Detailed explanation-1: -Your body controls your thyroid hormone (T3 and T4) levels through a complex feedback loop. Your hypothalamus releases thyrotropin-releasing hormone (TRH), which triggers your pituitary gland to release thyroid-stimulating hormone (TSH), which stimulates your thyroid to release T3 and T4.

Detailed explanation-2: -Your pituitary and thyroid glands The pituitary is an endocrine gland located at the base of your brain that controls your endocrine system, including your thyroid. The pituitary affects the thyroid by producing a hormone called thyroid stimulating hormone (TSH).

Detailed explanation-3: -The posterior lobe produces two hormones, vasopressin and oxytocin. These hormones are released when the hypothalamus sends messages to the pituitary gland through nerve cells. Vasopressin is also known as antidiuretic hormone (ADH).

Detailed explanation-4: -Thyroid-stimulating hormone, commonly called TSH and also referred to as thyrotropin, is a hormone that your pituitary gland releases to trigger your thyroid to produce and release its own hormones-thyroxine (T4) and triiodothyronine (T3).
