common. Ideally, laws embody rules made by society to protect the weak and enforce a common standard. They represent a binding contract between citizens. When we imagine a world where everyone does just what they want, chaos and anarchy remains; at which point none of us would know where we stand when we do things. Fortunately, society has long established and continues to reinforce the importance of rules and structure. In effect, laws make us all responsible to society and its betterment. Everything about daily life is affected by law, whether we like it or not. Laws, good or bad, are essential to society; our “communities”, as we know them, would cease to exist outside this fact. Nevertheless, since humans are not perfect, “human laws”, whatever its source or intended impact/ remedy, are intrinsically flawed. History is consistent with this fact. Laws set “appropriate behaviors”, but “appropriate” is subjective to conditions, time, power, and/ or struggles. While we don’t want to live without laws and, God forbid, become animals, there are laws that should be changed. History proves how laws can often unfairly discriminate against particular groups of people based on race, gender, and/ or sexual orientation. The theory of law is far from the reality of its application. There has been gross misconduct...

...Revision question p 460 1. Casual attribution is a method in which to attribute what caused success or failure in a certain situation. There are four categories which are Ability, Luck, task difficulty and effort. These four categories can be split into 2 sub-groups Internal/ external and stable/unstable. 2. Attribution theory looks at the reason for why someone failure or succeeded in a certain situation. This is important from a sports psychologists view because models such a Wieners give people the ability to blame their failure on external reasons out of there control and therefore keep motivation high. 3. The locus of causality dimension indicates whether the attribution relates to factors that are either internal or external to the performer. Effort and ability represent internal factors while task difficulty and luck are external and are known as environmental variables. Stability indicates whether attributions are stable or unstable. Stability refers to the degree of permanence associated with an attribution factor. A stable factor is considered permanent and unchangeable, for example ability. An unstable factor, by contrast, is temporary and can be changed. Luck is an example of an unstable factor. Control, which will be considered later, is a third dimension of the attribution model. It is not referred to directly in the specification but is a key factor in the important process of attribution retraining. 4. If a hockey player continues to lose...

P&H Religion Essay

...Coen Ayres Religion in Pompeii and Herculaneum This response seeks to assess the following quote, “the study of Pompeii (P) and Herculaneum (H) provides us with a wealth of sources-however we are faced with issues regarding their limitations, reliability and usefulness”, in regard to four different levels of religion. Those four levels are household, foreign, local and state. In regard to the statement it can be agreed upon that the first half of the quote is true and that there are a wealth of sources, but the second half of the quote which states that there are issues of limitations, reliability and usefulness in these sources is only semi-true as it depends on the type of religion being discussed. Religion will be examined from the least problematic to the most problematic in regard to wealth of sources, reliability, limitations and usefulness; household religion, foreign religion, local religion and state religion. There is a wealth of sources regarding household religion in P and H and there are no issues regarding their reliability and limitations. One could relate this due to the fact that there has been evidence of most households practicing religion in their homes. The focus of household religion was the worship at a shrine called a lararium. These larariums were often depicted in an architectural style, such as the one found in the house of the Vettii (P) and the house of the Black Salon (H) which both resemble a temple in their style. The larariums could have...

...Brief Outline: Omnitel’s Marketing Director ”Bona” and CEO ”Caio” was planning to discuss about proposal for a new pricing strategy for Italy’s second mobile phone service provider. Omnitel conducted some marketing research and find that customers were very happy with Omnitel’s customer service. Italian customers do not wanted to pay fixed monthly usage fee and extra activation fee; instead they only wanted to pay a fee only when they used the phone. TIM (Telecom Italia Mobile) is the state owned company which had a complete monopoly over Italian telecommunications market. Bona was planning to launch his cell phone under the name “LIBERO” which is free from any monthly charges. LIBERO Plan: In Peak hours: Charge- Lit.1595 In Off-Peak hours: Charge- Lit.195 Anticipated average usage: 193 min per month Outgoing calls: 93 min (13 min at peak and 80 min at off-peak) Incoming calls: 100 min (25 min at peak and 75 min at off-peak) Setup Cost = Lit.10000 They are also providing customer a subsidy on handsets in exchange of a contract for a year or two. Bona was planning to convince Caio to sell cell phones at full price but drop the monthly fee. Bona wanted to launch a Advertising Campaign with a budget of Lit. 40 billion, because he wanted to completely blanket Italy with LIBERO posters and billboards so that he can change the customer mind-set regarding cellular phones.

On February 17, 1987, the appellant was terminated under hospital personnel policies following a “third corrective action” notice. Ms. Rodman was reprimanded in June of 1986 in light of receiving an inordinate number of personal calls and visitors at her work station. The formal reprimand set forth conditions to prevent further corrective action. The conditions were as follows: no personal telephone calls during work hours outside of a designated break or dinner time, these are to occur in an area not visible to patients, physicians, or other staff. When leaving for dinner, Rodman was to report to her immediate supervisor and was not to leave the hospital. According to the testimony given by Rodman’s supervisor disruptive telephone calls continued. In November of 1986 Ms. Rodman received another written reprimand stating that her job was in jeopardy. Ms. Rodman’s supervisor established restrictions prohibiting visitors at the department and instructed her to notify security if there was a potential problem. On February 15, 1987 Ms. Rodman began work a 1:00 p.m. Ms. Rodman had spoken to her boyfriends’ mother earlier informing her she did not wish her boyfriend to use her car and that she had broken off their relationship.
