Biology:Adrenergic nervous system

Short description: Adrenergic transmission

The adrenergic system or adrenergic nervous system 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.

Components

The peripheral adrenergic nervous system is better known as the sympathetic nervous system (SANS), which comprises the autonomic outflow from the thoracic and high lumbar segments of the spinal cord. The parasympathetic nervous system (PANS) is cholinergic, not adrenergic.
