adrenergic receptors

Adrenergic receptors are proteins found on the surfaces of cells that respond to hormones like adrenaline (epinephrine) and noradrenaline (norepinephrine). They play a vital role in the body's "fight or flight" response, influencing how we react to stress. There are two main types: alpha and beta receptors, each triggering different effects, such as increasing heart rate, dilating airways, or raising blood pressure. These receptors help regulate various functions in the body, including heart function, blood flow, and the release of energy, making them essential for maintaining balance during physical or emotional challenges.
