    • heat production
    • CHO and fat metabolism
  12. Metabolic rate, heat productiona dn CHO and lipid metabolism are regulated by what hormone?
    Thyroid hormone (thyroxine and T3)
  13. Throid hormone refers to what?
    Thyroxine (T4) and Triiodothyronine (T3)
  14. The adrenal gland has a primary function in response to what?
  15. The adrenal gland has two major components that re:
    the medulla and the cortex
  16. The adrenal cortex produces what hormone in repsonse to stress?
  17. Cortisol is produced by what part o fthe adrenal gland?
  18. The cortex responds to what type of stress?
  19. Which part of the adrenal gland responds to chronic stress?
  20. Chronic stress causes the adrenal gland to produce what hormone?
  21. What does cortisol do in response to chronic stress?
    maintains blood glucose by stimulating gluconeogenesis from protein and fat?
  22. Cortisol stimulates the production of gluconeogenesis from what nutrients?
    protein and fat
  23. What part of the adrenal gland responds to acute stress?
    the medulla
  24. The adrenal medulla responds to what type of stress?
  25. The adrenal medulla produces what hormone
  26. What stimulation of the adrenal medulla causes the release of catecholamines?
    sympathetic stimulation
  27. Sympathetic stimulation of the adrenal medulla causes what?
    The release of Catecholamines
  28. What do Catecholamines do?
    They are excitatory and stimulate CHO metabolsim and cardiac output
  29. What adrenal hormone causes CHO metabolism and increased cardiac output?
  30. Which adrenal cortx zone produces aldosterone?
    zona glomerulosa
  31. The zona glomerulosa of the adrenal gland produces what?
  32. the zona fasciculata produces what hormones in the adrenal cortex?
    Cortison and androgens
