Which of these hormones is not produced by hypothesis cerebri ?

Options

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

Answer

To determine which hormone is not produced by the hypophysis cerebri (pituitary gland), we need to analyze the hormones listed in the question: Growth Hormone, Follicle Stimulating Hormone, Oxytocin, and Adrenocorticotropic Hormone.

### Step-by-Step Solution:

1. **Understand the Structure of the Pituitary Gland**: The pituitary gland, also known as the hypophysis cerebri, consists of two main parts: the anterior pituitary and the posterior pituitary.

2. **Identify Hormones Produced by the Anterior Pituitary**:
- The anterior pituitary produces several hormones, including:
- Growth Hormone (GH)
- Follicle Stimulating Hormone (FSH)
- Luteinizing Hormone (LH)
- Adrenocorticotropic Hormone (ACTH)
- Prolactin
- Melanocyte Stimulating Hormone (MSH)

3. **Identify Hormones Produced by the Posterior Pituitary**:
- The posterior pituitary primarily stores and releases hormones produced by the hypothalamus, which include:
- Oxytocin
- Antidiuretic Hormone (ADH, also known as Vasopressin)

4. **Determine the Source of Each Hormone**:
- **Growth Hormone**: Produced by the anterior pituitary.
- **Follicle Stimulating Hormone**: Produced by the anterior pituitary.
- **Oxytocin**: Produced by the hypothalamus, stored and released by the posterior pituitary.
- **Adrenocorticotropic Hormone**: Produced by the anterior pituitary.

5. **Conclusion**: Among the options provided, Oxytocin is the hormone that is not produced by the hypophysis cerebri (pituitary gland) but is instead produced by the hypothalamus.

### Final Answer:
**Oxytocin** is not produced by the hypophysis cerebri.
