Cushing’s syndrome A healthy life is disturbed by a wide range of conditions, we refer to as diseases. Either chronic, malignt, mortal, genetic or even treatable; a disease is any abnormality in a human’s anatomy or physiology, based on a lexical point of view. According to Mayoclinic.com Cushing’s Syndrome is a chronic disorder in which the adrenal cortex produces excessive amounts of the hormone cortisol. It may also be induced iatrogenically by treatment with exogenous corticosteroids for other medical conditions. Cortisol is secreted by the adrenal glands under regulation by the pituitary gland and hypothalamus.
C. How are the chemical signals of insulin and glucagon received by the target cells? D. Explain the causes of diabetes mellitus type I and type II. (1) Answer A: Prolonged stress is conveyed to neurons in the hypothalamus of the brain. The hypothalamus produces a releasing hormone, which is secreted into the blood supply of the anterior pituitary gland. This causes the anterior pituitary gland to produce and secrete a hormone (adrenocorticotropic hormone) that travels through the circulatory system.
A. Nicotiamide adenine dinucleotide B. Flavin adenine dinucleotide C. Thiamin pyrophospate D. All of the above E. A and B 4. How does a riboflavin deficiency affect vitamin B6 metabolism? A. Riboflavin, as its coenzyme form flavin mononucleotide, is associated with an oxidase responsible for converting pyridoxine phosphate or pyridoxamine phosphate to pyridoxal phosphate. B. Riboflavin is the coenzyme form that is associated with an oxidase responsible for converting pyridoxine phosphate or pyridoxamine phosphate to pyridoxal phosphate. C. Dephosphorylation of the vitamin B6 vitamers during digestion requires flavin mononucleotide.
2. Explain how fosinopril works – include in your answer what physiological process the drug acts on and how it modifies this process. Normally in the body, the kidneys are able to assist in blood pressure regulation via the renin-angiotensin system, a system that regulates blood pressure and fluid balance. As blood pressure declines, renin enzymes are able to convert angiotensinogen into angiotensin I. Angiotensin-converting enzyme (ACE) then converts angiotensin I into angiotensin II, a powerful vasoconstrictor which also stimulates sodium reabsorption. As sodium ions attract water, water is also retained which increase blood volume and therefore blood pressure (Marieb & Hoehn, 2012).
Research Question: How does the adrenaline affect on the heartbeat of daphnia? Thesis: Adrenaline increases the daphnia's heart rate. The hormone circulates through the daphnia's blood and activates cell surface receptors in what is commonly called a pacemaker, or the sinoatrial node, which increases the rate of blood the heart ejects per minute. Noradrenaline, another hormone, and caffeine, a chemical, have the same effect. Apparatus and chemicals: Chemicals: Culture of water flea – Daphnia Chemicals that may affect the heart rate – at low concentrations( in that design that chemical would be adrenaline.
Lumbricalis variegates cardio vascular system has a myogenic nature(myogenic-depolarisation impulses for heartbeats originating in muscle cells), the dorsal and ventral blood vessels have peristaltic pumps (Halfmann & Crisp 2011). The chemicals chosen as the treatment is ethanol and nicotine, it is assumed that ethanol will slow the pulse rate in the cardio vascular system and that nicotine will speed it up, because of these stimulant and depressant nature. Materials & Method: * Blackworms Lumbricalis variegates (35) * Petri dishes (8) * Pipettes (8) * Paper towel * Recovery bowl * Microscope * Stopwatch * Slides
Estrogen You correctly answered: d. is produced by developing ovarian follicles. 3. Calcitonin You correctly answered: b. works against the development of osteoporosis. 4. Which of the following statements is true?
| | | | ephedrine (ephedra) | also known as ma huang, is an amphetamine-like drug called ephedra found in OTC herbal supplements. It is used in an array of products sold as weight-loss aids, asthma products, and energy boosters. Effects can cause blood vessel constriction and a sudden rise in blood pressure and body heat. | | | | fetal alcohol syndrome (FAS) | is a condition acquired by the fetus and is caused by the mother drinking alcohol during pregnancy. Alcohol irreversibly damages the developing brain.
In other words, chemically, what is going on inside the body of a PTSD patient? First, let us discuss the 5-HT transporter (5-HTT). Also known as the serotonin transporter, 5-HTT does exactly what you think it does: it transports serotonin from synaptic spaces into presynaptic neurons. The problem with 5-HTT is that if the promoter of 5-HTT is present, this can lead to an “increased sensitivity to stress and an increased incidence of depression and anxiety disorder” (Carlson 2011). In other words, one can become more vulnerable to stress-related disorders, like PTSD.
