The adrenal glands (also known as suprarenal glands) are endocrine glands that produce a variety of hormones including adrenaline and the steroids aldosterone and cortisol. They are found above the kidneys. Each gland has an outer cortex which produces steroid hormones and an inner medulla. The adrenal cortex itself is divided into three zones: zona glomerulosa, the zona fasciculata and the zona reticularis.
The adrenal cortex produces three main types of steroid hormones: mineralocorticoids, glucocorticoids, and androgens. Mineralocorticoids (such as aldosterone) produced in the zona glomerulosa help in the regulation of blood pressure and electrolyte balance. The glucocorticoids cortisol and corticosterone are synthesized in the zona fasciculata; their functions include the regulation of metabolism and immune system suppression. The innermost layer of the cortex, the zona reticularis, produces androgens that are converted to fully functional sex hormones in the gonads and other target organs. The production of steroid hormones is called steroidogenesis, and involves a number of reactions and processes that take place in cortical cells. The medulla produces the catecholamines adrenaline and noradrenaline, which function to produce a rapid response throughout the body in stress situations.
I cannot take all the broken promises you've made
but now I'll never hear your lies
for the last time a dream you've taken cannot be denied
the pain I felt was just a moment in time
...and I know all these things will never change
serenity's mine
the darkness gone, before my eyes I see the burning light
the fire burns inside
I will not fall, to all the words you've spoken I defy
don't have to see the greed in your eyes
...and I know all these things will never change
and you don't feel bad
'for all these things I've kept inside
for all these things that I've denied
you'll never get my soul
for all the times you told a lie
to get your way just like a child
you will not be my demise...'
a cruel misfortune...
a cruel misfortune...
a cruel misfortune...
