Adrenaline Essay Example for Free

Adrenaline Essay Most of us, at some point, have been excited or thrilled as a form of entertainment. Whether it is a roller coaster at an amusement park or a scary movie, some results from this form of exciting entertainment may include tense muscles, increase in heart rate, increase in blood pressure, or excessive perspiration. Such physical effects are caused by Adrenaline. Adrenaline is a hormone that is released from a person’s adrenal medulla during emergency situations but does not have psychoactive effects. It is released into the person’s body from the adrenal glands located above the kidney. It is commonly referred to as a â€Å"fight-or-flight† hormone, because of its effects in increasing the supply of glucose and oxygen directed at a person’s brain and involuntary muscles. This allows the person to have better physical abilities to utilise during an emergency. Adrenaline is also known as epinephrine. Adrenaline is derived from the Latin roots ad, meaning towards and renes, meaning kidneys. Epinephrine originated from the Greek roots epi, meaning on, and nephros, meaning kidneys. This is in reference to the physical location of the adrenal glands in a person’s body, atop the kidneys. Norepinephrine or noradrenaline is another hormone released from the adrenal glands. It is very closely, chemically related to adrenaline, as well as having similar effects on the human body. However, a significant difference between the two hormones is that adrenaline has no psychoactive effects, while noradrenaline does, affecting the person’s mental processes. The effects of adrenaline released with into the bloodstream include the stimulation of involuntary muscles, rising blood pressure, conversion of glycogen, a form of stored body fuel, inside the liver into glucose, heart rate increase, the dilation of the bronchioles, the fine, thin-walled, tubular extensions of the bronchus, in the lungs, increased breathing rate, increased metabolic rate, and decreased digestive and kidney activity. The release of adrenaline into a person’s blood stream can be seen as the changing of a gear in a manual car. The release of adrenaline allows a person’s body to be able to have better physical performance in the event of an emergency, while the changing of a gear in a manual car allows the car to have better performance and be able to reach higher speeds than at the lower gear. The diagram included shows the cross-sectioned view of adrenal gland. It identifies both the outer layer, known as the cortex, and the inner area, known as the medulla. The adrenaline is secreted from the inner area. Below it, the location of the adrenal gland is shown in relation to the kidney inside a human body. As indicated, it is located above the kidney. In terms of my art practice, my adrenaline is often released while I am working. For example, while completely three-dimensional projects in the workshops, the power tools and other machines make me very nervous while using them. As a result, my adrenal glands release adrenaline, making my heart rate increase exponentially. In other cases, inspiration for art may also cause the release of adrenaline in my both. Similarly, when I use great emotion into my paintings. I am also excited to the point of adrenaline release.

Environmental Effects of Fossil Fuels Essay -- Essays Papers

Environmental Effects of Fossil Fuels Besides food, fossil fuels are our most important resource. According to www.bydesign.com, there are three major resources. These resources are coal, oil and natural gas. The environmental impact of fossil fuel usage affects us greatly as individuals and as a global community. Coal causes much damage to our environment. Coal extraction is a serious cause of water pollution. Coal is used primarily to produce electricity. Coal releases nitrous oxide when it is burned. Nitrous oxide unfortunately stays in the atmosphere for a long time. Because this is kept in the atmosphere for such a long time it is very difficult to see or predict the harmful effects of this gas. Nearly fifty percent of the nitrogen oxide in the atmosphere is directly produced by coal. According to www.eia.gov the US energy supply and demand predicts that annual coal usage will increase from 1146 million short tons to 1175 million short tons. This means that the environmental detriments from coal usage will only increase. Currently, there is no sure way to relieve the environmental stressors caused by coal. However, for me, personally, this is a relief. This is relieving because my father owns a small family business that sells mulch and driveway stone. During the winter months, his busine ss depends on coal sales. In the past few decades, household usage of coal has decreased significantly due to the growing availability and convenience of other fuels. I do not believe that this statistic indicates that the average for household usage will increase, but it is encouraging to hear that coal will not disappear anytime soon. Oil is another one of the fossil fuels to which many of my father’s previous customers are conv... ...vironment. Overall, fossil fuels have major impact on our environment. Our energy choices leave lasting impacts on the lives of plants, animals and ourselves. Many health and physical concerns can be linked to fossil fuel usage. Hopefully, by reducing our energy consumption we will be able to protect our lives and lives of those to come.

The Exploitative Colony of Virginia Essay - 4348 Words

The Exploitative Colony of Virginia I believe that the early settlers of the colony of Virginia made it into an exploitative and ignorant colony, due to the fact that it was set up primarily to make a small number of individuals wealthy while ignoring the rights of its other members. In the year 1607, a group of adventurers from the Virginia Company established the first English-American colony in the Chesapeake Bay area (Greene, 1988). They landed in Jamestown, and it became the first English settlement to survive in the New World. They named the colony Virginia. In its early history, Virginia was known for its drive to conquer the land and in some cases people, so that it would bring its main benefactors wealth and power†¦show more content†¦The relationship was shaky mainly because the Europeans were naive and ignorant to the Native Americans way of life. Thus, twice the Indians put on all out attacks against the unsuspecting Europeans because of this fact. Through it all, the early history of colonial Virg inia suggest that it was backwards compared with other colonies, but Virginia eventually began to settle down and found its way to stability after it spent most of its history being ignorant to the red, black, and even in some of the white men. In 1588, the defeat of the Spanish armada by Englands Sir Francis Drake signaled the slow decline of Spain. But while this was happening the first permanent settlement of the English in the New World on Reannex Island fails. It was then almost two decades later till they tried again (Todd Curti, 1968). However, Spain was different from the English, in that what their explorers did was under government supervision; it was all done in the name of Spain. England was not a wealthy nation, so they could not finance groups like Spain had done. However, they did promise land to those who were willing to adventure out to the New World. Trade companies then took it upon themselves to finance and establish land out-posts in the New World. Therefore, the control of the New World would be that of those from the Old World.
