What hormones are produced by the thyroid gland?

The thyroid gland plays a vital role in the body by producing hormones that are crucial for regulating metabolism, maintaining body temperature, and supporting bone growth. The primary hormones secreted by the thyroid gland include thyroxine (T4) and triiodothyronine (T3).

These hormones are essential for metabolic processes as they influence how the body uses energy and how cells convert nutrients into energy. They also contribute to thermoregulation, helping to maintain an appropriate body temperature. Additionally, thyroid hormones are involved in promoting proper bone development and growth, underscoring their importance in overall physiological function.

In contrast, hormones that regulate mood are primarily produced by other glands such as the adrenal glands and the pituitary gland. Hormones that induce sleep are related more to the functions of the pineal gland, which secretes melatonin. Similarly, hormones that stimulate adrenal function, like adrenocorticotropic hormone (ACTH), are secreted by the pituitary gland and do not originate from the thyroid. Therefore, the selection of the option related to metabolism, body heat regulation, and bone growth accurately reflects the main functions of hormones produced by the thyroid gland.
