Adrenomedullary

Adrenomedullary refers to the part of the adrenal gland that produces and secretes catecholamines, such as adrenaline (epinephrine) and noradrenaline (norepinephrine), into the bloodstream in response to stress or other stimuli. The adrenal gland is located on top of each kidney and consists of two parts: the outer adrenal cortex and the inner adrenal medulla. The adrenal cortex primarily produces steroid hormones, while the adrenal medulla produces catecholamines.

The adrenomedullary cells, which are chromaffin cells, are responsible for producing and secreting the catecholamines in response to various stimuli, including stress, exercise, and low blood sugar. Catecholamines have many effects on the body, including increasing heart rate and blood pressure, dilating the airways, and mobilizing energy stores in the body. They are important in the body's "fight or flight" response, which is a physiological response to stress that prepares the body to either confront a threat or flee from it.
