  • what hormones are produced by the posterior pituitary (neurohyphosis)


    oxytocin and ADH

  • stimulates contractions and milk ejection


    oxytocin

  • increases water reabsorption in kidneys

    reduce urine output


    ADH

  • what hormones are produced by the anterior pituitary (adrenohyphosis)


    GH, TSH, ACTH, FSH, LH, prolactin

  • what are tropic hormones


    hormones that stimulate the release of another hormone

  • stimulates growth, protein synthesis, and cell replication


    growth hormone

  • stimulates thyroid hormone release


    thyroid stimulating hormone - TSH

  • stimulates adrenal cortex to release corticosteroids


    adrenocortitropic hormone

  • stimulates gamete (sex cell) production


    follicle stimulating hormone (FSH)

  • ovulation and hormone production


    leuitinzing hormone - LH

  • stimulates lactation


    prolactin

  • regulates metabolism, growth, and development


    thyroid gland

  • increases metabolic rate


    thyroid hormone

  • decreases blood calcium levels, inhibits osteoclasts, increases calcium excretion


    calcitonin

  • regulates blood calcium levels


    parathyroid gland

  • increases blood calcium levels, stimulates osteoclasts


    parathyroid hormone

  • what does increases osteoclast activity (increased PTH) lead to


    bone resorption (breaking down bone tissue)

  • where are the adrenal glands loated


    on top of kidneys

  • what does ACTH stimulate


    the adrenal cortex

  • what is produced in the adrenal glomerulosa


    aldosterone (mineralcoriticoids)

  • what is produced in the adrenal fasciculata


    coritsol

  • what is produced in the adrenal reticularis


    sex hormones

  • what is produced in the adrenal medulla


    epinephrine and norepinephrine

  • increases blood sodium levels


    aldosterone

  • regulates stress and metabolist


    cortisol

  • what increases blood glucose levels


    glucagon (alpha cells)

  • glycogenolysis


    break down of stored glycogen into glucose to raise glucose levels

  • gluconeogenesis


    production of glucose from non carbohydrates (amino acids) to raise glucose levels

  • glycogenesis


    production of glycogen from glucose

  • glycolysis


    splitting glucose directly into ATP for energy

  • what causes goiter


    low iodine levels reduce T3 and T4 hormones , increases TSH , thyroglobulin accumulation causes goiter
