The hormone which regulates the basal metabolism in our body is secreted from

Options

A. pituitary
B. thyroid
C. adrenal cortex
D. pancreas

Explanation

### Step-by-Step Solution:

1. **Understanding Basal Metabolism Rate (BMR)**: The Basal Metabolism Rate is the rate at which our body uses energy while at rest to maintain vital functions such as breathing, circulation, and cell production. It is influenced by various factors including hormones.

2. **Identifying the Hormone Responsible for BMR**: The hormone that primarily regulates BMR is thyroxine (T4), which is secreted by the thyroid gland. This hormone plays a crucial role in the metabolism of carbohydrates, fats, and proteins.

3. **Locating the Thyroid Gland**: The thyroid gland is located in the neck, just below the larynx (voice box), and is shaped like a butterfly with two lobes connected by a bridge of tissue called the isthmus.

4. **Understanding Thyroid Hormones**: The thyroid gland produces two main hormones:
- **Triiodothyronine (T3)**, which contains three iodine atoms.
- **Thyroxine (T4)**, which contains four iodine atoms.
Both hormones are derived from the amino acid tyrosine and are essential for regulating metabolism.

5. **Effects of Thyroid Hormones on BMR**:
- An increase in thyroid hormone levels leads to an increase in BMR, resulting in more energy being released from the breakdown of food components.
- Conversely, a deficiency in thyroid hormones results in a decrease in BMR, leading to less energy production.

6. **Conclusion**: Based on the information, the hormone that regulates the basal metabolism in our body is secreted from the thyroid gland.

### Final Answer:
The hormone which regulates the basal metabolism in our body is secreted from the **thyroid gland**.
