Ecotopically transplanted pituitary secretes following hormone abundantly

Options

A. Oxytocin
B. Vasopressin
C. Prolactin
D. Inhibin.

Answer

To answer the question regarding which hormone is abundantly secreted by ecotopically transplanted pituitary, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks which hormone is secreted abundantly by an ecotopically transplanted pituitary gland. Ecotopic transplantation refers to the placement of the pituitary gland in a location other than its normal anatomical position.

2. **Identify the Hormones Listed**: The options provided are:
- A) Oxytocin
- B) Vasopressin
- C) Prolactin
- D) Inhibin

3. **Analyze Each Hormone**:
- **Oxytocin**: This hormone is produced in the hypothalamus and released from the posterior pituitary. In an ecotopically transplanted pituitary, it is unlikely to be secreted abundantly, as it is not the primary function of the pituitary gland.
- **Vasopressin (ADH)**: Similar to oxytocin, vasopressin is also produced in the hypothalamus and released from the posterior pituitary. It would not be secreted abundantly in this scenario either.
- **Prolactin**: This hormone is secreted by the anterior pituitary. In the case of an ecotopically transplanted pituitary, it is more likely to be secreted abundantly since the anterior pituitary is responsible for producing prolactin.
- **Inhibin**: This hormone is produced in the gonads (testes and ovaries) and is not secreted by the pituitary gland. Therefore, it is not relevant to this question.

4. **Conclusion**: Based on the analysis, the hormone that is abundantly secreted by an ecotopically transplanted pituitary is **Prolactin** (Option C).

### Final Answer:
The ecotopically transplanted pituitary secretes **Prolactin** abundantly.
