Consider the following match of hormones and select the incorrect one :

Options

A. Cortisol : Anti - inflammatory , immuno - suppressive and stimulate RBC production
B. Thyroxine : Regulate BMR , maintain water - electrolyte balance and support RBC formation.
C. Adrenaline : prepare body for emergency or '3F' conditions.
D. Calcitonin : Decreases bone calcium level in human body .

Answer

To solve the question regarding the incorrect match of hormones and their functions, we will analyze each hormone and its corresponding function step by step.

### Step 1: Analyze Cortisol
- **Hormone**: Cortisol
- **Function**: Anti-inflammatory, immunosuppressive, and stimulates RBC production.
- **Explanation**: Cortisol is produced in the adrenal cortex and is known for its role in increasing blood glucose levels, anti-inflammatory effects, and immunosuppression. It also stimulates the production of red blood cells (RBCs).
- **Conclusion**: This match is **correct**.

### Step 2: Analyze Thyroxine
- **Hormone**: Thyroxine
- **Function**: Regulates basal metabolic rate (BMR), supports RBC production, and maintains water-electrolyte balance.
- **Explanation**: Thyroxine is produced by the thyroid gland and plays a crucial role in regulating metabolism, supporting RBC production, and maintaining electrolyte balance.
- **Conclusion**: This match is **correct**.

### Step 3: Analyze Adrenaline
- **Hormone**: Adrenaline
- **Function**: Emergency hormone that prepares the body for emergency situations.
- **Explanation**: Adrenaline (also known as epinephrine) is produced in the adrenal medulla and is indeed referred to as the emergency hormone due to its role in the fight-or-flight response.
- **Conclusion**: This match is **correct**.

### Step 4: Analyze Calcitonin
- **Hormone**: Calcitonin
- **Function**: Decreases blood calcium levels and increases bone calcium levels.
- **Explanation**: Calcitonin is produced by the thyroid gland and its primary function is to lower blood calcium levels by inhibiting osteoclast activity (which breaks down bone) and promoting calcium deposition in bones. The statement that it "decreases bone calcium level" is incorrect; it actually helps to increase bone calcium levels.
- **Conclusion**: This match is **incorrect**.

### Final Answer
The incorrect match is **Calcitonin**, as it is stated to decrease bone calcium levels, which is not true.
