Which of the following is mismatched

Options

A. Parathormone - Decreases blood calcium
B. Thyroxine - Increases BMR
C. Growth hormone - Promotes the physical growth of body
D. Insulin - Results in hypoglycemia.

Answer

To determine which of the following options is mismatched, we will analyze each option one by one:

1. **Parathormone**:
- Parathormone, also known as parathyroid hormone (PTH), is secreted by the parathyroid glands.
- Its primary function is to increase the concentration of calcium ions in the blood by stimulating the release of calcium from bones, increasing calcium reabsorption in the kidneys, and promoting the activation of vitamin D to increase intestinal absorption of calcium.
- Therefore, the statement that parathormone decreases blood calcium is **incorrect**. Parathormone actually **increases** blood calcium levels.

2. **Thyroxine**:
- Thyroxine (T4) is a hormone produced by the thyroid gland.
- It plays a crucial role in regulating the basal metabolic rate (BMR), which is the rate at which the body uses energy while at rest.
- The statement about thyroxine increasing BMR is **correct**.

3. **Growth Hormone**:
- Growth hormone (GH) is secreted by the anterior pituitary gland.
- It promotes growth and development in tissues and is essential for physical growth.
- The statement regarding growth hormone promoting physical growth is **correct**.

4. **Insulin**:
- Insulin is an endocrine hormone produced by the beta cells of the pancreas.
- Its primary function is to lower blood glucose levels by facilitating the uptake of glucose into cells and promoting its storage as glycogen.
- The statement that insulin results in hypoglycemia is **correct** because insulin decreases blood glucose levels.

After analyzing all the options, we conclude that the mismatched statement is the first option regarding parathormone, as it incorrectly states that parathormone decreases blood calcium levels, while it actually increases them.

**Final Answer**: The mismatched option is **Parathormone** (it increases blood calcium, not decreases).
