    p 497
    follicle stimulating hormone (FSH)
  21. a hormone that the anterior pituitary secretes that controls formation of the corpus luteum in females and testosterone secretion in males

  22. hormone of the posterior pituitary gland that enhances water conservation in the kidneys; ADH, vasopressin
    antidiuretic hormone
  23. hormone released by the posterior lobe of the pituitary gland that contracts smooth muscles in the uterus and mammary glands
  24. endocrine gland just below the larnyx and in front of the trachea that secretes thyroid hormones
    thyroid gland
  25. narrow connection between two larger parts.
  26. two important thyroid hormones that affect cellular metabolic rates
    thyroxine and triiodothyronine
  27. hormone secreted by the thyroid gland (T4)
  28. hormone secreted by the thyroid gland (T3); five times more potent that T4
  29. thyroid hormone that regulates blood calcium concentration; helps lower concentrations of calcium and phosphate ions by decreasing the rate at chich they leave the bones and enter extracellular fluids by inhibiting bone destruction by osteoclasts; increases excretion by kidneys.
  30. hyperthyroidism and graves disease are caused by:
  31. hashimoto diesase (antibodies against self attck thyroid cells resulting in hypothyroidism); hypothyroidism, and simple goiter are caused by:
  32. symptoms: stunted growth, abnormal bone formation, mental retardation, low body temperature, sluggishness
    cretinism (infantile - hypothyroidism)
  33. symptoms: low metabolic rate, sensitivity to cold, sluggishness, poor appetite, swollen tissues, mental dullness
    myxedema (adult - hypothyroidism)
  34. symptoms: autoantibodies (against self) bind TSH receptors on thyroid cell membranes, mimicking action of TSH, overstimulating gland (hyperthyroidism); exopthalmia (protusion of the eyes) and goiter
    graves disease
  35. symptoms: high metabolic rate, sensitivity to heat, restlessness, hyperactivity, weight loss, protruding eyes, goiter
  36. one of four small endocrine glands embedded in the posterior part of the thyroid gland.
    parathryoid gland
  37. hormone secreted by the parathyroid glands that helps regulate the level of blood calcium and phosphate ions
    parathyroid hormone PTH
  38. endocrine gland on the superior portion of each kidney
    adrenal gland
  39. inner part of the adrenal gland
    adrenal medulla
  40. outer part of the adrenal gland
    adrenal cortex
  41. epinephrine and norpinephrine are hormones of the
    adrenal medulla
  42. hormone the adrenal medulla secretes during times of stress
  43. neurotransmitter released from the axons of some nerve fibers
  44. produces aldosterone, cortisol, and sex hormones
    adrenal cortex
  45. adrenal cortical hormone that regulates sodium and potassium ion concentrations and fluid volume

    • glucocorticoid secreted by the adrenal cortex; inhibits synthesis of protein in tissues increasing blood concentration of amino acids, promotes the release of fatty acids from lipids to use as energy, and stimulates liver cells to synthesize glucose increasing blood glucose concentrations
    • cortisol
  46. supplement sex hormones from the gonads; may be converted into estrogens
    adrenal androgens
  47. glandular organ in the abdominal cavitiy that secretes hormones and digestive enzymes

  49. hormone the pancreatic islets secrete that stimulates cells to take up glucose
  50. hormone secreted by the pancreatic islets that inhibits the release of growth hormone
  51. hormone that the pineal gland secretes
  52. pattern ofrepeated activity associated with the cycles of night and day
