Which hormone is responsible for the milk ejection reflex in lactating mothers?

Correct option is B

Oxytocin is the hormone responsible for the milk ejection reflex (let-down reflex) in lactating mothers. It is released by the posterior pituitary gland when a baby suckles, causing contraction of myoepithelial cells in the mammary glands, which pushes milk into the ducts for feeding. Oxytocin also plays a role in uterine contractions during childbirth and bonding between the mother and baby.
Explanation of Each Option:
· Prolactin: Stimulates milk production, but does not control milk ejection.
· Oxytocin: Correct answer; responsible for milk ejection and emotional bonding.
· Estrogen: Helps in breast tissue development, but does not influence lactation directly.
· Progesterone: Maintains pregnancy, but its levels drop after birth to allow lactation.
