The adrenal glands regulate very important functions in the body (stress response, blood pressure, fluid balance…). The internal part of the gland (medulla) and the external part (cortex) contain endocrine cells that produce and secrete different hormones. . The Adrenal CORTEX is divided into 3 zones: 1) Zona Glomerulosa (outermost layer): produces mineralocorticoids (the most important one is Aldosterone). Aldosterone regulates blood pressure by controlling sodium and potassium balance in blood. The endocrine cells that release aldosterone are regulated by the renin-angiotensin-aldosterone system (RAAS). This system gets activated when the kidneys detect a drop in blood pressure or low sodium levels. . 2) Zona Fasciculata (middle layer): produces glucocorticoids (the most important one is Cortisol). Cortisol plays a key role in stress response, metabolism regulation, and immune function (cortisol is a potent anti-inflammatory). The endocrine cells that release cortisol are controlled by the hypothalamic-pituitary-adrenal axis. Stress, low blood glucose, and circadian rhythms stimulate this axis. . 3) Zona Reticularis (innermost layer): produces androgens (the most important one is dehydroepiandrosterone or DHEA). DHEA is a pro-hormone that is converted into either testosterone or estrogens, which will contribute to the development of secondary sexual characteristics and influence muscle mass and libido. The endocrine cells that release DHEA are also controlled by the hypothalamic-pituitary-adrenal axis. Stress, low blood glucose, and circadian rhythms stimulate this axis. .

The Adrenal MEDULLA produces catecholamines (epinephrine and norepinephrine). These hormones prepare the body for a "fight or flight" response by increasing heart rate, blood pressure, and blood flow to muscles. Catecholamine release is controlled by the sympathetic nervous system. In response to stress, physical exertion, or emotional excitement, the hypothalamus activates sympathetic nerves that stimulate the adrenal medulla to release epinephrine (adrenaline) and norepinephrine (noradrenaline). . For this video I used a Leica ZOOM 200 stereoscope and an Olympus BX41 microscope at up to 400X magnification. #microscopy #microscope #physiology #adrenalgland #stress #fightorflight #drbioforever
