...MESTRUATION / Female Anatomy maria PSY215 ALESSANDRO BIEN 03/02/16 Menstruation: The sloughing off of the built-up uterine lining that takes place if concepine lining that takes place if conception has not occurred. The menstrual cycle is the process of ovulation and menstruation in women and other female primates. It is regulated by intricate relationship between the hypothalamus and ovarious endocrine glands, including the pituitary gland, the adrenal glands, and the throughout the cycle, releasing chemicals that stimulate the pituitary to produce two hormones that affect the ovaries: follicle-stimulating hormone and luteingzing hormone. Our menstrual cycle phases occur each month when your reproductive system repeats a regular pattern of events, all controlled by hormones. There are four parts, or phases, that repeat. Here’s what you need to know about each: The menstrual phase is the part commonly referred to as “your period.” The official start of your cycle is the first day of your menstrual phase the first day of your period. You may be thinking, “Where is this stuff coming from?” Menstrual blood is shed from the lining of your uterus. It goes from your uterus through your cervix, vagina and out through your vaginal opening. A period usually lasts about three to seven days. It may seem like more, but the average amount of menstrual flow for your entire period is about a quarter of a cup. Ovulation is one part...

...Valerie Van Beusekom Pharm D IV Paper Proposal I. Title: Subclinical hypothyroidism. The importance of screening, treating and management of patients with slightly elevated TSH levels when compared to reference ranges. II. Problem: Purpose of the Study: Subclinical hypothyroidism is defined as an elevated serum TSH level with a normal serum free T4 concentration. Whereas hypothyroidism is an elevated serum TSH level along with a decreased serum T4 concentration. In subclinical hypothyroidism the TSH level is usually above 4.5 mIU/L but not greater than 10 mIU/L. Subclinical hypothyroidism is a common condition discovered by thyroid screening. According to the review of Helfand and Redfern, 5% to 10% of adult women have an elevated TSH level.5 Controversy persists about screening for subclinical hypothyroidism and the TSH level at which treatment should be initiated. A 1998 position paper from the American College of Physicians questioned whether there were sufficient data to recommend treatment of patients with subclinical hypothyroidism.6 A 2004 publication from the US Preventive Services Task Force found that the data were insufficient to recommend for or against screening in adults.7In 2002, a consensus development panel sponsored by the American Thyroid Association, the American Association of Clinical Endocrinologists, and the Endocrine Society found insufficient evidence to support screening and recommended against treating patients with a TSH concentration between...

The last part of the 19th century was a period of great achievements in medicine and endocrinology. The thyroid gland evolved from being considered a rudimentary structure to an organ related to specific diseases. The singular importance of iodine became acknowledged. Graves-Basedow’s disease was described. Surgical treatment evolved with extraordinary speed. Theodor Kocher observed that the clinical picture in patients after total thyroidectomy was similar to the one seen in cretinism. In 1850, the first case of hypothyroidism or myxedema was described. Less than 50 years later, effective treatment was introduced. Another 50 years later, autoimmune thyroiditis was ascertained as the most frequent cause of hypothyroidism (in areas with no iodine deficiency). This paper gives a short...

...immune system. Genetic makeup, prenatal experiences, and early life experiences are all different possible factors that can lead to different individuals to being more responsive to stress than others. Prolonged and repeated exposure to cortisol can increase susceptibility for certain illness and injuries amongst individuals. For instance, the rate of visits at a doctor’s office often increases amongst college students during finals week. Stress is part of life and it serves us in both positive and negative terms, however, in today’s fast paced work it’s doing more harm to our bodies than good. Our busy schedules with stress life situations are greatly impacting our stress levels and with repeated stimulation of the HPA (Hypothalamus, Pituitary Gland, and Adrenal Cortex) and exposure to cortisol, our bodies are taking the biggest...

...system. The endocrine glands are equally important parallel communication system in the body. The endocrine system is made up of glands that secrete chemicals directly into the bloodstream or the lymph system. I have found a table that shows which glands are in the body and what exactly they produce or do for a human. Adrenal glands - Divided into 2 regions; secrete hormones that influence the body's metabolism, blood chemicals, and body characteristics, as well as influence the part of the nervous system that is involved in the response and defense against stress. Hypothalamus - Activates and controls the part of the nervous system that controls involuntary body functions, the hormonal system, and many body functions, such as regulating sleep and stimulating appetite. Ovaries and testicles - Secrete hormones that influence female and male characteristics, respectively. Pancreas -Secretes a hormone (insulin) that controls the use of glucose by the body. Parathyroid glands - Secrete a hormone that maintains the calcium level in the blood. Pineal body - Involved with daily biological cycles. Helps regulate the body rhythms and sleep cycles. Pituitary gland - Produces a number of different hormones that influence various other endocrine glands. Thymus gland - Plays a role in the body's immune system. Thyroid gland - Produces hormones that stimulate body heat production, bone growth, and the body's metabolism. Your endocrine system is a collection of glands that produce hormones...

...The effects of childhood abuse on its victims are penetrating. These effects can be emotional, social, and spiritual. The impact of the abuse depends on the victim and circumstances of the abuse. According to Glaser (2000), besides the psychological effects of childhood abuse, which cause much self defeating behavior in adulthood, there are other more serious, life altering effects. Studies show that many victims of child abuse grow up to be drug addicts and most drug addicts have had an abusive childhood (Umeno, Morita, Ikeda, Koda, & Abe, 2009). It has now been discovered that there is a biochemical reason that this happens. Scientific findings show that being a victim of child abuse can contribute to addiction in adulthood because the abuse can cause profound and possibly irreversible damage to the structure, function and chemistry of the brain. Kaufman, Plotsky, Nemeroff and Charney (2000) claim that because child abuse occurs during a crucial period of brain development, neurobiology reveals that trauma such as physical, emotional and sexual abuse has a substantial impact on the brain. It has also been discovered that the more severe the abuse, the more impact there is on brain function (Bremner, 2005). It has been found that abused children have abnormal brain wave patterns. Child abuse victims suffer damage to important brain structures like the cortex, which is related to rational thinking. Panzer (2008) describes that some of the most dramatic damage is...

...There are no sources in the current document.The purpose of this essay is to explain the role of cytokines in depression. Over the last few decades there have been many controversial hypotheses put forward to explain the observation of depressive symptoms in people, who have a physical injury or are under psychological stress (Schiepers, et al., 2008). Research shows that most controversy was over how the messages from the immune system were interpreted or translated into being a signal to the central nervous system (CNS). While most research agreed that there was a correlation in data between cytokines and depressive symptoms, they did not believe this indicated a causal link (Anisman, 2002). I have chosen to focus one of the most popular theories, the “cytokine theory of depression”, as I believe the research shows that it has a causal link between inflammation, cytokine activity and depressive symptoms (Roque, et al., 2009). This hypothesis recognises and explains the highly integrated processes and mechanisms that a person or animal goes through, from the initial stressor to displaying the depressive symptoms, termed as “sickness behaviour” (Dantzer, 2006). “Sickness Behaviour” is the term given to the symptoms caused by high levels of pro-inflammatory cytokines in the periphery of the body; these symptoms overlap with the general characteristics of depression and include; decreased appetite, increased desire to sleep, cognitive dysfunction, social withdrawal and decreased...

...these stressors.” The manifest anxiety scale was used to obtain the scores of male and female students. The sample consists of 100 students 50 males and 50 females from different colleges of Lahore. Data was gathered from Queen Mary College Lahore, Kinnaird College Lahore, Forman Christen College Lahore, and Punjab College Lahore. In Western countries the vast amount of researches has been conducted on this issue. More researches are needed to investigate the nature of theses stressors for college students and which stressors are most prevalent in college lives. However these researches are not applicable in Pakistan due to cultural, economic, and educational variations. The main objective of current research work was to study the sources of stress among college students. The research used to determine the major sources of stress among college students and also find out the most prevalent stressor in college life and study the nature of these stressors. The Taylor manifest anxiety scale was used Anxiety scale was originally designed by Taylor (1895-1953). The scale is used to identify subjects with high and low anxiety level. In order to study the affects of drive level on performance in a number of experimental conditions. The scale consisted of 40 potentially stressful situations. The scale addressed interpersonal, intrapersonal, academic, and environmental sources of stress. The results show that academic sources of stress being the most frequently reported source.

...associated with direct interference with the endocrine reproductive axis. Examples are those with estrogenic activity or the potential to interact with the aryl hydrocarbon (Ah) receptor. Exposure to toxicants during development is of particular concern because many feedback mechanisms functioning in the adult are absent and adverse effects may be noted at doses lower than those observed in the adult. Endometriosis is a painful reproductive and immunologic disease of women characterized by aberrant location of uterine endometrial cells. It affects approximately 5 million women in the United States from 15 to 45 years of age and often causes infertility. The etiology of this disease is unknown. In a single study with a small number of animals, research has suggested a link between dioxin exposure and the development of endometriosis in rhesus monkeys. The severity of this lesion was dependent on the dose administered. Recently, a small pilot study to test the hypothesis that serum dioxin concentrations have an association with human endometriosis has been reported. No statistically significant correlations between disease severity and serum levels of halogenated aromatic hydrocarbons were found. These preliminary data, admittedly on a limited population, suggest that serum dioxin concentrations may not be related to human endometriosis. Human breast cancer is a major health problem in the United States. While considerable information is available on risk factors for human...
