Question

How would function of the pituitary be affected if there were a blood clot in the hypothalamic-hypophyseal portal system which reduced blood flow through those vessels?

A) The hypothalamus would produce and secrete less hormone, causing a reduction in hormone released from the posterior pituitarv.
B) The hypothalamus would produce and secrete less hormone, causing a reduction in hormone released from both the anterior and posterior parts of the pituitary.
C) The hypothalamus would produce and secrete less hormone, causing a reduction in hormone released from the
anterior pituitary.
D) The hypothalamus would still produce and secrete the same amount of hormone, but hormone release from the posterior pituitary would be reduced
E) The hypothalamus would still produce and secrete the same or higher levels of hormone, but hormone release from the anterior pituitary would be reduced

Answer 1

A blood clot in the hypothalamic-hypophyseal portal system would reduce blood flow to the anterior pituitary gland. Therefore, the hypothalamus would produce and secrete less hormone, causing a reduction in hormone released from the anterior pituitary. The correct answer is C.

Hope that helps! Good luck! :)
