Endocrine System Flashcards
a mechanism that includes the monitoring for specific homeostatic levels and a signal to a gland. this signal stimulates or inhibits the gland’s secretion in order to maintain homeostasis or cause compensation that returns the level to homeostasis
negative feedback
the gland in the neck that secretes hormones that regulate growth, development, and metabolic rate
thyroid gland
an endocrine gland in the neck that produces parathyroid hormone
parathyroid gland
the lymphoid organ that produces T cells
thymus
a gland above the kidney that produces hormones to regulate heart rate, blood pressure, and other functions
adrenal
the gland of the digestive and endocrine systems that produces insulin and secretes pancreatic juices
pancreas
a small gland near the center of the brain that secretes melatonin
pineal gland
the monomers used to build polysaccharides; also molecules made of two or a few monosaccharide units that are used for fuel in the body
sugars
a gland that secretes hormones. a duct-less gland
endocrine gland
a polar, water-soluble hormone released by the adrenals in response to stress (adrenaline)
epinephrine
pathologically high blood sugar levels that result from a pancreatic hormone regulation malfunction diastole. the portion of the cardiac cycle in which the heart refills with blood
diabetes
a malfunction of regulatory feedback loops leading to the overproduction of thyroid hormone
hyperthyroidism
excessive growth resulting from overproduction of growth hormone
gigantism
secretion of the anterior pituitary that stimulates tissue growth (somatotropin)
growth hormone
secretion from the pituitary gland that increases the amount of water able to be reabsorbed from a collecting duct
antidiuretic hormone
