Part 1 Option B Explain how neurons transmit information. ‘Our knowledge of the neurons function helps us to understand human behaviour.’ Discuss. The relationship between biology and psychology is a ‘give-and-take’, shared relationship where one can be used to explain and provide insight into the other, as both are related to the physical body and the mind. For that reason biology holds a much significant and important role in the study of psychology. One of the main areas of psychological studies is the mind therefore this essay aims to explain the biology of how neurons transmit information, this essay also aims to discuss how our knowledge of the ways neurons functions helps us to understand human behaviour. Biology has a†¦show more content†¦Therefore if the receptors on a postsynaptic neuron do not match the neurotransmitter then this can cause inhibition. Example of psychological disorder that inhibition can cause is schizophrenia, an illness caused by abnormality of certain neurotransmitter found in parts of the brain. Many psychological disorders and aspects of our psychological lives are partly caused by manipulation at the synapses. And therefore have their biological basis and links to the brain. Emotions, motives, moods, cognition and behaviour are all caused when the activity in the neural system is changed or due to malfunction of synapses. For example Parkinson disease is caused by disruption in neurotransmitters. Drugs such as Prozac are used to cure depression, depression which is caused due to change in the brain either in malfunction of the neurotransmitters or the synapse. Sometimes malfunction is caused when neurons reuptake neurotransmitters that have already been released (Toates.2007, p.259) Neurons also play a part in the control of our behaviour. Like when our brain gives signals to the rest of the body to move via neurons. To move our legs, our legs need a large supply of blood therefore the brain needs to send messages to the heart also. Two parts of the nervous system operate to carry out such movement, the semantic nervous system and the autonomic nervous system. The semantic nervous system controls the skeletal muscles, thus is

Environmental Contaminants And Its Effects On Children

Parents of newborns have a million things on their minds when it comes to taking care of and protecting their babies. Feeding them, making sure they don’t fall, and trying to keep them from getting sick are just a few of the many overwhelming outside influences that could affect a babies wellbeing. Unfortunately, for many parents, there are several dangerous substances that could have a detrimental effect on a newborn’s health. These pathogens hide in our homes, water sources and our air. Infants are consistently bombarded with environmental contaminants and the ramifications on their health can be serious and lifelong. Unless parents have been educated about these risks, moms and dads often have no idea their babies are constantly in contact with these poisonous toxins. As soon as babies are born, they are immediately exposed to thousands of contaminants in their environment (Rogge, Combs-Orme). Environmental contaminants are found everywhere in our surroundings and scientists know that children are far more vulnerable to their damaging effects. Their sensitive, developing bodies are more likely to hold chemical concentrations in their tissues and cells because of their smaller size (Rogge, Combs-Orme). Most environmental contaminants are can be classified into three categories: microbiological, chemical or radiation (Karr). Certain contaminants cause immediate, acute illness and in the most severe cases have been linked to infant mortality and SIDS (Rogge,Show MoreRelatedWater Quality and Contamination1230 Words   |  5 PagesJacqueline Poole 10/6/2013 Week 5 – Water Quality and Contamination Final Lab Abstract Testing of how ground water is affected by different contaminants was the bases of the experiment.

The Great Gatsby by F. Scott Fitzgerald Free Essays

For my book report, I chose to read The Great Gatsby by F. Scott Fitzgerald. It is a novel set in the twenties when the American economy was soaring (SparkNotes†¦). We will write a custom essay sample on The Great Gatsby by F. Scott Fitzgerald or any similar topic only for you Order Now I choose this book because I had it in my bookshelf for a long time, but never found time to read it. I had no expectations of this book because I had never heard anything about it, and the summary on the back was un-descriptive. In this paper I will accurately and specifically go into the characters of the book, and present the themes, motifs and symbols of The Great Gatsby.The Great Gatsby has five important characters, all which play very different and crucial roles to the story. Tom, Daisy, Jordan and Gatsby are the characters who are rich, indulgent and selfish (Homework†¦). Nick is the narrator as well as the only one who leaves a modest live, and seems to have a moral compass. I found the characters in The Great Gatsby exaggerated and unrealistic. The group of rich people had great drive, but all had no conscience or morals. Nick is the most morally sound of the group, seemingly because his lack of riches (The Great Gatsby). The main character of the book is also the inspiration of the title, Jay Gatsby (SparkNotes†¦). He is a complicated character and we get to know him at many different stages of his life. We meet him as extravagantly rich and successful Gatsby, (Ross). He has the means to have extravagant parties every Saturdays, but he seems to be desperately searching for something. We learn about the history of Gatsby When learn that at one point he was called James Gatz (The Great Gatsby). He was poor and dreamed of the day he would have all the money he wanted. He fell in love with Daisy before leaving to fight in the war, but the pressure of parents and society were so great to marry someone in her ‘class’, she broke and married Tom. When Gatsby returned and realized Daisy had married, he was heartbroken. He worked for Dan Cody; a bootlegger involved with illegal things. Gatsby gets into the business and makes his fortune (NovelGuide. com). We learn that Gatsby has parties only because he knows that Daisy lives across the lake and hopes against odds that she will stumble into one and they will be reunited. We see that his moral code is also skewed when he has nothing against having an affair with Daisy. By the end of the story, we conclude that Gatsby is innocent dreamer who puts to much faith in people. He believes that Daisy is flawless, and all she does is disappoint him (SparkNotes†¦). His trust of Daisy and of unattainably dreams ultimate leads to his death (Homework†¦). The main theme of The Great Gatsby is the disintegration of the American dream in a time of major economic prosperity (SparkNotes†¦). Although the twenties were a time of wealth, parties, and pleasure; Fitzgerald is showing the moral corruptness of the culture as a whole. Another crucial theme in this book is class of peoples. Daisy marries Tom instead of Gatsby because of his position and wealth. She loves Gatsby, but she would rather have money and a good reputation (Homework†¦). Jordan and Nick try to have a relationship but it doesn’t work because their differences in class. Jordan follows in Daisy’s shoes and has a â€Å"shotgun† wedding to a rich man instead of Nick. There are two main motifs if this book. There are two peninsulas just outside New York which are crucial to this story, West Egg and East Egg. The East Egg is where the wealthy and â€Å"old aristocrats† live (SparkNote†¦). Daisy, Tom and Jordan live there. Nick and Gatsby live on West Egg; this is where the newly rich live. These are the showy rich who the East Egg people look down on. The geography of the country is also important. We know this by how the book highlights the differences between living out West and in the East. The East is grouped with New York and represents the moral decay of the wealthy while the West is seen as a more traditional and conservative which values morals and truth (SparkNotes†¦). We see two main symbols in this book. When Nick first sees Gatsby, he doesn’t introduce himself because Gatsby is staring intensely across his lake at a green light. We later learn that that light is on Daisy’s dock, and that Gatsby watches it to feel connected with her. This shows how he looks forward in his life, and believes in his dream. He has drive to get what he wants, without being afraid to work and strive for it (SparkNotes†¦). There is a billboard at a garage in the Valley of Ashes (the road between East and West Egg) that has giant spectacled eyes painted on. These are the eyes of Doctor T. J. Eckleburg, and are an ad for his practice. These eyes watch all the characters at different times and may represent the eyes of God (SparkNotes†¦). We see this because they make Tom uncomfortable when going to visit his mistress and because a man points to them saying, â€Å"God sees everything† (128). Although no one is ever punished, these eyes are the reminder of guilt for characters at different times (Homework†¦). There is no obvious spirituism to show a fear of, or lack of fear, in a god. Though not specially shown, the lack of morals shows the characters lack of trust in God. All wealthy characters have carelessness for others. When Nick tells Jordan she is an bad driver and should stay off the roads because she will hurt other drivers she says, â€Å"they’ll keep out of my way† (63). When Daisy hit Tom’s mistress with her car, she did not even attempt to go back and see the damage she did, just drove on like nothing happened. The rich can afford to run away from their problems– so they no longer have the necessity for god when they can solve all there problems. This paper accurately went into the characters of the book, and presented the themes, motifs and symbols of The Great Gatsby. I did not enjoy this book because the plot was slow and the storyline weak. This book was hard to identify with because it was in such a different time then I live. I didn`t enjoy this book and would not recommend it to anyone. How to cite The Great Gatsby by F. Scott Fitzgerald, Essay examples

Opinion on Afremovs Water Pastel Painting Essay Example For Students

Opinion on Afremovs Water Pastel Painting Essay First of all, I chose Leonie Foreman because admire the quality of his work. Before chose him as my subject, I did check out other artists like David Clerical who specializes in photography, portraits, landscapes film, There is Marcel Christ as well, whose torte is still elite and also dabbles in personal work and film, Benedict Regard on the other hand, does a little of everything such as photography, landscapes, epic set-ups and still life. I had to really think hard on Sam Logan because her line of art is my weakness. She is a stylist thereby her expertise is in clothing designs, set designs, and also experiments on still life. L almost picked her but Foremost work moved me more because it communicated admire artists so much since dont think have one artistic bone in to me. My body however hard try. I am in awe of people who looks at a picture, picks up a pencil then just starts drawing with such ease and confidence. Foreman paints With such emotion and inspiration that everyone can relate to it. His use of nature, surroundings and the combination of colors is so unpredictable that t surprises his viewers. Melody Of the Night depicts that the cover Of darkness when night falls doesnt mean that the exciting day is over. It shows that it only has begun but now in a different setting at a different time. It makes one realize that dusk can be breathtakingly beautiful when an explosion of contrasting colors are used to create an unforgettable heartwarming scene. I believe that what makes Foremost work very effective is that it isnt difficult to grasp. Any individual can relate to his work and appreciate its beauty due to its simplicity. It likewise sends a message that even darkness can bring about a lively scene with the correct use of colors and various painting techniques. The technique I liked most that Foreman utilized a lot in this painting is stippling. He used it to texture botanical drawings that created the appearance to depth. He did in such a way that it made the whole painting look elegant and life-like, Composition was another technique Foreman used that impressed me. It made the painting look put together and organized. Melody of the Night contains line, shape, arm, space, texture, value and color. He manipulated these elements and created something quite amazing. The effectiveness of Foremost work depends on the individual whys viewing it since everyone has their own opinion and interpretation of any kind of art. I personally, am very impressed with this particular painting because see that the techniques he used were quite effective. How does one measure the effectiveness Of an artwork to an individ ual who doesnt know much about art? I measure it on how affects my senses usually emotionally. It would be great if can touch and feel its texture and composition to give me an idea of the depth of the painting, however that isnt possible in this case. Using my sense Of sight tells me that he put his own feelings into this painting because it exudes his personal touch and his attention to detail. He took advantage of the darkness to bring out an explosion of hues and colors that one wouldnt expect. He brought light and life to a scene that could very well be ordinary or even boring.
