Question

Which hormone is responsible for stimulating milk synthesis in alveolar cells of the mammary glands?

Options

• Prolactin from the anterior pituitary

• Progesterone from the corpus luteum

• Oxytocin from the posterior pituitary

• Oestrogen from the ovary

Answer 1

Prolactin (LTH), secreted by the anterior pituitary gland, is the primary hormone responsible for stimulating milk synthesis in alveolar cells. It also supports the development of lactiferous tubules during pregnancy, making it essential for lactogenesis—the initiation of milk production.
