Gonadotropin-releasing hormone

Hans Zellweger, a Swiss American professor of pediatrics and genetics at the University of Iowa in the mid-1960s described the familial disorder among siblings that was later named after him for the recognition of his discovery, the Zellweger Syndrome. Peroxisomes are cell structures that break down toxic substances and synthesize lipids (fatty acids, oils, and waxes) that are needed for cell function. Peroxisomes are what is needed for normal brain development and its function and it’s what…

Endocrine System The endocrine system is basically the network of glands that secrete hormones into the blood stream which regulates activities of cells or organs. The sexual development and function of the body and the metabolism are two examples of what the endocrine systems does. The major contributors to the endocrine system include the pituitary gland, thyroid, hypothalamus, parathyroid, adrenal glands, pineal body, reproductive glands, and the pancreas. The pituitary gland is…

Lymphocytic Choriomeningitis virus (LCMV) belongs to the Old World arenavirus family of enveloped viruses (Buchmeier et al., 2007). LCMV in particular has served as model organism from many significant studies in the field of immunology such as the Nobel Prize winning study of the Major Histocompatibility Complex (MHC) by Zinkernagel and Doherty (1975). LCMV’s natural reservoirs are the common household rodents (Traub, 1936). Household mice have shown to attain persistent asymptomatic LCMV…

Glucocorticoids are steroid hormones which are produced predominantly in response to stress in the adrenal gland (Davis & Sandman 2010; Korgun et al. 2012). The physiological effects of glucocorticoids occur when the hormone are bind to, and mediated by the glucocorticoid receptor (Erhuma 2012). It plays a wide range of vital physiological roles that are necessary for healthy implantation and pregnancy processes (Korgun et al. 2012). As glucocorticoids are critical in the regulation of the…

specifically chronic glucocorticoid has been associated with a number of neuropsychiatric disorders, specifically depression, PTSD, and even bipolar disorder. Glucocorticoid can activate the glucocorticoid receptor (GR). GR is an intracellular steroid hormone receptor. In the absence of steroid, GR is typically localized to the cytoplasm of the cell where it is bound to…

Four Small Things Four important hormones help you every day to achieve the things that make you happy. Endorphins, serotonin, oxytocin and dopamine are released from the pituitary gland, which is located at the base of the brain. The pituitary gland is part of the endocrine system which is responsible for growth, reproduction, sleep, mood, etc. The pituitary gland is about the size of a pea and is known as the “master gland” since it controls many important functions in the body. Endorphins,…

Reflections 1. Hormones and the brain are powerful influences on human sexual functioning. Perhaps two of the most important portions of the brain in terms of sexual functioning are the hypothalamus and the pituitary gland, which make up the HPG axis. The HPG axis consists of the hypothalamus, pituitary gland, and the gonads – gonads being the testes in males and the ovaries in females. Together, the HPG axis regulates sex hormone production in a negative feedback loop. Three important hormones…

elevated cortisol level is unknown, but it may be involved with loss of bone density in anorexia nervosa(Lo Sauro et al., 2008). Alterations in growth hormone are also present in anorexia nervosa. Levels are more often elevated, but levels of insulin like growth factor (IGF-1) are decreased, indicative of growth hormone resistance. Antidiuretic hormone levels may also be low in anorexia nervosa which may rarely result…

This is an interesting scenario because endocrine system synthase performs as a negative feedback system. This means that when there is an unusually high level of a hormone in the blood, a signal will be sent back and production of that particular hormone will be stopped. The negative feedback system can easily keep all hormones levels at the optimal level for humans. When people train or exercise for a prolonged period of time they must understand the stress they can potentially bring upon…

death. I am going to talk about the effects of the condition on the human body. We also are going learn about the condition more in depth. Hypothyroidism Hypothyroidism is a condition in which your thyroid produce the improper levels of certain hormones that is needed to function properly. Women especially those older than 60 are more likely to have the disease. The disease rarely causes symptoms in the…
