Out of the following hormones , how many are separated from neurohypophysis ?
[Aldosterone, MSH , Melatonin , prolactin ,ADH TSH ]

Options

A. One
B. Two
C. Three
D. Four

Answer

To solve the question regarding how many hormones are secreted from the neurohypophysis, we will analyze each hormone provided in the options.

### Step-by-Step Solution:

1. **Identify the Hormones**: The hormones listed are:
- Aldosterone
- MSH (Melanocyte Stimulating Hormone)
- Melatonin
- Prolactin
- ADH (Antidiuretic Hormone)
- TSH (Thyroid Stimulating Hormone)

2. **Determine the Source of Each Hormone**:
- **Aldosterone**: This hormone is produced by the adrenal cortex, not the neurohypophysis.
- **MSH (Melanocyte Stimulating Hormone)**: This hormone is produced by the adenohypophysis (anterior pituitary), not the neurohypophysis.
- **Melatonin**: This hormone is secreted by the pineal gland, not the neurohypophysis.
- **Prolactin**: This hormone is also produced by the adenohypophysis, not the neurohypophysis.
- **ADH (Antidiuretic Hormone)**: This hormone is produced by the neurohypophysis (posterior pituitary).
- **TSH (Thyroid Stimulating Hormone)**: This hormone is secreted by the adenohypophysis, not the neurohypophysis.

3. **Count the Hormones from Neurohypophysis**:
- From the analysis, the only hormone that is secreted from the neurohypophysis is **ADH**.

4. **Conclusion**: Therefore, out of the listed hormones, only **1 hormone (ADH)** is secreted from the neurohypophysis.

### Final Answer:
**1 hormone (ADH) is secreted from the neurohypophysis.**
