What does Thyroid Stimulating Hormone (TSH) control?

• A. The adrenal gland
• B. The pancreas
• C. The thyroid gland
• D. The pituitary gland

Answer: (C)

Thyroid Stimulating Hormone (TSH) specifically regulates the activity of the thyroid gland. It is secreted by the anterior pituitary gland and plays a crucial role in stimulating the thyroid to produce and release thyroid hormones, primarily thyroxine (T4) and triiodothyronine (T3). These hormones are vital for regulating metabolism, growth, and development in the body. When TSH is released into the bloodstream, it binds to receptors on the thyroid gland, triggering it to produce more thyroid hormones. This feedback mechanism is part of the body's endocrine system, ensuring that hormone levels remain balanced for proper physiological function. Understanding the role of TSH is important in the context of bone densitometry as well, since thyroid hormones influence bone metabolism. An imbalance in these hormones can lead to conditions affecting bone density, which is critical for evaluating a patient's bone health.
