Explanation:

1. Thyroxine, produced by the thyroid gland, is the main hormone that controls the body's metabolic rate.
2. Cortisol is a glucocorticoid that mediates the body's stress response and has anti-inflammatory effects.
3. Insulin signals cells to take up glucose from the bloodstream, thereby lowering blood sugar levels.
4. Adrenaline (epinephrine) is the primary hormone that triggers the "fight or flight" response, increasing heart rate, blood flow, and alertness.
