Adrenergic nervous system

Adrenergic system or Adrenergic nervous system (ANS) is a group of organs and nerves in which adrenaline (epinephrine) and/or noradrenaline (norepinephrine) act as neurotransmitters. ANS is counted as one of the main neurohormonal systems that regulate cardiovascular function, including smooth muscle tone.[1]


The peripheral adrenergic nervous system consists of three main components:[2]
