The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Neurohypophysis**: The neurohypophysis, also known as the posterior pituitary, is one of the two parts of the pituitary gland. It plays a crucial role in the release of certain hormones. 2. **Identifying the Hormones Released**: The neurohypophysis primarily stores and releases two important hormones: - **Oxytocin**: This hormone is involved in various functions, including stimulating contractions of smooth muscles, particularly during childbirth and lactation. - **Vasopressin (also known as Antidiuretic Hormone, ADH)**: This hormone is responsible for regulating water absorption in the kidneys, thus playing a critical role in maintaining body fluid balance. 3. **Clarifying the Incorrect Options**: The question also mentions prolactin. It is important to note that prolactin is not released from the neurohypophysis; instead, it is produced and released from the anterior pituitary (adenohypophysis). Therefore, any option that includes prolactin is incorrect. 4. **Conclusion**: The correct answer to the question regarding which hormones are released from the neurohypophysis is **vasopressin and oxytocin**. 5. **Final Answer**: The neurohypophysis releases vasopressin and oxytocin. ---
