Describe (HT only) thyroxine as a hormone from the thyroid gland that stimulates basal metabolic rate.

In the subtopic Feedback systems (HT only), this learning objective focuses on describe (HT only) thyroxine as a hormone from the thyroid gland that stimulates basal metabolic rate. Within Hormonal coordination in humans, students should explain this idea in the exact curriculum context rather than as an isolated fact. Approved keywords for this objective include basal metabolic rate, HT only, thyroid, and thyroxine. thyroxine means a hormone produced by the thyroid gland that regulates metabolism and stimulates the basal metabolic rate. Avoid students often confuse thyroxine's role in stimulating the basal metabolic rate with its role in growth and development; instead focus on understanding that thyroxine primarily regulates metabolism, while its effects on growth and development are secondary. Clarify the specific functions of thyroxine in metabolic processes. For exam answers, focus on describing thyroxine's function in stimulating the basal metabolic rate and its origin from the thyroid gland.
