  1. What are the two types of glands in the body
    endocrine and exorine
  2. Exocrine glands ....
    • - sweat, salivary, mucous glands etc.
    • - secretions transported through ducts
    • - function within a particular system of body
  3. exocrine glands ...
    • -secretions placed directly into the blood
    • - make up a whole system of body
    • - blood transports secretions to target tissus for functions
  4. endocrine system ....
    • - secretes hormones that are transported to target tissues via blood
    • - causes changes in metabolic activites in specific cells
    • - exerts effects relatively slowly
    • - has generally prolonged effects
  5. Nervous system ...
    • - transmits neurochemical impulsse via nerve fibers
    • - causes muscles to contract or glands to secrete
    • - exerts effects relatively rapiidly
    • - has gerenally brief effects
  6. Pituitary Glands (hypophysis)
    • - located on inferior aspect of brain
    • - attachetd to hypothalamus by infundibulum

    • - located below larynx
  17. Thyroxne and triiodothyrannine
    • - the two major hormones produced by the endocrine system
    • - increases the rate of protein synthesis and rate of energy release from carbohydrates
    • - regulates rate of growth
  18. calcitonin (thyroclacitonin)
    • - minor hormone in thyroid gland
    • - lowers blood calcium by inhibiting release of calcium from bone tissue
  19. The thyroid gland is two lobes on either side of the trachea connected antarioly by a broad structure called the __________
    isthmus
  20. parathyroid gland
    • - small flattened and embedded in lobes of thyroid glands
    • - has 4 glands
    • - 1 hormone secreted
  21. parthyroid hormone (PTH)
    • - influences bones, intestines and kindeys
    • - causes increase in blood calcium concetration and decres in blood phophate level
  22. Glucogen
    • - stimulates liver and convert glycogen into glucose causing blood glucose level to rise
    • - a hormone secreted by the pancrease
  23. Insulin
    • - promotes movments of glucose through plamsa membranes
    • - stimulates liver to convert glucose into glycogen
    • - promtes transport of amino acids into cells
    • - asissts in synthis of proteins and fats
  24. Adreneal Glands
    • - paried galnds that cap superiof border of kindeys
    • - 2 divisions cortex and medulla
