Which hormone is produced by the thyroid gland?

The thyroid gland produces the hormone thyroxin, which is also known as T4. This hormone plays a crucial role in regulating the body's metabolism, energy generation, and overall growth and development. Thyroxin influences various physiological processes, including how the body uses carbohydrates and fats and the rate at which it consumes energy.

It is important to note that other hormones listed in the options are produced by different glands. Insulin is produced by the pancreas and regulates blood sugar levels. Cortisol is a hormone produced by the adrenal glands, primarily involved in stress response and metabolism regulation. Adrenaline, also produced by the adrenal glands, is responsible for the body's fight-or-flight response. Understanding the specific hormones produced by different glands aids in grasping human physiology and the endocrine system's functioning.
