Located at the base of the neck on both sides, the butterfly-shaped thyroid gland produces thyroid hormone after receiving chemical signals from the pituitary. The main function of the thyroid hormone is to regulate the metabolism of your cells -- that is, the chemical changes in your cells that cause them to live, grow, and die.
