Question

Oxytocin is involved in

• A. Milk ejection
• B. Parturition
• C. Let down process
• D. All of the above

Answer 1

The correct option is D All of the above

Oxytocin is released by posterior pituitary during parturition in response to foetus ejection reflex. It stimulates strong uterine muscle contraction forcing the fetus downwards during parturition. Oxytocin helps to initiate release of milk by mammary gland after child birth. The more a baby suckles, the more oxytocin is released leading to milk let down. Thus, the correct answer is D.
