Adrenal Medulla

The adrenal medulla is the inner part of the adrenal gland, which is located on top of each kidney. It is part of the sympathetic nervous system and is responsible for the production and secretion of hormones involved in the body's response to stress and emergencies.

Function

• Produces and releases hormones such as adrenaline (epinephrine) and noradrenaline (norepinephrine) into the bloodstream.
• These hormones help the body respond to stress by increasing heart rate, dilating airways, and mobilizing energy stores.
• They also play a role in the "fight or flight" response, preparing the body to react to a threatening situation.
