"thyrotrophic hormone"的定义和意义

What is "thyrotrophic hormone"?

Thyrotrophic hormone, also known as thyroid-stimulating hormone (TSH), is a hormone secreted by the pituitary gland that plays a crucial role in regulating the function of the thyroid gland. It stimulates the thyroid gland to produce and release thyroid hormones, such as thyroxine (T4) and triiodothyronine (T3), which are essential for maintaining the body's metabolism, growth, and development. TSH levels are controlled by a negative feedback mechanism, where high levels of thyroid hormones inhibit the release of TSH, while low levels stimulate its production. Imbalances in TSH can lead to various thyroid disorders, including hypothyroidism and hyperthyroidism.
