The thyroid is one of the main endocrine glands in the body. This gland is found in the neck inferior to (below) the thyroid cartilage (also known as the Adam's apple in men) and at around the same level as the cricoid cartilage. The thyroid controls how rapidly the body burns energy, makes proteins, and how sensitive the body should be to other hormones.
The thyroid participates in these processes by producing thyroid hormones, mainly thyroxine (T4) and triiodothyronine (T3). These hormones control the rate of metabolism and affect the growth and rate of function of many other systems in the body. Iodine is an essential component of both T3 and T4. The thyroid also produces the hormone calcitonin, which plays a main role in calcium homeostasis.
The thyroid is prohibited by the hypothalamus and pituitary. The gland gets its name from the Greek word for "shield", after the form of the related thyroid cartilage. Hyperthyroidism (overactive thyroid) and hypothyroidism (underactive thyroid) are the most general problems of the thyroid gland.
