What Are the Adrenal Glands

Keep on hearing adrenal glands but not quite grasp what they are and what they do? They’re two glands on top of the kidneys. They’re the stress glands as they respond to physical and mental stress, helping the body adapt to a stressful situation.

They also help us cope. When they’re triggered, they signal the body with their hormones to activate more blood flow to the muscles, increasing the heart rate and blood pressure and heightened mental acuity to prepare us for the impending threat or deadlines.

The glands are made of nerve bundles and they’re set in a rather strategic location where they can access the different organs faster with their neurotransmitters (adrenaline, noradrenaline, catecholamines, and gamma-aminobutyric acid or the GABA).

Being a part of the sympathetic nervous system, they’re responsible for the flight or fight mechanism. The outer part of the glands also produces steroid hormones, namely cortisol, mineralocorticoids, androgens, estrogens, and androstenolone.
