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

Options

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

Answer

To determine how many hormones are secreted from the neurohypophysis (posterior pituitary), we need to analyze the hormones listed in the question: Aldosterone, MSH, Melatonin, Prolactin, ADH, and TSH.

### Step-by-Step Solution:

1. **Understand Neurohypophysis**: The neurohypophysis, also known as the posterior pituitary, is a part of the pituitary gland that primarily stores and releases hormones produced by the hypothalamus.

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

3. **Classify Each Hormone**:
- **Aldosterone**: Secreted by the adrenal glands, not the pituitary.
- **MSH**: Secreted by the adenohypophysis (anterior pituitary).
- **Melatonin**: Secreted by the pineal gland, not the pituitary.
- **Prolactin**: Secreted by the adenohypophysis (anterior pituitary).
- **ADH**: Secreted by the neurohypophysis (posterior pituitary).
- **TSH**: Secreted by the adenohypophysis (anterior pituitary).

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

5. **Conclusion**: Therefore, the total number of hormones secreted from the neurohypophysis is **1**.

### Final Answer:
The answer is **1**.
