Catecholamines and Cortisol Help to Fight Stress - 531 Words

When stress occurs, our bodies respond by releasing hormones that help our bodies deal with the stress. Catecholamines (epinephrine and norepinephrine) and cortisol are hormones that are major players in the stress response (McCance Huether, 2010). Catecholamines share some common physiologic actions with cortisol. Catecholamines and its metabolic actions are similar to those of cortisol. Both catecholamines and cortisol cause an increase in blood glucose through increased gluconeogenesis (McCance Huether, 2010). Gluconeogenesis is the production of glucose when the activation of certain enzymes occur (McCance Huether, 2010). Both epinephrine and cortisol also cause an increase in blood glucose by preventing cells in the body from the uptake of glucose and decreasing the effects of insulin (Judd, n.d.). Catecholamines and cortisol both cause an increase in cardiac output and an increase in blood pressure as well (McCance Huether, 2010). Catecholamines do this by enhancing myocardial contractility, increasing heart rate, and increasing the blood (venous) returning to the heart (McCance Huether, 2010). Cortisol aids in this effect by increasing the amount of receptors that epinephrine and norepinephrine can attach to ( Judd, n.d.). Cortisol and catecholamines both cause lipolysis is some areas of the body. This occurs in the extremities with cortisol, but most areas of the body with catecholamines (McCance Huether, 2010). Strangely enough, bothShow MoreRelatedThe Effects Of Hormones On The Body s Central Glucocorticoid1746 Words   |  7 PagesACTH acts on receptors of the adrenal cortex to stimulate the synthesis and release of cortisol [19,20]. Also known as the body’s ‘‘stress hormone’’, cortisol travels through the blood in both protein-bound (inactive) and free (active) forms. Cortisol can act to limit its own synthesis via a negative feedback mechanism to the hypothalamus and pituitary gland [19,20].

It can be found in the sun, the stars,comets, and the atmospheres of most planets. There are close to ten millionknown carbon compounds, many thousands of which are vital to the basis of lifeitself (WWW 1). Carbon occurs in many forms in nature. One of its purest forms is diamond. Diamond is the hardest substance known on earth. Although diamonds found innature are colorless and transparent, when combined with other elements itscolor can range from pastels to black. Diamond is a poor conductor of heat andelectricity. Until 1955 the only sources of diamond were found in deposits ofvolcanic origin. Since then scientists have found ways to make diamond fromgraphite and other synthetic materials. Diamonds of true gem quality are notmade in this way (Beggott 3-4). Graphite is another form of carbon. It occurs as a mineral in nature, but itcan be made artificially from amorphous carbon. One of the main uses forgraphite is for its lubricating qualities. Another is for the lead in pencils. Graphite is used as a heat resistant material and an electricity conductor. Itis also used in nuclear reactors as a lubricator (Kinoshita 119-127). Amorphous carbon is a deep black powder that occurs in nature as a component ofcoal. It may be obtained artificially from almost any organic substance byheating the substance to very high temperatures without air. Using this method,coke is produced from coal, and charcoal is produced from wood. Amorphouscarbon is the most reactive form of carbon. Because amorphous carbon burnseasily in air, it is used as a combustion fuel. The most important uses foramorphous carbon are as a filler for rubber and as a black pigment in paint (WWW2). There are two kinds of carbon compounds. The first is inorganic. Inorganiccompounds are binary compounds of carbon with metals or metal carbides. Theyhave properties ranging from reactive and saltlike; found in metals such assodium, magnesium, and aluminum, to an unreactive and metallic, such as titaniumand niobium (Beggott 4). Carbon compounds containing nonmetals are usually gases or liquids with lowboiling points. Carbon monoxide, a gas, is odorless, colorless, and tasteless. It forms during the incomplete combustion of carbon (Kinoshita 215-223). It ishighly toxic to animals because it inhibits the transport of oxygen in the bloodby hemoglobin (WWW 2). Carbon dioxide is a colorless, almost odorless gas thatis formed by the combustion of carbon. It is a product that results fromrespiration in most living organisms and is used by plants as a source of carbon. Frozen carbon dioxide, known as dry ice, is used as a refrigerant. Fluorocarbons, such as Freon, are used as refrigerants (Kinoshita 225-226). Organic compounds are those compounds that occur in nature. The simplestorganic compounds consist of only carbon and hydrogen, the hydrocarbons. Thestate of matter for organic compounds depends on how many carbons are containedin it. If a compound has up to four carbons it is a gas, if it has up to 20carbons it is a liquid, and if it has more than 20 carbons it is a solid(Kinoshita 230-237). The carbon cycle is the system of biological and chemical processes that makecarbon available to living things for use in tissue building and energy release(Kinoshita 242). All living cells are composed of proteins consisting of carbon,hydrogen, oxygen, and nitrogen in various combinations, and each living organismputs these elements together according to its own genetic code. To do this theorganism must have these available in special compounds built around carbon. .ucec752932d29500de5cb9227dc7998f5 , .ucec752932d29500de5cb9227dc7998f5 .postImageUrl , .ucec752932d29500de5cb9227dc7998f5 .centered-text-area { min-height: 80px; position: relative; } .ucec752932d29500de5cb9227dc7998f5 , .ucec752932d29500de5cb9227dc7998f5:hover , .ucec752932d29500de5cb9227dc7998f5:visited , .ucec752932d29500de5cb9227dc7998f5:active { border:0!important; } .ucec752932d29500de5cb9227dc7998f5 .clearfix:after { content: ""; display: table; clear: both; } .ucec752932d29500de5cb9227dc7998f5 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ucec752932d29500de5cb9227dc7998f5:active , .ucec752932d29500de5cb9227dc7998f5:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ucec752932d29500de5cb9227dc7998f5 .centered-text-area { width: 100%; position: relative ; } .ucec752932d29500de5cb9227dc7998f5 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ucec752932d29500de5cb9227dc7998f5 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ucec752932d29500de5cb9227dc7998f5 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ucec752932d29500de5cb9227dc7998f5:hover .ctaButton { background-color: #34495E!important; } .ucec752932d29500de5cb9227dc7998f5 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ucec752932d29500de5cb9227dc7998f5 .ucec752932d29500de5cb9227dc7998f5-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ucec752932d29500de5cb9227dc7998f5:after { content: ""; display: block; clear: both; } READ: Religion is Unnecessary EssayThese special compounds are produced only by plants, by the process ofphotosynthesis. Photosynthesis is a process in which chlorophyll traps and usesenergy from the sun in the form of light. Six molecules of carbon dioxidecombine with six molecules of water to form one molecule of glucose (sugar). The glucose molecule consists of six atoms of carbon, twelve of hydrogen, andsix of oxygen. Six oxygen molecules, consisting of two oxygen atoms each, arealso produced and are discharged into the atmosphere unless the plant needsenergy to live. In that case, the oxygen combines with the glucose immediately,releasing six molecules of carbon dioxide and six of water for each molecule ofglucose (Beggott 25-32). The carbon cycle is then completed as the plantobtains the energy that was stored by the glucose. The length of time requiredto complete the cycle varies. In plants without an immediate need for energy,the chemical processes continue in a variety of ways. By reducing the hydrogenand oxygen content of most of the sugar molecules by one water molecule andcombining them to form large molecules, plants produce substances such as starch,inulin , and fats and store them for future use. Regardless of whether thestored food is used later by the plant or consumed by some other organism, t hemolecules will ultimately be digested and oxidized, and carbon dioxide and waterwill be discharged. Other molecules of sugar undergo a series of chemicalchanges and are finally combined with nitrogen compounds to form proteinsubstances, which are then used to build tissues (WWW 2). Although protein substances may pass from organism to organism, eventuallythese too are oxidized and form carbon dioxide and water as cells wear out andare broken down, or as the organisms die. In either case, a new set oforganisms, ranging from fungi to the large scavengers, use the waste products ortissues for food, digesting and oxidizing the substances for energy release (WWW1). At various times in the Earths history, some plant and animal tissues havebeen protected by erosion and sedimentation from the natural agents ofdecomposition and converted into substances such as peat, lignite, petroleum,and coal. The carbon cycle, temporarily interrupted in this manner, iscompleted as fuels are burned, and carbon dioxide and water are again added tothe atmosphere for reuse by living things, and the solar energy stored byphotosynthesis ages ago is released (Kinoshita 273-275). Almost everything around us today has some connection with carbon or a carboncompound. Carbon is in every living organism. Without carbon life would notexist as we know it.

Speech on Dr. B.R. Ambedkar free essay sample

Ambedkar was born in the British-founded town and military cantonment of Mhow in the Central Provinces (now in Madhya Pradesh). He was the 14th and last child of Ramji Maloji Sakpal and Bhimabai. His family was of Marathi background from the town of Ambavade in the Ratnagiri district of modern-day Maharashtra. They belonged to the Hindu, Mahar caste, who were treated as untouchables and subjected to intense socio-economic discrimination. Belonging to the Kabir Panth, Ramji Sakpal encouraged his children to read the Hindu classics. He used his position in the army to lobby for his children to study at the government school, as they faced resistance owing to their caste. Although able to attend school, Ambedkar and other untouchable children were segregated and given no attention or assistance by the teachers. Ramji Sakpal retired in 1894 and the family moved to  Satara  two years later. Shortly after their move, Ambedkars mother died. We will write a custom essay sample on Speech on Dr. B.R. Ambedkar or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Of his brothers and sisters, only Ambedkar succeeded in passing his examinations and graduating to a higher school. Ambedkar remarried in 1898, and the family moved to Mumbai (then Bombay), where Ambedkar became the first untouchable student at the Government High School near Elphinstone Road. [7. In 1907, he passed his matriculation examination and entered the University of Bombay, becoming one of the first persons of untouchable origin to enter a college in India. This success provoked celebrations in his community, and after a public ceremony he was presented with a biography of the Buddha by his teacher Krishnaji Arjun Keluskar also known as Dada Keluskar, a Maratha caste scholar. Ambedkars marriage had been arranged the previous year as per Hindu custom, to Ramabai, a nine-year old girl from Dapoli. [7] In 1908, he entered Elphinstone College and obtained a scholarship of twenty five rupees a month from the Gayakwad ruler of Baroda, Sahyaji Rao III. By 1912, he obtained his degree in economics and political science from Bombay University, and prepared to take up employment with the Baroda state government. His wife gave birth to his first son, Yashwant, in the same year. Ambedkar had just moved his young family and started work, when he dashed back to Mumbai to see his ailing father, who died on February 2, 1913. In 1922 through unremitting hard work, Ambedkar once again overfulfilled all expectations:. While practicing law in the Bombay High Court he ran head long in to uplift the untouchable to educate them. . By 1927 Ambedkar decided to launch active movements against untouchability. Upon Indias independence on August 15, 1947, the new Congress-led government invited Ambedkar to serve as the nations first law minister, which he accepted. On August 29, Ambedkar was appointed Chairman of the Constitution Drafting Committee, charged by the Assembly to write free Indias new Constitution. Ambedkar won great praise from his colleagues and contemporary observers for his drafting work. Ambedkar studied Buddhism all his life, and around 1950s, he planned to make a formal conversion back to Buddhism and this work was done by a priest named Chintamani. He was bed-ridden owing to clinical depression and failing eyesight. [11]  . His health worsened as he furiously worked through 1955. Just three days after completing his final manuscript  The Buddha and His Dhamma, it is said that Ambedkar died in his sleep on December 6, 1956 at his home in Delhi. On the anniversary of his birth (14 April) and death (6 December) and on Dhamma Chakra Pravartan Din, 14th Oct at Nagpur, at least half a million people gather to pay homage to him at his memorial in Mumbai. Thousands of bookshops are set up, and books are sold. His message to his followers was Educate!!! , Agitate!!! , Organize!!! .
