Question | Answer |
---|---|
antagonistic | acting in opposition; mutually opposing |
electrolyes | mineral salts(Na+,K+,Ca2+) that carry an electrical charge in solution |
glucagon | hormone produced by pancreatic alpha cells that increases the blood glucose level by stimulating the liver to changed stored glycogen (a starch form of sugar) to glucose [glucagon opposes insulin; reverse hypoglycemic reactions in insulin shock] |
glucose | simple sugar that is the end product of carbohydrate digestion |
homeostatis | relative constancy or balance in the internal environment of the body, maintained by processes of feedback and adjustment in response to external or internal changes |
hormones | chemical substances produced by specialized cells of the body that are released slowly in minute amounts directly into the bloodstream |
insulin | hormone produced by pancreatic beta cells that acts to remove sugar (glucose) from the blood by promoting its storage in tissues as carbohydrates (glycogen) |
sympathomimetic | agent that mimics the effects of the sympathetic nervous system; epinephrine and norepinephrine are sympathomimetic hormones because they produce effects that mimic those brought about by the sympathetic nervous system |
target | structure, organ, or tissue to which something is directed |
ACTH | the hormone andrenocorticotropic hormone from adenohypophysis AP acts upon the adrenal cortex, promotes secretions of some hormones by adrenal cortex, cortisol specifically [HYPER~CUSHING DISEASE] |
FSH | the hormone follicle-stimulating hormone from adenohypophysis AP acts upon: ovaries to stim. egg prod, increases secretion of estrogen; & testes to stim. sperm prod [HYPO~FAILURE of SEXUAL MATURATION] |
GH | the hormone somatotropin, growth hormone, from adenohypophysis AP acts upon bone, cartilage, liver, muscle, and other tissues-stimulates somatic growth; increases use of fats for energy [HYPO~PITUITARY DWARFISM] [HYPER~GIGANTISM & ACROMEGALY] |
LH | the hormone luteinizing hormone from adenohypophysis AP acts upon: ovaries-promotes ovulation; stim. prod. of estrogen & progesterone; testes-promotes secretion of testosterone [HYPO~FAILURE OF SEXUAL MATURATION] |
Prolactin | hormone from adenohypophysis AP acts upon breast-in conj w/ other hormones to promote lactation [HYPER~GALACTORRHEA] |
TSH | the hormone thyroid-stimulating hormone from adenohypophysis AP acts upon: thyroid gland-stim. secretion of thyroid hormone [HYPO~CRETINISM & MYXEDEMA] [HYPER~GRAVES as indicated by exophthalmos] |
