Verified step by step guidance

Understand the role of the posterior pituitary gland: The posterior pituitary stores and releases hormones produced by the hypothalamus, specifically antidiuretic hormone (ADH) and oxytocin.

Identify the connection between the hypothalamus and the posterior pituitary: The hypothalamus is directly connected to the posterior pituitary via nerve fibers, allowing neural signals to trigger hormone release.

Explore the mechanism of hormone release: Neural signals from the hypothalamus stimulate the posterior pituitary to release ADH and oxytocin into the bloodstream.

Consider the options provided: Evaluate each option based on your understanding of the hypothalamus-pituitary connection. Neural signals from the hypothalamus are the primary trigger for hormone release from the posterior pituitary.

Clarify misconceptions: Hormonal signals from the anterior pituitary, blood glucose levels, and feedback from peripheral endocrine glands do not directly cause the release of ADH and oxytocin from the posterior pituitary.
