The correct Answer is:
To solve the question regarding the functions of oxytocin in human adult females, we will analyze each statement provided in the options. ### Step-by-Step Solution: 1. **Understanding Oxytocin**: - Oxytocin is a hormone produced in the hypothalamus and released by the posterior pituitary gland. It plays a crucial role in various reproductive processes. 2. **Evaluating Each Option**: - **Option i: Stimulates pituitary to secrete vasopressin**: - This statement is incorrect. Oxytocin and vasopressin are both secreted by the posterior pituitary, but oxytocin does not stimulate the secretion of vasopressin. - **Option ii: Strong uterine contractions during parturition**: - This statement is correct. Oxytocin is known to stimulate strong uterine contractions during childbirth (parturition), facilitating labor. - **Option iii: Is secreted by anterior pituitary**: - This statement is incorrect. Oxytocin is secreted by the posterior pituitary, not the anterior pituitary. - **Option iv: Stimulates growth of mammary glands**: - This statement is also incorrect. While oxytocin plays a role in lactation (milk ejection), it does not stimulate the growth of mammary glands. The development of mammary glands is primarily influenced by other hormones, such as estrogen and progesterone. 3. **Conclusion**: - Based on the evaluation, the only correct statement regarding oxytocin in human adult females is **Option ii**, which states that it stimulates strong uterine contractions during parturition. ### Final Answer: - The correct option is **ii. strong uterine contractions during parturition**.
