Thyroid anatomy. Computer artwork of the thyroid glands (pink) of the neck, shown in relation to the body's bones and throat structures (white). The head is at top, with the clavicles and upper ribs across bottom. These joined paired glands are found in the neck, enclosing the trachea below the larynx. They are part of the endocrine system, releasing thyroid hormones into the bloodstream to regulate the rate of the body's metabolism and growth.
