Which would be the effect of a blood clot that blocked the vessels of the hypothalamo-pituitary portal system in the infundibulum between the hypothalamus and the anterior pituitary gland?
A)Secretion of adrenocorticotropic hormone (ACTH)would decrease and the adrenal cortex would atrophy
B)Secretion of gonadotropins will decrease and the gonads will hypertrophy
C)Secretion of corticotropin-releasing hormone (CRH)would decrease
D)Secretion of prolactin would decrease
E)Secretion of follicle-stimulating hormone (FSH)would increase

Quizplus · Accepted Answer

The hypothalamo-pituitary portal system is a network of blood vessels that connects the hypothalamus to the anterior pituitary gland. This system allows the hypothalamus to send releasing hormones to the anterior pituitary gland, which then stimulates the release of hormones from the anterior pituitary gland. A blood clot that blocked the vessels of the hypothalamo-pituitary portal system would prevent the hypothalamus from sending releasing hormones to the anterior pituitary gland, which would then lead to a decrease in the secretion of hormones from the anterior pituitary gland. One of the hormones that would be affected by this is ACTH, which stimulates the release of cortisol from the adrenal cortex. A decrease in ACTH secretion would lead to a decrease in cortisol secretion, which would then lead to atrophy of the adrenal cortex.
