thyroxine
secreted by the thyroid gland, t4 increases metabolism in cells
triiodothyronine
secreted by the thyroid gland, t3 increases metabolism
vasopressin
secreted by the posterior lobe of the pituitary gland, increases water reabsorption and raises blood pressure

hormones derived from an amino acid and secreted by the adrenal medulla
corticosteroids
hormones produced by the adrenal cortex
electrolyte
