Thyroid Hormone Diagnose Mind Map The thyroid hormone plays an important role in regulating metabolism. It is responsible for converting food into energy, controlling growth and development, promoting normal nerve function and brain development, maintaining healthy moods, producing red blood cells, and stimulating tissue repair. Creating a mind map can help visualize how thyroid hormones affect each of these processes to gain further insight. As illustrated here in the mind map, diagnosis of a thyroid hormone imbalance requires a physical examination, medical history review, and laboratory tests to assess the levels of hormones like thyroxine (T4) or triiodothyronine (T3). An ultrasound or an imaging test may be conducted if there are signs of nodules in the thyroid gland. The doctor might also perform a thyroid scan to diagnose overactivity or under activity of the gland.
