Which of the following correctly depicts the control of secretion of glucocorticoids?
A) central nucleus of the amygdala -> activates ACTH secretion from anterior pituitary - > PVN activation -> glucocorticoid secretion from adrenal medulla
B) CRH secretion within the PVN -> activates ACTH release from anterior pituitary -> glucocorticoid secretion from adrenal cortex
C) PVN activation -> CRH secretion in anterior pituitary -> ACTH secretion from anterior pituitary - > glucocorticoid secretion from adrenal cortex
D) ACTH secretion from the PVN -> CRH release from the posterior pituitary -> glucocorticoid secretion from adrenal cortex
E) activation of the central nucleus of the amygdala -> sympathetic activation -> adrenaline release -> glucocorticoid secretion from adrenal cortex
Answer: C
Rationale: The control of secretion of glucocorticoids is: PVN activation -> CRH secretion in anterior pituitary -> ACTH secretion from anterior pituitary - > glucocorticoid secretion from adrenal cortex.
