(D) The production,secretion,and ejection of milk are complex processes that require the synergistic effects of several hormones,including prolactin,estrogen,progesterone,and oxytocin.$1$. Prolactin: Primarily responsible for the synthesis and production of milk in the mammary alveoli.$2$. Estrogen: Stimulates the growth and differentiation of the milk duct system. High levels of estrogen during pregnancy inhibit actual milk secretion.$3$. Progesterone: Influences the growth and development of the alveoli. Like estrogen,high levels of progesterone inhibit lactation before birth. $A$ drop in progesterone levels after childbirth triggers the onset of copious milk production.$4$. Oxytocin: Essential for the 'milk ejection reflex' (let-down reflex). It causes the contraction of myoepithelial cells surrounding the alveoli,which squeezes the milk into the duct system for ejection.Therefore,all these hormones work together to facilitate the complete process of lactation.
