Question

During breastfeeding, as the baby suckles, nerve signals are relayed from the mother’s nipple to the mother’s brain. The brain initiates the mother’s pituitary gland to produce more prolactin (a hormone), which causes more milk to be ejected. This process of breastfeeding is an example of

		acclimatization.
		adaptation.
		positive feedback.
		feedforward regulation.
		negative feedback.

Answer 1

Answer:

Positive feedback

Explanation: A positive feedback mechanism of hormone action is the process in which a certain amount of hormone released by the glands enters into the blood stream and then later further stimulates their release by the respective gland.

One very good example of positive feedback regulation of the hormone is the release of the love hormone; oxytocin from the posterior lobe of the pituitary gland. Once released the hormone facilitates the sucking of the milk from the breats by the child and also at the same time leads to its further release by the gland.
