Which hormone is primarily associated with the body's response to stress?

• A. Adrenaline
• B. Corticosteroids
• C. Cortisol
• D. Insulin

Answer: (B)

Corticosteroids, particularly cortisol, play a crucial role in the body's stress response. When faced with stress, the hypothalamus signals the adrenal glands to release corticosteroids, which prepare the body to handle the challenge. Cortisol, a specific type of corticosteroid, helps to regulate metabolism, immune response, and blood pressure while contributing to the body's ability to manage long-term stress. This hormone increases glucose levels in the bloodstream, enhances energy availability, and modulates various physiological processes that are disrupted during stress, making it essential for dealing with prolonged challenges.

While adrenaline is also involved in the acute stress response, particularly for quick reactions, it is more about immediate, short-term responses instead of sustained stress management. Insulin is primarily responsible for regulating blood glucose levels and does not directly contribute to the stress response. Hence, the association of corticosteroids with managing stress is what makes them pivotal in this context.
