Which of these hormones is not produced by hypophysis cerebri ?

Options

A. Growth hormone
B. Follicular stimulating hormone
C. Oxytocin
D. Adrenocorticotrophic hormone .

Answer

To solve the question "Which of these hormones is not produced by hypophysis cerebri?", we will analyze the hormones listed in the options and determine their source of production.

### Step-by-Step Solution:

1. **Identify the Hypophysis Cerebri**:
- The term "hypophysis cerebri" refers to the pituitary gland, which is often called the master gland of the endocrine system. It has two main lobes: the anterior lobe (adenohypophysis) and the posterior lobe (neurohypophysis).

2. **List the Hormones in the Options**:
- The hormones provided in the options are:
- Growth Hormone (GH)
- Follicle Stimulating Hormone (FSH)
- Oxytocin
- Adrenocorticotropic Hormone (ACTH)

3. **Determine the Source of Each Hormone**:
- **Growth Hormone (GH)**: Produced by the anterior lobe of the pituitary gland.
- **Follicle Stimulating Hormone (FSH)**: Also produced by the anterior lobe of the pituitary gland.
- **Oxytocin**: This hormone is produced by the hypothalamus and stored and released by the posterior lobe of the pituitary gland.
- **Adrenocorticotropic Hormone (ACTH)**: Produced by the anterior lobe of the pituitary gland.

4. **Identify the Correct Answer**:
- Since both GH, FSH, and ACTH are produced by the pituitary gland, and oxytocin is produced by the hypothalamus, the hormone that is **not produced** by the hypophysis cerebri is **Oxytocin**.

### Conclusion:
The hormone that is not produced by hypophysis cerebri is **Oxytocin**.
