Which of the following is not paired correctly?

Options

A. Myxoedema -swollen facial tissues
B. Insulin -raises blood glucose
C. Parathyroid -tetany
D. Cretinism -mentally retarded

Answer

To determine which of the following pairs is not correctly matched, we will analyze each pair one by one.

1. **Myxoedema - Swollen Facial Tissue**:
- Myxoedema is a condition associated with hypothyroidism, where there is a deficiency of thyroid hormones. One of the symptoms of myxoedema is indeed swollen facial tissues due to the accumulation of mucopolysaccharides.
- **Conclusion**: This pair is correctly matched.

2. **Insulin - Rashes**:
- Insulin is a hormone produced by the pancreas that regulates blood glucose levels. Its primary function is to decrease blood glucose levels, not to cause rashes. In fact, high blood sugar levels can lead to skin issues, but insulin itself does not cause rashes.
- **Conclusion**: This pair is incorrectly matched.

3. **Blood Glucose - Parathyroid**:
- The parathyroid glands secrete parathyroid hormone (PTH), which regulates calcium levels in the blood, not blood glucose levels. Blood glucose is primarily regulated by insulin and glucagon from the pancreas.
- **Conclusion**: This pair is incorrectly matched.

4. **Creatinism - Mentally Retarded**:
- Cretinism is a condition resulting from severe hypothyroidism during infancy or early childhood, leading to stunted growth and mental retardation. This pair is correctly matched as it describes the consequences of untreated congenital hypothyroidism.
- **Conclusion**: This pair is correctly matched.

After analyzing all pairs, we find that the pairs "Insulin - Rashes" and "Blood Glucose - Parathyroid" are not correctly matched. However, since the question asks for one incorrect pairing, the most glaring error is:

**Final Answer**: Insulin - Rashes is not paired correctly.
