Terms in this set (35)ACTH ACTH stands for adrenocorticotropic hormone, it is a plypeptide tropic hormone produced and secreted by the anterior pituitary gland. The function of ACTH is to regulate levels of the steroid hormone cortisol, which released from the adrenal gland. ADH ADH stands for Antidiuretic hormone, it is a relatively small molecule that is released by the pituitary gland at the base of the brain after being made nearby, in the hypothalamus. ADH has an antidiuretic action that prevents the production of dilute urine. ADH is also known as vasopressin. adrenal gland The adrenal glands, also known as suprarenal glands means located superior part of the kidney, are endocrine glands that produce a variety of hormones including adrenaline and the steroids aldosterone and cortisol. They are found above the kidneys. The suprarenal glands require a large supply of blood and release hormones directly into the bloodstream. The superior suprarenal arteries are multiple small branches from the inferior phrenic artery, whereas the middle suprarenal artery is a direct branch from the abdominal aorta. adrenaline A stress hormone produced within the adrenal gland that quickens the heart beat, strengthens the force of the heart's contraction, and opens up the bronchioles in the lungs, among other effects. The secretion of adrenaline is part of the human 'fight or flight' response to fear, panic, or perceived threat. androgens Androgens are a male sex hormone that promotes the development and maintenance of the male sex characteristics. The major androgen is testosterone. calcitonin calcitonin is a hormone produced by the thyroid gland that lowers the levels of calcium and phosphate in the blood and promotes the formation of bone. Bone is in a constant state of remodeling. Old bone is removed by cells called osteoclasts, and new bone is added by cells called osteoblasts. corticoids Corticosteroids are a class of steroid hormones that are produced in the adrenal cortex of vertebrates, as well as the synthetic analogues of these hormones. endocrine glands The endocrine system is a chemical messenger system consisting of hormones, the group of glands of an organism that secrete those hormones directly into the circulatory system to be carried towards distant target organs, and the feedback loops of homeostasis that the hormones drive. estrogen any of a group of steroid hormones that promote the development and maintenance of female characteristics of the body. Such hormones are also produced artificially for use in oral contraceptives or to treat menopausal and menstrual disorders. exocrine glands Exocrine glands are glands that produce and secrete substances onto an epithelial surface by way of a duct. Examples of exocrine glands include sweat, salivary, mammary, ceruminous, lacrimal, sebaceous, and mucous. FSH Sometimes, elevated follicle-stimulating hormone (FSH) levels are measured to confirm menopause. When a woman's FSH blood level is consistently elevated to 30 mIU/mL or higher, and she has not had a menstrual period for a year, it is generally accepted that she has reached menopause. gonads a reproductive gland (such as an ovary or testis) that produces gametes. GH (somatotropin) Growth hormone, also known as somatotropin, is a peptide hormone that stimulates growth, cell reproduction, and cell regeneration in humans and other animals. It is thus important in human development. hormones a regulatory substance produced in an organism and transported in tissue fluids such as blood or sap to stimulate specific cells or tissues into action. a synthetic substance with an effect similar to that of an animal or plant hormone. a person's sex hormones as held to influence behavior or mood. insulin Insulin is a peptide hormone secreted by the pancreas in response to increases in blood sugar, usually following a meal. ... Once insulin is in the blood, it shuttles glucose (carbohydrates), amino acids, and blood fats into the cells of the body. a hormone produced in the pancreas by the islets of Langerhans that regulates the amount of glucose in the blood. The lack of insulin causes a form of diabetes. islets of langerhans Pancreatic islets, also called islets of Langerhans, are tiny clusters of cells scattered throughout the pancreas. The pancreas is an organ about the size of a hand located behind the lower part of the stomach. Pancreatic islets contain several types of cells, including beta cells, that produce the hormone insulin. LH In females, an acute rise of LH ("LH surge") triggers ovulation and development of the corpus luteum. In males, where LH had also been called interstitial cell-stimulating hormone (ICSH), it stimulates Leydig cell production of testosterone. It acts synergistically with FSH. Luteinizing hormone is a hormone produced by gonadotropic cells in the anterior pituitary gland. In females, an acute rise of LH triggers ovulation and development of the corpus luteum. negative feedback Negative feedback is a reaction that causes a decrease in function. It occurs in response to some kind of stimulus. Often it causes the output of a system to be lessened; so, the feedback tends to stabilize the system. This can be referred to as homeostatis, as in biology, or equilibrium, as in mechanics. it is the diminution or counteraction of an effect by its own influence on the process giving rise to it, as when a high level of a particular hormone in the blood may inhibit further secretion of that hormone, or where the result of a certain action may inhibit further performance of that action. ovary Gross Anatomy. The ovaries are the female pelvic reproductive organs that house the ova and are also responsible for the production of sex hormones. They are paired organs located on either side of the uterus within the broad ligament below the uterine (fallopian) tubes. ocytocin Medical Definition of Oxytocin. Oxytocin is a peptide (a compound consisting of 2 or more amino acids) that is secreted by the hypothalamus and transported to the posterior lobe of the pituitary gland at the base of the brain. Oxytocin is related to another hormone called vasopressin. pancreas Anatomy of the pancreas. The pancreas is an elongated, tapered organ located across the back of the abdomen, behind the stomach. The right side of the organ, called the head, is the widest part of the organ. It lies in the curve of the duodenum, the first section of the small intestine. parathormone Parathyroid hormone, also called parathormone or parathyrin, is a hormone secreted by the parathyroid glands that is important in bone remodeling, which is an ongoing process in which bone tissue is alternately resorbed and rebuilt over time. parathyroid glands The parathyroid glands are four tiny glands, located in the neck, that control the body's calcium levels. Each gland is about the size of a grain of rice (weighs approximately 30 milligrams and is 3-4 millimeters in diameter). The parathyroids produce a hormone called parathyroid hormone. Although the parathyroid glands are located next to (and sometimes inside) the thyroid gland, they have no related function. The thyroid gland regulates the body's metabolism and has no effect on calcium levels while parathyroid glands regulate calcium levels and have no effect on metabolism. pituitary gland The pituitary gland is a tiny organ, the size of a pea, found at the base of the brain. As the "master gland" of the body, it produces many hormones that travel throughout the body, directing certain processes or stimulating other glands to produce other hormones. The pituitary gland is a pea-sized structure located at the base of the brain, just below the hypothalamus, to which it is attached via nerve fibers. It is part of the endocrine system and produces critical hormones, which are chemical substances that control various bodily functions. progesterone Progesterone, hormone secreted by the female reproductive system that functions mainly to regulate the condition of the inner lining (endometrium) of the uterus. Progesterone is produced by the ovaries, placenta, and adrenal glands. In general, normal serum progesterone test results fall in the following ranges: men, postmenopausal women, and women at the beginning of their menstrual cycle: 1 ng/mL or under. women in the middle of their menstrual cycle: 5 to 20 ng/mL. pregnant women in their first trimester: 11.2 to 90 ng/mL. prolactin Prolactin, also known as luteotropic hormone or luteotropin, is a protein that is best known for its role in enabling mammals, usually females, to produce milk. One of the main regulators of the production of prolactin from the pituitary gland is the hormone called dopamine, which is produced by the hypothalamus, the part of the brain directly above the pituitary gland. Dopamine restrains prolactin production, so the more dopamine there is, the less prolactin is released. prostaglandins The prostaglandins are a group of physiologically active lipid compounds having diverse hormone-like effects in animals. Prostaglandins have been found in almost every tissue in humans and other animals. One of a number of hormone-like substances that participate in a wide range of body functions such as the contraction and relaxation of smooth muscle, the dilation and constriction of blood vessels, control of blood pressure, and modulation of inflammation. TSH Thyroid-stimulating hormone is a pituitary hormone that stimulates the thyroid gland to produce thyroxine, and then triiodothyronine which stimulates the metabolism of almost every tissue in the body. Medical Definition of Thyroid stimulating hormone. Thyroid stimulating hormone: A hormone produced by the pituitary gland at the base of the brain in response to signals from the hypothalamus gland in the brain. ... This mechanism maintains a relatively constant level of thyroid hormones circulating in the blood. target organ cells target organ cells are secreted from the glands of the endocrine system, they are specific in that each hormone causes a response in a specific target organ or group of cells, rather than on the body as a whole. Exocrine hormones are secreted via a duct into the blood and usually effect a distant organ or tissue. Most hormones circulate in blood, coming into contact with essentially all cells. However, a given hormone usually affects only a limited number of cells, which are called target cells. A target cell responds to a hormone because it bears receptors for the hormone. testes Testicles, also called testes or balls, are oval-shaped organs that sit in a sac that hangs behind the penis. The main job of testicles is to make and store sperm and produce testosterone. Testosterone is the male hormone that's responsible for the changes that occur during puberty. testosterone Testosterone is a medication and naturally occurring steroid hormone. It is used to treat male hypogonadism and certain types of breast cancer. It may also be used to increase athletic ability in the form of doping. A small percentage of testosterone is made in the adrenal glands on top of our kidneys. Testosterone is a sex hormone that plays important roles in the body. In men, it's thought to regulate sex drive (libido), bone mass, fat distribution, muscle mass and strength, and the production of red blood cells and sperm. A small amount of circulating testosterone is converted to estradiol, a form of estrogen. thymus The thymus gland, located behind your sternum and between your lungs, is only active until puberty. After puberty, the thymus starts to slowly shrink and become replaced by fat. Thymosin is the hormone of the thymus, and it stimulates the development of disease-fighting T cells. a lymphoid organ situated in the neck of vertebrates that produces T cells for the immune system. The human thymus becomes much smaller at the approach of puberty. thyroid gland The thyroid gland is an endocrine gland in your neck. It makes two hormones that are secreted into the blood: thyroxine and triiodothyronine. These hormones are necessary for all the cells in your body to work normally. a large ductless gland in the neck that secretes hormones regulating growth and development through the rate of metabolism. a large cartilage of the larynx, a projection of which forms the Adam's apple in humans. thyroxine Thyroxine is a hormone the thyroid gland secretes into the bloodstream. ... Thyroxine plays a crucial role in heart and digestive function, metabolism, brain development, bone health, and muscle control. It affects almost all of the body's systems, which means proper thyroxine levels are vital for health. vasopressin Vasopressin (arginine vasopressin, AVP; antidiuretic hormone, ADH) is a peptide hormone formed in the hypothalamus, then transported via axons to the posterior pituitary, which releases it into the blood. ... This increases blood volume, cardiac output and arterial pressure. A secondary function of AVP is vasoconstriction. Sets with similar termsCh 9 Vocab.

The adrenal cortex—the outer layer of the gland—produces mineralocorticoids, glucocorticoids, and androgens. The adrenal medulla at the core of the gland produces epinephrine and norepinephrine.
Where are the adrenal glands located in reference to the kidneys?There are two adrenal glands, one on top of each kidney. The outer part of each gland is the adrenal cortex and the inner part is the adrenal medulla.
What gland is located on the superior side of the kidney?An adrenal gland is located on top of each kidney. Like many glands, the adrenal glands work hand-in-hand with the hypothalamus and pituitary gland. The adrenal glands make and release corticosteroid hormones and epinephrine that maintain blood pressure and regulate metabolism.
Where are the adrenal glands located quizlet?The two adrenal glands are triangular-shaped glands located on top of each kidney. The adrenal glands are made up of two parts. The outer part is called the adrenal cortex, and the inner part is called the adrenal medulla.
