9415109901endocrine systembody system that includes internal organs that secrete hormones0
9415135461endocrinologyscientific study of hormones and endocrine organs1
9415139666hormoneschemical substances that are secreted by endocrines cells into the extracellular fluids and regulate the metabolic activity of other cells in body.2
9415150466amino acid-bases molecules3
9415150467steroids-made from cholesterol -include sex hormones made by the gonads and the hormones produced by the adrenal cortex4
9415180046prostaglandinslocal hormones -made from highly active lipids release from nearly all cell membranes5
9415207256target cells or target organsa given hormone affects only certain tissue cells or organs6
9415236801second messenger systemintracellular molecule generated by binding of a chemical to a membrane receptor; mediates intracellular responses7
9415254840negative feedback mechanismschief means of regulating blood levels of nearly all hormones8
9415284748hypothalamusmajor endocrine organ because it produces several hormones.9
9415303797ductless glandsendocrine glands -produce hormones that they release into blood or lymph10
9415565563pituitary gland-size of a pea -the neuroendocrine gland located beneath the brain that serves a variety of functions including regulations of the gonads, thyroid, adrenal cortex, water balance, and lactation.11
9415611175tropic hormonesstimulate their target organs, which are also endocrine glands,to secrete their hormones, which in turn exert their effects on other body organs and tissues.12
9415634600growth hormonegeneral metabolic hormone -important role in determining final body size -is a protein sparing and anabolic hormone that causes amino acids to be built into proteins and stimulates most target cells to grow in size and divide13
9415658238pituitary dwarfismor growth hormone deficiency, is a condition in which the pituitary gland does not make enough growth hormone. This results in a child's slow growth pattern and an unusually small stature (below average height).14
9415676097gigantismindividual becomes extremely tall; 8 to 9 feet is common. -body proportions are fairly normal15
9415700561acromegalypituitary gland produces too much growth hormone during adulthood. -bones increase in size16
9415758530prolactinprotein hormone structurally similar to growth hormone. -only known target in humans is the breast -after childbirth, it stimulates and maintains milk production by mothers breasts. -function in men=unknown17
9415805907adrenocorticotropic hormone (ACTH)regulates the endocrine activity of the cortex position of the adrenal gland18
9415817843thyroid-stimulating hormone(TSH)/ thyrotropic hormone (TH)influences the growth and activity of the thyroid gland19
9415827265gonadotropic hormonesregulate the hormonal activity of the gonads20
9415830556gonadstestes and ovaries21
9415846607follicle-stimulating hormone (FSH)(women): stimulates follicle development in the ovaries. as the follicles mature, they produce estrogen, and eggs are readied for ovulation (men): stimulates sperm development by the testes.22
9415868129luteinizing hormonetriggers ovulation of an egg from the ovary and causes the ruptured follicle to produce progesterone and some estrogen. in men, it stimulates tester one production by the interstitial cells of the testes23
9415899311sterility24
9415918883releasing and inhibiting hormonesA hormone that inhibits the secretion of another hormone. The hypothalamus produces several hormones that inhibit the release of hormones by the anterior lobe of the pituitary (adenohypophysis).25
9415918884oxytocin-released in significant amounts only during childbirth and in nursing women -stimulates powerful contraction of the uterine muscle during labor, during sexual relations, and during breastfeeding. -causes milk ejection in nursing women -induce labor or to hasten labor -stop postpartum bleeding26
9415923088neurosecretory cellsnerve cells, such as those of the hypothalamus, which elaborate a chemical substance that influences the activity of another structure27
9415925752antidiuretic hormone (ADH)chemical that inhibits or prevents urine production -causes kidney to reabsorb more water from the forming urine -also increases blood pressure by causing constriction of the arterioles(small arteries)28
9415927619vasopressinis a man-made form of a hormone called "anti-diuretic hormone" that is normally secreted by the pituitary gland. - acts on the kidneys and blood vessels.29
9416076062diabetes insipidusis an uncommon disorder that causes an imbalance of water in the body. This imbalance leads to intense thirst even after drinking fluids, and excretion of large amounts of urine .30
9416083458thyroid glandThe thyroid gland is located in the lower part of the neck, below the Adam's apple, wrapped around the trachea (windpipe). -It has the shape of a butterfly: two wings (lobes) attached to one another by a middle part called the isthmus. -releases hormones that control metabolism:way body uses energy31
9416168399folliclesthyroid gland is composed of these hollow structures -store sticky colloidal material32
9416177090thyroid hormoneplay vital roles in regulating the body's metabolic rate, heart and digestive functions, muscle control, brain development and maintenance of bones.33
9416179585thyroxine (t4)is the main hormone secreted into the bloodstream by the thyroid gland34
9416187588triiodothyronine (t3)A hormone that is made by the thyroid gland -it is the most powerful thyroid hormone, and it affects almost every process in the body, including body temperature, growth, and heart rate35
9416271866goitersenlargement of the thyroid gland because the diet is deficient in iodine.36
9416273999cretinisma congenital disease due to absence or deficiency of normal thyroid secretion, characterized by physical deformity, dwarfism, and mental retardation, and often by goiter.37
9416274000myxedemaboth physical and mental sluggishness( however mental retardation doesn't occur). -signs of puffy face, fatigue, poor muscle tone, low body temp., obesity, and dry skin.38
9416276009graves diseasealso known as toxic diffuse goiter, is an autoimmune disease that affects the thyroid. It frequently results in and is the most common cause of hyperthyroidism. It also often results in an enlarged thyroid.39
9416277704exophthalmosalso known as proptosis, is a medical term for a bulging or protruding eyeball or eyeballs. It's most often caused by thyroid eye disease40
9416348688calcitonindecreases blood calcium level by causing calcium to be deposited in the bones41
9416351042parafollicular cells42
9416386672parathyroid glandtiny masses of glandular tissue most often found on the posterior surface o the thyroid gland43
9416397128parathyroid hormone/ parathormonemost important regulator of calcium ion homeostasis of the blood.44
9416414651tetanya condition marked by intermittent muscular spasms, caused by malfunction of the parathyroid glands and a consequent deficiency of calcium45
9416432106adrenal glandstwo bean shaped that curve over the top of the kidneys46
9416451653adrenal cortexte outer part of the gland—produces hormones that are vital to life, such as cortisol (which helps regulate metabolism and helps your body respond to stress) and aldosterone (which helps control blood pressure47
9416478367androgensmale sex hormones48
9416480470estrogensfemale sex hormones49
