Terms in this set (53)
Either of two small endocrine glands, one located above each kidney. The outer portion, or cortex, secretes steroid hormones (corticosteroids). The inner portion, or medulla, secretes epinephrine and norepinephrin
a hormone secreted by the pituitary gland and stimulating the adrenal cortex.
a male sex hormone, such as testosterone
develops from a fold of tissue at the roof of the embryonic mouth; this tissue grows upward toward the brain and eventually loses its connection to the mouth
Anti diuretic Hormone(ADH)
a pituitary hormone that acts to promote the retention of water by the kidneys and increase blood pressure.
a hormone that is secreted by neurosecretory cells of the insect brain and that stimulates the prothoracic glands to secrete ecdysone. 2 : any of various hormones (as serotonin) produced in or acting on the vertebrate brain or central nervous system —not usually used technically.
a hormone secreted by the thyroid that has the effect of lowering blood calcium.
any of a class of aromatic amines that includes a number of neurotransmitters such as epinephrine and dopamine.
any of a group of steroid hormones produced in the adrenal cortex or made synthetically. There are two kinds: glucocorticoids and mineralocorticoids. They have various metabolic functions and some are used to treat inflammation.
the most common form of diabetes, caused by a deficiency of the pancreatic hormone insulin, which results in a failure to metabolize sugars and starch. Sugars accumulate in the blood and urine, and the byproducts of alternative fat metabolism disturb the acid-base balance of the blood, causing a risk of convulsions and coma.
a steroid hormone that controls molting in insects and other arthropods.
hormone-secreting organs, ductless glands, secreting chemical messengers into the extracellular fluid
any of a group of hormones secreted within the brain and nervous system and having a number of physiological functions. They are peptides that activate the body's opiate receptors, causing an analgesic effect.
a hormone secreted by the adrenal glands, especially in conditions of stress, increasing rates of blood circulation, breathing, and carbohydrate metabolism and preparing muscles for exertion.
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.
a hormone secreted by the anterior pituitary gland that promotes the formation of ova or sperm.
a hormone formed in the pancreas that promotes the breakdown of glycogen to glucose in the liver.
any of a group of corticosteroids (e.g., hydrocortisone) that are involved in the metabolism of carbohydrates, proteins, and fats and have anti-inflammatory activity.
any of a group of hormones secreted by the pituitary that stimulate the activity of the gonads.
a substance, such as a vitamin or hormone, that is required for the stimulation of growth in living cells.
a hormone that stimulates growth in animal or plant cells, especially (in animals) a hormone secreted by the pituitary gland.
stimulate cell proliferation and differentiation
is a chemical signal that is secreted into the extracellular fluid, is carried by the circulatory system and communicates regulatory messages within 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
groups of pancreatic cells secreting insulin and glucagon.
any of a number of hormones regulating larval development in insects and inhibiting metamorphosis.
a hormone secreted by the anterior pituitary gland that stimulates ovulation in females and the synthesis of androgen in males.
a hormone secreted by the pituitary gland that is involved in pigmentation changes in some animals.
a hormone secreted by the pineal gland that inhibits melanin formation and is thought to be concerned with regulating the reproductive cycle.
a corticosteroid, such as aldosterone, that is involved with maintaining the salt balance in the body
the effector response reduces the initial stimulus, and eventually the response ceases
specialized nerve cells that release hormones into the blood via extracellular fluid
Nitric Oxide (NO)
regulator-is a gas
a hormone that is released by the adrenal medulla and by the sympathetic nerves and functions as a neurotransmitter. It is also used as a drug to raise blood pressure.
a hormone released by the pituitary gland that causes increased contraction of the uterus during labor and stimulates the ejection of milk into the ducts of the breasts.
a large gland behind the stomach that secretes digestive enzymes into the duodenum. Embedded in the pancreas are the islets of Langerhans, which secrete into the blood the hormones insulin and glucagon.
are small endocrine glands in the neck of humans and other tetrapods that produce parathyroid hormone. Humans usually have four parathyroid glands, variably located on the back of the thyroid gland, although considerable variation exists.
a gland next to the thyroid that secretes a hormone ( parathyroid hormone ) that regulates calcium levels in a person's body.
a pea-sized conical mass of tissue behind the third ventricle of the brain, secreting a hormonelike substance in some mammals.
lima bean sized organ located at the base of the hypothalamus
extension of the hypothlamus that grows downward toward the mouth during embryonic development
a natural or synthetic steroid hormone, such as progesterone, that maintains pregnancy and prevents further ovulation during pregnancy.
a hormone released from the anterior pituitary gland that stimulates milk production after childbirth.
group of regulators, modified fatty acids, derived from lipids in the plasma membrane
Signal Transduction Pathway
when a hormone binds to its receptor, a series of changes in cellular proteins that converts an extracellular chemical signal to a specific intracellular response
a steroid hormone that stimulates development of male secondary sexual characteristics, produced mainly in the testes, but also in the ovaries and adrenal cortex.
a hormone secreted by the pituitary gland that regulates the production of thyroid hormones.
the main hormone produced by the thyroid gland, acting to increase metabolic rate and so regulating growth and development.
a thyroid hormone similar to thyroxine but having greater potency.
Hormones that regulate the function of endocrine organs, coordinate endocrine signaling throughout the body
any of a group of vitamins found in liver and fish oils, essential for the absorption of calcium and the prevention of rickets in children and osteomalacia in adults. They include calciferol ( vitamin D2 ) and cholecalciferol ( vitamin D3 )
