Hormone

different hormones. A hormone is usually a special protein that certain cells in the body make. Once the hormone is made, it enters the blood so it can travel to where ever it is needed in the body to make a specific thing happen. The body continues to make more of the hormone as needed in order to make happen what it is the hormone does. Certain cells make one type of hormone, while other cells make a different type of hormone and so on. Believe it or not, in addition to the sex hormones…

1. Follicle Stimulating Hormone (FSH) - A. production site - anterior pituitary gland B. target organs - female ovaries and male testes C. general effects - females (supports the development of follicles in ovaries, which will then produce estrogen. The follicle will get larger as a result of FSH and will release different estrogen types.) Males (used for the formation of sperm). 2. Luteinizing Hormone (LH) - A. production site - anterior pituitary gland B. target organs - female ovaries and…

Lipstick and Lead Poisoning Throughout history many unhealthy substances, including lead, have been used as ingredients during the various times in the history of makeup. Modern day cosmetics are more controlled, regulated and their ingredients and the potential side effects are more fully understood. However, recent research by the Campaign for Safe Cosmetics and the Food and Drug Administration (FDA) indicate that there are approximately 400+ best-selling lipsticks on the market today that…

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…

Epinephrine, also known as adrenaline, is a medication hormone and neurotransmitter. This medication is used for a few conditions such as anaphylaxis, cardiac arrest and superficial. Epinephrine also releases a hormone secreted by the adrenal glands that increases rates of blood circulation, breathing, and carbohydrate metabolism and prepares muscles for exertion. this is known as adrenaline. Adrenaline is produced and released from the adrenal glands and its major action, together with…

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…

The releasing and inhibiting hormones that are produced and released from hypothalamic neurons are the growth hormone-releasing hormone (GHRH), growth hormone-inhibiting hormone (GHIH), Thyrotropin-releasing hormone (TRH), Corticotropin-releasing hormone (CRH), Gonadotropin-releasing hormone (GnRH), Prolactin-releasing hormone (PRH) and prolactiaen-inhibiting hormone (PIH). These hormones are stimulated and secretion from the anterior pituitary gland.…

The gaseous hormone ethylene is perceived by the ethylene receptors which reside at the endoplasmic reticulum membranes4. In the genetic model plant Arabidopsis, there are five ethylene receptors (ETR1, ERS1, ETR2, ERS2, and EIN4), that fall into two subfamilies depending on functional kinase activity, and a subset of the receptors contains a receiver domain which promotes interaction with CTR15, 6. Interestingly, the receiver domain of ethylene receptors has a remarkable structural similarity…

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…

release of hormones throughout the human body impacts society daily. By definition, hormones are chemicals that are released by glands which circulate in the bloodstream and act as messengers affecting particular cells and organs. With this, hormones affect human behavior. According to emedicinehealth.com, the endocrine system is made up of glands that produce and secrete hormones, chemical substances produced in the body that regulate the activity of cells or organs. This system enables…
