What are catecholamine, glucocorticoids and mineralocorticoids?
Catecholamines are a class of hormones released from adrenal medulla. These are also called emergency hormones or 'Flight or Fight hormones' because they deal with short term response to stress. They increase alertness, heart beat and respiration rate. These are of two types:Epinephrine or adrenalin and norepinephrine or noradrenalin
Glucocorticoids and mineralocorticoids, both classes of hormones are released from adrenal cortex. Both of them produce long term effects.
Glucocorticoids are involved in carbohydrate metabolism. They act on all tissues.Example – Cortisol
Mineralocorticoids regulate the balance of water and electrolytes in our body.They act on renal tubule. Example − Aldosterone
Glucocorticoid - example :Coritsol (most Abundant- helps reuglate chronic stress and ATP production, its stimulated by the ACTH which is released by the anterior pituatary gland) Mineralocorticoid - example : Aldosterone (Regulates sodium concentrations) Catecholamine -example : Epinephrine (adrenaline, release during acute stress, fight or flight reaction.
