How is the function of the endocrine gland named above affected by an ACTH-secreting pituitary adenoma?
1 pt
1. glucocorticoid secretion is stimulated
2. aldosterone secretion is stimulated
3. teststerone secretion is stimulated
4. insulin secretion is stimulated
5. glucocorticoid secretion is inhibited
6. aldosterone secretion in inhibited
7. insulin secretion is inhibited
Option 1 -Glucocorticoid secreation is Stimulated.
ACTH(Adrenocorticotropic hormone/Corticotropin) is a hormone produced & secreted by the anterior pituitary gland.an ACTH-secreting pituitary adenoma ---There will be large amount of ACTH.
These ACTH Acts on zona fasciculata of the adrenal glands----stimulates secretion of glucocorticoid steroid hormones like Cortisol.
ACTH Have little control over secretion of other hormone secreated from adrenal Gland.
Hormones Secreated from Adrenal Gland include-
1.Catecholamines from Medulla .
2.Androgens from Zona Reticulairs.
3.Glucocorticoids from Zona Fasciculata.
4.Mineralocorticoids from Zona Glomerulosa.
