Solution
Adrenal gland:
These endocrine glands are located above each kidney.
These glands perform various functions inside the human body by releasing hormones.
The adrenal gland consists of two parts:
Adrenal medulla: The inner part of the adrenal gland is located inside the center of the cortex. It secretes epinephrine and norepinephrine hormones.
Adrenal cortex: This is the outer part of the adrenal gland that secretes steroid hormones including aldosterone (zona glomerulosa), cortisol (zona fasciculata), and androgens (zona reticularis).
Thus, the adrenal cortex secretes two major classes of hormones:
Mineralocorticoids: For example aldosterone for mineral balance in the body.
Glucocorticoids: For example cortisol for anti-inflammatory and stress metabolism control.
