Which of the following hormones does not have a particular target organ in the body?

Options

A. Growth hormone
B. TSH
C. Oxytocin
D. FSH

Explanation

To determine which hormone does not have a particular target organ in the body, we will analyze each of the provided options:

1. **Growth Hormone (GH)**:
- GH is secreted by the anterior pituitary gland.
- It has a widespread effect on the body, stimulating growth in various cells and promoting protein metabolism and calcium absorption.
- **Conclusion**: GH does not target a specific organ; it affects multiple tissues throughout the body.

2. **Thyroid Stimulating Hormone (TSH)**:
- TSH is also secreted by the anterior pituitary gland.
- Its primary function is to stimulate the thyroid gland to release hormones T3 and T4.
- **Conclusion**: TSH has a specific target organ, which is the thyroid gland.

3. **Oxytocin**:
- Oxytocin is produced in the hypothalamus and released by the posterior pituitary gland.
- It primarily acts on the mammary glands to facilitate lactation and also affects the uterus during childbirth.
- **Conclusion**: Oxytocin has a specific target organ, which is the mammary glands and uterus.

4. **Follicular Stimulating Hormone (FSH)**:
- FSH is secreted by the anterior pituitary gland.
- It acts on the ovaries in females to regulate the menstrual cycle and stimulate the growth of ovarian follicles.
- **Conclusion**: FSH has a specific target organ, which is the ovaries.

**Final Answer**: The hormone that does not have a particular target organ in the body is **Growth Hormone (GH)**.
