Question

Milk secretion is caused by :-

• A. Progesterone
• B. PRH
• C. PRL
• D. Oxytocin

Answer 1

The correct option is D Oxytocin

Oxytocin is a peptide hormone secreted by the posterior pituitary. It is also a neuropeptide, used for inter-neuron communication. This hormone is responsible for secretion or ejection of milk. PRH or prolactin releasing hormone is responsible for the release of Prolactin or PRL, which is a hormone responsible for milk production. Progesterone inhibits lactation during pregnancy.

So, the correct option is 'Oxytocin'.
