Document Summary

Gonads: difference between exocrine and endocrine glands, endocrine glands occur within the body and need glands, no duct system; uses circulatory system as means of transport. Not direct target tissue: dwarfism (hypo) and gigantism (hyper) and. Iodine + thyroglobulin sugar vesicles = final form: number of iodine molecules = nomenclature, t3, made from t4, 3 iodine vesicles, released at target tissues from the breakdown of. T4: disorders associated with the thyroid gland, goiter- lack of iodine in the diet. 6: cretism- hypothyroidism in infants, myxedema- hypothyroidism syndrome in adults, graves disease- hyperthyroidism. Auto-immune; immune system attacks the thyroid: exophthalmos- symptom of graves disease. Released by the medulla: catecholamines, epinephrine, norepinephrine, fight or flight: stress hormones. Damage from prolonged use: glycogen glucose. Corticosteroids: released by the cortex: mineralocorticoids, aldosterone, glucocorticoids, cortisone and cortisol, sexhormones, estrogen, progesterone, testosterone, disorders of the adrenal gland, addison"s disease- hypersecretion of glucocorticoids and other corticoids.
