A patient has decreased growth hormone releasing hormone (GHRH), decreased growth hormone (GH), and increased insulin-like growth factor-1 (IGF-1). At which anatomic site is the problem? Question 12 options:
1) anterior pituitary 2) liver 3) posterior pituitary 4) hypothalamus
ANSWER :
Since, all the endocrine organs or tissues function integratively and respond accodingly to the levels of hormones of hypothalamus, and pituitary gland, hence if an individual has decreased growth hormone releasing hormone (GHRH) from the hypothalamus, then it would necessarily secrete decreased amount of growth hormone (GH) from the anterior lobe of the pituitary gland, which also lead to production of low levels of insulin-like growth factor-1 (IGF-1) in the liver. Hence option (2) is the correct answer choice,
