Which harmone causes ejection of milk from a lactating mammary gland?

Explanation

The oxytocin reflex is also sometimes called the “letdown reflex” or the “milk ejection reflex”.

It is produced more quickly than prolactin.

It makes the milk that is already in the breast flow for the current feed, and helps the baby to get the milk easily.
