Ever wonder why you get goose bumps? Do they serve a purpose? Why do they develop when we are cold? Cutis anserine is one of the medical terms for Goosebumps (cutis means skin and anserine means goose). The term describes a change in the skin from smooth to bumpy which usually occurs after exposure to the cold. Most animals regulate their body temperature at a particular level. For humans it is 37°C. If the temperature is too high the body will apply different mechanisms to decrease its temperature. E.g. sweating and dilation of blood vessels. If the temperature is to low the body will counteract to increase the temperature. E.g. shivering, constriction of blood vessels and goose bumps. This is a negative feedback system which allows us to maintain homeostasis. Homeostasis is the process of keeping a constant internal condition.

How do we keep things the same? To keep our body at a constant temperature we need three things: receptors, a processing centre and effectors. Thermoreceptors in the skin detect changes in external temperature. They pass this information on to the processing centre in the brain called the hypothalamus which is a tiny gland in the brain. An important job of the hypothalamus is to regulate body temperature.

Your body’s reaction to heat loss is involuntary and controlled by the hypothalamus. When it receives the message from the thermoreceptors it automatically triggers changes to effectors.

The effectors are tiny muscles called arrector pili found attached to the hair follicles. When stimulated, these muscles will contract and cause the...

...bag, and went outside. The stone filled yard was cracking under my white new shoes. At my way down the street, I received a new message; should I go without you? I choose to ignore it. I was only a few blocks away from him anyway. Just a moment after I got another one saying; Closet. I did not understand that one. Was this supposed to be some kind of bad joke? I arrived at John’s house about 7:30am. When the message copied itself. Closet. I did not know the number it came from. John helped me looking it up. However, no one owned that number. There was not even an IP-Address showed. The cold word was teasing me. John told me to ignore it, that it possibly only was some random 10 year old messing around with me. When we arrived at the school, it seemed to be a quite normal day. However, something did not feel right. Like that feeling, you get when someone is watching you all the time. I felt stalked. The goosebumps was slowly starting to catch up. We walked down the hallway. I was not paying attention to what John was saying. Nevertheless, his lips was moving. The crowd around me slowly started to kick in my nerves. All the voices. I was hearing it everywhere! Closet. It repeated itself in every conversation. I began to walk faster. John tried to keep up. I somehow outran him. I am all alone now… I did not know what to do. Therefore, I collapsed at the ground. Desperately trying to take my phone out of my...

Rental Heart Essay We live in a world were hatred, war and racism has dominated for years. And we keep asking ourselves, why? Why do we still need love? Why can’t we live without it, and sometimes can’t live with it? What does it mean for us, when our hearts tell us to fell something for other humans? Its questions we keep asking ourselves because we don’t know how to handle love, how to control it, how to balance between our bad and good emotions and in the end we don’t know what real love is, before getting heart, maybe a few times. Love, emotions, a broken heart that never ends feeling empty, it’s basically what the story is about in the novel “the Rental Heart”. The short story presents a protagonist as neuter story teller. We don’t really know anything about this person, which sex the teller has, looks, anything from the outside besides the tellers thoughts and the chronological story that tells about the various attempts at love. The narrator introduces us to many different types of persons “she” had a relationship with. but that isn’t the focus we have in the novel, it is really about the questions we have on the persons’ sex’. The narrator keeps switching sex on “her” lovers, and sometimes we wonder if “she” switches “her” own sex. for example the narrators switching personality in the short story; “her pierced little mouth, her shitkicker boots, her hands as small as goosebumps writing numbers on my palm”.(page 1 line 1-2) The narrator is the one who gives most attention to the......

...Homeostasis Homeostasis is a process of where our body has to be able to control certain things such as body temperature and the water level so that they don’t change, therefore it is when it keeps things the same. It is how the body keeps the conditions inside, and some scientists refer to it as a constant internal environment; two examples of this is: • Keeping the body temperature at 37 degrees, • The amount of water in our body. Our bodies are always making adjustments to be able to carry out normal bodily functions, but fortunately for us the adjustments are done automatically, if this wasn’t the case then we would all be very busy and would regulate our internal environment very frequently. Homeostasis is controlled by the Automatic nervous system and the Endocrine system (hormones). Negative feedback system Homeostasis is quite often referred to as the negative feedback, which means that the system is able to take suitable action to maintain the constant environment. The main responsibility of homeostasis is that it has to maintain constant levels of many body functions e.g. body temperature, heart rate, breathing rate, and also blood sugar levels. Body temperature The term used for monitoring the body temperature is called thermoregulation. An adult’s body temperature is usually close to 37 degrees. There are temperature detectors in the skin and the internal organs monitor it and feedback to the hypothalamus in the brain to take the correct action when the......

...Product Reassessment: The Traditional Printed Books Decline Wendy Anderson Strayer University Principles of Marketing August 7, 2013 The Traditional Printed books Decline The decline of the traditional printed book has become more noticeable since book stores have either closed some locations or closed their doors all together. There are still many people in the United States that know the value of owning and reading the traditional printed book. However, in current times convenience and laziness has become the standard. There are a lot of people that would prefer to carry around light weight technology such as an e-reader that can house a multitude and array of books than carry around a 500 page book or a multitude of said books. The use of e-readers to access e-books has become the wave of the future and the norm in today’s world. However, there are still many avid readers within the population that enjoy the feel and the read of the printed book. It is believed that everyone should have the opportunity to witness the advantages of reading the traditional book and be able to enjoy the experiences that a traditional book can bring to the table. As said before there a lot of people that still enjoy holding a printed book, turning the pages of said books and enjoy reading their genre of reading in the old fashioned way.

Final Essay’ll notice about this assignment is that elements of it are modeled off of previous assignments. This is deliberate, as they’ve given you practice at this type of argumentation. This special topic section of English Composition II has focused upon the horror genre as practiced by American writers. We’ve read and discussed several works from horror authors over the course of the nation’s history, and considered in-depth longer fiction from the 20th Century horror icon Shirley Jackson. We’ve also delved into popular culture, examining comic books and, time permitting, television shows and movies. For this essay, you’ll be asked to pick another horror story (see The Topic section for some ideas) to add to this course’s discussion. In the interest of time, I suggest a short story, but you could read a novel for this project as well. More specifically, your essay should do the following things: (1) Provide your readers unfamiliar with your chosen text some context about the work, including a brief summary of the story. Likely, this would occur in your first support paragraph after your introduction. (2) Review the story. This is your opportunity to argue whether or not the text makes for a “good read.” You may turn to the elements of fiction that we’ve worked on this semester as a way of detailing why you feel the way you do about the book. You might also turn to any reviews or analysis of the tale or its subgenre that you’ve uncovered in your research – and incorporate......

...of DH Lawrence there is the common theme of the relationships between men and women. In these three stories we explore the uncertainties of romantic love. All of the characters discover that they have not seen the other as they truly are but rather as an idealized and impossible halucination. In Elizabeth's case in Odour of Chrysanthemums she realizes the truth of her relationship with her husband Walt when she is faced with his death. The cold room magnifies the feeling of their distance, and when she compares Walt's mothers response to her own she knows she has not loved him or ever really seen him. Hilda reveals to Syson that he never could accept her how she truly is, that he could never love her if he really saw her, and this is why she broke things off with him. Hilda shows off the antique chair she has found, and Syson is suprised that she would like something like this. He begins to notice Hilda may not be the person he thinks he knows. She shows him the scissors that she found hidden in the chair, and has him try them on.

...result, he garnered a good deal of criticism from the literary world. But, it is precisely because he was such an individual and his voice so original that Frost became so beloved. Born in San Francisco, Frost moved to Massachusetts at age eleven following his father’s death. He attended both Dartmouth College and Harvard University, but never earned a college degree. He was, however, often invited to teach at Dartmouth and Harvard later on in his life. You know you’re good when you get to teach college students without having a diploma yourself. After spending some time in England, Frost befriended a lot of poetic giants, including William Butler Yeats and Ezra Pound. Frost won four Pulitzer Prizes in his lifetime, and he was asked to read a poem atPresident John F. Kennedy’s inauguration. If you are to randomly choose one of Frost’s poems and read it aloud on a busy street, we bet that a bunch of people will recognize the poem instantly as Frost’s – his sound and style is so unique.   Why Should I Care?

I feel like I matured so much from my freshman year until now. I learned a lot from Moeller and I feel like they teach you more than academics they teach you about life.
