Which hormone stimulates the secretion of milk in female?
Correct answer: B. Prolactin
- A. LH
- B. Prolactin
- C. Oxytocin
- D. Progesterone
Explanation
Prolactin (lactogenic hormone) is the hormone that stimulates milk secretion in lactating women. Prolactin stimulates mammary glands to produce milk. During pregnancy, prolactin helps in breast enlargement but due to the presence of high levels of progesterone and estrogen, milk secretion does not happen. Once women deliver, both progesterone and estrogen hormones levels drop and prolactin helps in secretion of milk.So the correct answer is "Prolactin".

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
