Which of the following hormone is correctly matched with it's source & function?

Options

A. Vasopressin -Anterior pituitary-Induces reabsorption of water in nephron
B. Oxytocin -Anterior pituitary-Contraction in uterine muscles during birth (parturation)
C. Thymocin -Thymus-Helps in differentiation of T- Lymphocyte
D. Glucagon -Pancreatic -cells -Induces the uptake & utilization of glucose inside cells.

Answer

To determine which hormone is correctly matched with its source and function, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Identify the Hormones and Their Sources**:
- **Vasopressin (ADH)**: This hormone is produced in the hypothalamus and stored and released from the posterior pituitary gland (neurohypophysis).
- **Oxytocin**: Similar to vasopressin, oxytocin is also produced in the hypothalamus and released from the posterior pituitary gland.

2. **Check the Functions of the Hormones**:
- **Vasopressin (ADH)**: Its primary function is to regulate water balance in the body by increasing water reabsorption in the kidneys.
- **Oxytocin**: This hormone is involved in childbirth and lactation, stimulating uterine contractions and milk ejection.

3. **Analyze the Third Option - Thymosine**:
- **Thymosine**: This hormone is produced in the thymus gland.
- **Function of Thymosine**: It is responsible for the differentiation of T-lymphocytes (a type of white blood cell) and plays a role in the immune response.

4. **Evaluate the Options**:
- The first option (Vasopressin) is incorrectly matched because it states that it comes from the anterior pituitary, which is incorrect.
- The second option (Oxytocin) is also incorrectly matched for the same reason as vasopressin.
- The third option (Thymosine) is correctly matched with its source (thymus gland) and its function (differentiation of T-lymphocytes).

5. **Conclusion**:
- The correct answer is the third option, which matches thymosine with its source (thymus gland) and its function (differentiation of T-lymphocytes).

### Final Answer:
The hormone that is correctly matched with its source and function is **Thymosine** from the **Thymus gland**, responsible for the differentiation of T-lymphocytes.
