- b Include Triiodothryronine or T3 and Tetraiodothyronine or T4 or thyroxine. Transported in blood. Bind with intracellular receptor molecules and initiate new protein synthesis. Increase rate of glucose, fat, protein metabolism in many tissues thus increasing body temperature. Normal growth of many tissues dependent on thyroid hormones.

- c Regulates secretory activity of pituitary gland through neurohormones and action potentials. KNOW HORMONES
- d Embedded in thyroid. Made up of chief cells, which secrete PTH increasing blood calcium levels, stimulates osteoclasts, and promotes calcium reabsorption by kidneys, and Oxyphils whose function is unknown.
