After the pituitary gland is stimulated by a Releasing hormone, it will often

The correct answer is: release a hormone that will stimulate an endocrine cell to secrete another hormone.

Explanation:

The pituitary gland is a very important organ in the endocrine system that is part of the Hypothalamus-Pituitary Axis: which means that, after the Hypothalamus secretes a Releasing Hormone, the Pituitary will release a hormone in response to this. This is how many of the peripheral hormones come to be released (for example, the adrenal hormones and the thyroid hormones).

Most of the time, when the peripheral hormones are released, "Negative Feedback" occurs, which means that these hormones will inhibit the pituitary cells that secreted the hormone responsible for their release.
