Question
Which one is milk ejection hormone? a. prolactin b. estrogen c. oxytocin d. relaxin
Correct Answer
Option C is the correct answer.
Detailed Explanation
Oxytocin is the hormone responsible for milk ejection (the 'let-down' reflex). It causes the contraction of myoepithelial cells around the milk-producing alveoli in the mammary glands, forcing milk into the ducts. Prolactin stimulates milk production.
Hint
It's also the 'love hormone' involved in bonding and uterine contractions.
