Name the layers of adrenal cortex and mention their secretions.

Explanation

1.A pair of adrenal glands are located at the anterior end the kidneys
2. Anatomically the outer regions is the cortex and the inner regions is the medulla.
3. Histologically the adrenal cortex has three distinct zones zona glomerulosa,zona fascuculata and zona reticularis
4. Zona glomerulasa an outer thin layer contitutes about 15% of adrenal cortex and secretes mineralocorticoids.
5. Zona fasciculata. the middle widest layer constitutes about 75% of adrenal cortex and secetes glucocorticoids such as cortisol corticosterone and trace amounts of adrenal androgen and oestrogen
6. Zona reticularis ,an inner zone of adrenal cortex constitue about 10% of adrenal cortex and secretes the adrenal androgen,trace amount of oestrogen and glucocorticoids.
