BMR and Temperature of body is controlledby which endocrine gland?

Options

A. Adrenal cortex
B. Thymus
C. Thyroid
D. Pituitary

Answer

To determine which endocrine gland controls the Basal Metabolic Rate (BMR) and body temperature, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding BMR**:
- BMR stands for Basal Metabolic Rate, which is the rate at which the body expends energy at rest to maintain vital functions such as breathing, circulation, and cell production.

2. **Identifying the Role of Endocrine Glands**:
- Endocrine glands secrete hormones that regulate various bodily functions, including metabolism and temperature regulation.

3. **Reviewing Key Endocrine Glands**:
- **Adrenal Cortex**: Produces hormones like aldosterone and cortisol, which are involved in stress response and metabolism but do not directly control BMR or body temperature.
- **Thymus Gland**: Primarily involved in immune function, not in regulating BMR or body temperature.
- **Pituitary Gland**: Often referred to as the "master gland," it regulates other endocrine glands but does not directly control BMR or body temperature.

4. **Focusing on the Thyroid Gland**:
- The thyroid gland produces hormones such as thyroxine (T4) and triiodothyronine (T3). These hormones are crucial for regulating BMR and play a significant role in controlling the body's metabolism, including the metabolism of carbohydrates, proteins, and fats.

5. **Conclusion**:
- The endocrine gland that controls BMR and body temperature is the **Thyroid Gland**.

### Final Answer:
The thyroid gland controls the Basal Metabolic Rate (BMR) and body temperature.
