List I | List II | ||
|---|---|---|---|
| A | Exophthalmic goiter | I | Excess secretion of cortisol, moon face & hypergylcemia |
| B | Acromegaly | II | Hypo-secretion of thyroid hormone and stunted growth. |
| C | Cushing’s syndrome | III | Hyper secretion of thyroid hormone & protruding eye balls. |
| D | Cretinism | IV | Excessive secretion of growth hormone. |
To match the conditions with their corresponding descriptions, we need to identify each condition and its characteristics:
Now matching the items in List I with List II, we find:
Therefore, the correct arrangement is A-III, B-IV, C-I, D-II, which aligns with the option given as the correct answer.
Step 1: Understanding each condition:
Exophthalmic Goiter: This condition is caused by an overproduction of thyroid hormone. It is characterized by protruding eyeballs, weight loss, and excessive sweating, which leads to the classification of this condition as III. The overproduction of thyroid hormone leads to hyperthyroidism.
Acromegaly: This condition is caused by excessive secretion of growth hormone, leading to abnormal growth of bones and tissues. The most common result is an enlarged jaw, hands, and feet, which corresponds to IV.
Cushing’s Syndrome: This syndrome is caused by excess cortisol, a hormone produced by the adrenal glands. Symptoms of Cushing's syndrome include a "moon face," hyperglycemia, and high blood pressure. Therefore, this condition matches with I.
Cretinism: Cretinism is a disorder caused by the hypo-secretion of thyroid hormones, leading to stunted growth and developmental delays. This condition matches with II, as it results from insufficient thyroid hormone production.
Step 2: Conclusion:
Thus, the correct match is as follows:
Answer: The correct match is A - III, B - IV, C - I, D - II.
