what controls the thyroid gland
The amount of thyroid hormone made by your thyroid gland is adjusted by a gland in the brain called the pituitary. Another part of your brain, the hypothalamus, helps the pituitary. The hypothalamus sends information to the pituitary gland, the pituitary in turn controls the thyroid gland.t does this by releasing more thyroid-stimulating hormone (or TSH), which signals your thyroid to make more thyroid hormone. Your thyroid gland then makes and releases the hormone directly into your bloodstream. Your pituitary gland then senses that there is just the right amount of thyroid hormone in your body.
