Adrenal medulla

The adrenal medulla is the inner part of the adrenal glands, located on top of the kidneys. It functions like a biological emergency response center, releasing hormones called adrenaline (epinephrine) and norepinephrine (noradrenaline) during stressful situations. These hormones increase heart rate, blood flow, and energy levels, preparing the body for "fight or flight" responses. The adrenal medulla is directly connected to the nervous system, allowing it to quickly respond to stress signals. It plays a crucial role in helping the body adapt to sudden challenges, ensuring you’re alert and ready to react.
