Question

Which one of the following pairs correctly matches a hormone with a disease resulting from its deficiency

• A. Luteinising hormone ??Failure of ovulation
• B. Insulin ??Diabetes insipidus
• C. Thyroxine ??Tetany
• D. Parathyroid hormone ??Diabetes mellitus

Answer 1

The Correct Option is A

To determine the correct match between a hormone and a disease resulting from its deficiency, let's analyze each option:

1. Luteinising hormone—Failure of ovulation: Luteinising hormone (LH) is crucial for triggering ovulation in females. A deficiency can indeed result in the failure of ovulation, leading to infertility. This pair is correctly matched.
2. Insulin—Diabetes insipidus: Insulin is a hormone involved in glucose metabolism, and its deficiency leads to diabetes mellitus, not diabetes insipidus. Diabetes insipidus is related to a deficiency of antidiuretic hormone (ADH). Thus, this pair is incorrectly matched.
3. Thyroxine—Tetany: Thyroxine is a hormone produced by the thyroid gland; its deficiency leads to hypothyroidism, such as myxedema in adults and cretinism in children. Tetany is caused by a deficiency of parathyroid hormone, leading to low calcium levels, not by thyroxine deficiency. Therefore, this pair is incorrect.
4. Parathyroid hormone—Diabetes mellitus: Parathyroid hormone (PTH) regulates calcium levels in the blood. Its deficiency causes hypocalcemia leading to tetany, not diabetes mellitus. Diabetes mellitus is related to insulin deficiency. This pair is also incorrectly matched.

The correct answer is the pair "Luteinising hormone—Failure of ovulation," which accurately matches the hormone to the disease resulting from its deficiency.
