The correct Answer is:
To solve the question regarding the functions of corticosteroid hormones, we need to evaluate each of the given statements (I, II, III, IV) based on what we know about corticosteroids. ### Step-by-Step Solution: 1. **Understanding Corticosteroids**: - Corticosteroids are hormones produced by the adrenal cortex. They are classified into two main types: glucocorticoids and mineralocorticoids. 2. **Analyzing Statement I**: - "Depresses the immune response": This is true. Glucocorticoids, such as cortisol, are known to suppress the immune system and reduce inflammation. 3. **Analyzing Statement II**: - "Stimulates sexual and reproductive activity": This is not primarily a function of corticosteroids. While some corticosteroids may have minor effects on reproductive functions, they are not the main hormones responsible for stimulating sexual and reproductive activity. This function is more associated with sex hormones like androgens and estrogens. 4. **Analyzing Statement III**: - "Influences blood glucose concentration": This is true. Glucocorticoids, particularly cortisol, play a significant role in increasing blood glucose levels by promoting gluconeogenesis in the liver. 5. **Analyzing Statement IV**: - "Influences ionic and osmotic concentration of blood": This is also true. Mineralocorticoids, such as aldosterone, regulate sodium and potassium levels in the blood, thus influencing osmotic balance and blood pressure. ### Conclusion: Based on the analysis: - **True Statements**: I, III, and IV. - **False Statement**: II. Thus, the best description of the functions of corticosteroid hormones includes statements I, III, and IV. ### Final Answer: The correct functions of corticosteroid hormones are: - I. Depresses the immune response - III. Influences blood glucose concentration - IV. Influences ionic and osmotic concentration of blood
