Which one of the following function is not related to hormones of adrenal cortex of adrenal gland?
Options:
Answer:
Solution:
The adrenal cortex is mesodermal in origin. The cortex consists of fatty, cholesterol-rich cells. These cells distinguish the cortex into three zones or regions.
(i) Zona glomerulosa: It is the outer part of the cortex (15% of the gland), which consists of small polyhedral cells. It secrets mineralocorticoids e.g., Aldosterone. Mineralocorticoids (aldosterone) hormone regulate the balance of water and electrolytes.
(ii) Zona fasciculata: It is the middle part of the cortex (50% of the gland). Which consists of large polyhedral cells. This part secrets glucocorticoid e.g., cortisone, corticosterone. Glucocorticoid hormone stimulate RBCs production and suppresses immune response/system.
(iii) Zona Reticularis: It is the inner part of the cortex (7% of the gland). In which the parallel cell cords of the zona fasciculata branched to form a loose anastomosing network. It secrets sex hormones.
Adrenal medullary/adrenaline hormones maintain emergency or 3 F conditions
