Potassium iodide can be administered to reduce the absorption of radiation that targets the thyroid. It works by saturating the thyroid with non-radioactive iodine, thereby reducing the uptake of radioactive iodine.
TSH is the thyrotropic hormone or thyroid stimulating hormone which is involved in regulating the growth and activity of the thyroid gland.
TSH stands for thyroid-stimulating hormone. It is produced by the pituitary gland and stimulates the thyroid gland to produce thyroid hormones.
increased sensitivity to sympathetic output
This is referred to as hormonal stimulation and is readily illustrated by the activity of the pituitary gland, which controls the activity of all of the other endocrine glands. The thyroid hormones, e.g, regulate the body's metabolic rate but, in and of itself, the thyroid gland does not how much hormone to produce. This function is reserved for the pituitary gland which secretes thyroid stimulating hormone (TSH) which, in turn, stimulates the thyroid to produce its hormones. As thyroid hormone levels increase they, in turn, "stimulate" the pituitary gland to reduce its TSH stimulation. In actuality, a steady-state, mediated by their respective hormones, exists between the pituitary and the thyroid that maintains a constant level of thyroid hormones and, therefore, a relatively constant metabolic rate.
