Thyroid hormone synthesis, physiology, pathway explained step-by-step! Animation of thyroid hormone production and regulation by the hypothalamus, anterior pituitary gland, and thyroid gland.
We discuss TRH release from the hypothalamus, TSH release from the anterior pituitary gland, and thyroid hormone synthesis and release from the thyroid gland.
Includes step-by-step walk through of how thyroid hormone is produced within the thyroid gland.
