What would be the effect of a blood clot that blocked the veins of the hypothalamo-pituitary portal system in the infundibulum between the hypothalamus and the anterior pituitary gland?
A)Secretion of ACTH will decrease and the adrenal cortex will atrophy
B)The secretion of gonadotropins will decrease and the gonads will hypertrophy
C)Plasma cortisol concentration will decrease, which will cause a decrease in long-loop negative feedback, and so the secretion of ACTH by the pituitary gland will increase
D)Both secretion of ACTH will decrease and the adrenal cortex will atrophy and the secretion of gonadotropins will decrease and the gonads will hypertrophy would occur
E)Both the secretion of gonadotropins will decrease and the gonads will hypertrophy and plasma cortisol concentration will decrease, which will cause a decrease in long-loop negative feedback, and so the secretion of ACTH by the pituitary gland will increase would occur

Quizplus · Accepted Answer

The hypothalamo-pituitary portal system is responsible for transporting releasing hormones from the hypothalamus to the anterior pituitary gland. If the veins of the portal system are blocked, the releasing hormones will not reach the anterior pituitary gland, resulting in decreased secretion of the corresponding hormones. In this case, the blockage will affect the secretion of ACTH, which stimulates the adrenal cortex to secrete cortisol. Without ACTH stimulation, the adrenal cortex will atrophy and plasma cortisol concentration will decrease.
