MICROANATOMY

Detailed explanation-1: -Your adrenal glands are endocrine glands located on top of your kidneys. They produce many important hormones, including cortisol, aldosterone and adrenaline. The adrenal hormones help regulate several bodily functions including metabolism, blood pressure and your body’s response to stress.

Detailed explanation-2: -When you think of the adrenal glands (also known as suprarenal glands), stress might come to mind. And rightly so-the two adrenal glands are arguably best known for secreting the hormone adrenaline, which rapidly prepares your body to spring into action in a stressful situation.

Detailed explanation-3: -Adrenaline is a hormone released from the adrenal glands and its major action, together with noradrenaline, is to prepare the body for ‘fight or flight’.

Detailed explanation-4: -During stress, adrenal gland rapidly responds with increased secretion of glucocorticoids (GCs) and catecholamines into circulation, which hormones, in turn, affect metabolism, to provide acutely energy, vasculature to increase blood pressure, and the immune system to prevent it from extensive activation.

Detailed explanation-5: -Adrenaline is released mainly through the activation of nerves connected to the adrenal glands, which trigger the secretion of adrenaline and thus increase the levels of adrenaline in the blood. This process happens relatively quickly, within minutes of the stressful event being encountered.
