The thyroid gland is a butterfly-shaped organ on the front of the neck, beneath the voice box. The thyroid gland regulates various bodily activities by releasing the appropriate amount of thyroid hormones. The thyroid gland produces two hormones known as triiodothyronine, or T3, and thyroxine (T4). The gland also generates calcitonin, which aids bone cells in calcium processing and bone formation. Many thyroid issues necessitate the intervention of a physician or other health care expert.
