The posterior pituitary gland is stimulated to secrete hormones by

Question

Quizplus · Accepted Answer

The posterior pituitary gland is actually an extension of the hypothalamus, and its hormones (oxytocin and vasopressin) are synthesized in the hypothalamus. When these hormones need to be secreted, neurons within the hypothalamus are stimulated and they travel through the infundibulum (the stalk that connects the pituitary gland to the hypothalamus) to the posterior pituitary gland to be released into the bloodstream. The other options (B, C, and D) are not accurate as there are no glandular cells within the posterior pituitary that can be stimulated; the infundibulum simply connects the hypothalamus and the posterior pituitary, it does not have cells for hormone secretion; and neurons within the anterior pituitary do not affect the release of hormones from the posterior pituitary.
