Find the odd one out

Options

A. Parathyroid-Tetany
B. Pancreas-Diabetes insipidus
C. Adrenal cortex-cushing's syndrome
D. thyroid -goitre

Answer

To solve the question "Find the odd one out," we need to analyze the given options, which consist of a gland and a related disease. The options are:

1. Parathyroid - Tetanine
2. Pancreas - Diabetes Insipidus
3. Adrenal Cortex - Cushing Syndrome
4. Thyroid - Goiter

Let's break down each option step by step:

### Step 1: Analyze the first option - Parathyroid and Tetanine
- **Parathyroid Gland**: This gland secretes parathormone (PTH), which regulates calcium levels in the blood.
- **Tetanine**: This condition is caused by the hyposecretion (undersecretion) of parathormone, leading to low calcium levels in the blood. This results in increased excitability of nerves and muscles.
- **Conclusion**: This option is correctly matched.

### Step 2: Analyze the second option - Pancreas and Diabetes Insipidus
- **Pancreas**: This gland is primarily responsible for producing insulin and glucagon, which regulate blood sugar levels.
- **Diabetes Insipidus**: This condition is caused by a deficiency of the antidiuretic hormone (ADH), which is secreted by the posterior pituitary gland, not the pancreas.
- **Conclusion**: This option is incorrectly matched.

### Step 3: Analyze the third option - Adrenal Cortex and Cushing Syndrome
- **Adrenal Cortex**: This part of the adrenal gland secretes hormones like cortisol.
- **Cushing Syndrome**: This condition is caused by an excess of cortisol, often due to hypersecretion from the adrenal cortex.
- **Conclusion**: This option is correctly matched.

### Step 4: Analyze the fourth option - Thyroid and Goiter
- **Thyroid Gland**: This gland produces thyroid hormones that regulate metabolism.
- **Goiter**: This condition occurs due to a deficiency of thyroid hormones, leading to an enlargement of the thyroid gland.
- **Conclusion**: This option is correctly matched.

### Final Conclusion:
After analyzing all the options, we find that the odd one out is **Option 2: Pancreas - Diabetes Insipidus**, as it does not correctly match the gland with the disease.
