A client with a history of brain tumors that resulted in partial removal of the pituitary gland years ago expresses concern to the health care provider about whether she will be able to breast-feed her infant. Which physiologic function of the pituitary gland facilitates breast milk production?

Prolactin

Explanation:

Prolactin is an hormone in the body that is synthesized by cells called lactrotrophs which are situated in the pituitary gland of a mammal.

Prolactin helps in the development of the mammary glands as well as in the production of breast milk. Prolactin can also be called luteotropin or luteotropin hormone.

When the nipples of a nursing mother are stimulated either by the sucking action of the baby or any external stimulus, the prolactin hormone is released and breast milk is produced.

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.
