The thyroid is an endocrine gland in the neck. It secretes thyroid hormones, which regulate the body's rate of metabolism, and calcitonin, a protein that assists in calcium balance. The production of thyroid hormones is stimulated by thyrotropin or Thyroid Stimulating Hormone (TSH), which is produced by the pituitary.
Types of thyroid hormones[edit | edit source]
Triiodothyronine and thyroxine are the two main forms of thyroid hormones. Thyroid hormones are partially comprised of iodine and a deficiency of iodine in the diet can lead to decreased production of these hormones. If left uncorrected the thyroid tissue can enlarge, resulting in a pronounced swelling in the neck, called a 'simple goitre.'
