Thyroid hormone regulation primarily occurs through a negative feedback loop involving the hypothalamus, pituitary gland, and thyroid gland. Which of the following best explains how this negative feedback mechanism functions? a. Increased thyroid hormone levels stimulate thyroid releasing hormone (TRH) and thyroid stimulating hormone (TSH) release, enhancing thyroid hormone production. b. Decreased thyroid hormone levels inhibit TRH and TSH release, reducing thyroid hormone production. c. Increased thyroid hormone levels inhibit TRH and TSH release, decreasing thyroid hormone production. d. TRH and TSH levels remain constant regardless of thyroid hormone concentration
