  32. cortisol
    secreted from adrenal cortex, regulates carbohydrate metabolism
  33. insulin
    lowers blood sugar levels by allowing sugar to enter individual cells
  34. glucagon
    raises blood sugar by stimulating liver to release stored sugar back into bloodstream
  35. parathyroid/o
    • parathyroid gland
    • are four small glands located on posterior surface of thyroid gland; secretes parathyroid hormone to raise blood levels of calcium
  36. melatonin
    plays a role in regulating body's circadian rhythm (24 hour clock)
  37. anterior lobe
    part of pituitary gland; secretes growth hormone, thyroid-stimulating hormone, adrenocorticotropin hormone, prolactin, melanocyte-stimulating hormone and follicle-stimulating hormone and luteinizing hormonw
  38. thyroid-stimulating hormone
    secreted from anterior lobe of pituitary gland, regulates activity of thyroid gland
  39. adrenocorticotropin hormone
    secreted from anterior lobe of pituitary gland, regulates activity of adrenal cortex
  40. prolactin
    secreted from anterior lobe of pituitary gland; stimulates milk production by breast
  41. melanocyte-stimulating hormone
    secreted from anterior lobe of pituitary gland; stimulates melanoctyes to produce more melanin
  42. follicle-stimulating hormone and luteinizing hormone
    secreted from anterior lobe of pituitary gland; work together to regulate activity of ovary or testes
  43. posterior lobe of pituitary gland
    secretes antidiuretic hormone and oxytocin
  44. antidiuretic hormone
    secreted from posterior lobe of pituitary gland; regulates volume of water in body
  45. oxytocin
    secreted from posterior lobe of pituitary gland; stimulates uterine contractions during labor and birth
  46. acromegaly
    chronic condition developing in adults with excessive growth hormone; results in elongation and enlargement of bones of head and extremities
  47. adrenal feminization
    development of female secondary sexual characteristics (such as breasts) in male as result of increased estrogen secretion by adrenal cortex
  48. adrenal virilism
    development of male secondary sexual characteristics (such as deeper voice and facial hair) in female as result of increased androgen secretion by adrenal cortex
  49. corticosteroids
    in addition to its normal function , these hormones secreted by adrenal cortex also have strong anti-inflammatory action; can be used to treat severe chronic inflammatory diseases such as rheumatoid arthritis
  50. dwarfism
    being excessively short in height; can result from lack of growth hormone
  51. exophthalmos
    condition in which eyeballs protrude, such as in Graves disease; commonly caused by hypersecretion of thyroid hormones
  52. fasting blood sugar
    • (FBS)
    • blood test to measure amount of sugar in bloodstream after a 12 hour fast
  53. gigantism
    excessive growth of body due to hypersecretion of growth hormone in a child or teenager
  54. glucose tolerance test
    • (GTT)
    • test for initial diagnosis of diabetes mellitus; pt is given dose of glucose; then blood samples are taken at regular intervals to determine pt ability to use glucose properly
  55. goiter
    enlargment of the thyroid gland
  56. Graves disease
    condition reulting from hypersecretion of thyroid hormones; symptoms include exophthalmos and goiter

    • also called type 1 diabetes mellitus; tends to develop early in life; pancreas stops producing insulin; can be autoimmune disease; pt must take insulin injections
  59. noninsulin-dependent diabetes mellitus
    also called type 2 diabetes mellitus; typically develops later in life; pancreas produces normal to high levels of insulin but cells fail to respond; pt can take medication to improve insulin function
