subsystems: the parasympathetic nervous system (PSNS) and sympathetic nervous system (SNS).Relatively recently‚ a third subsystem of neurons that have been named ’non-adrenergic and non-cholinergic’ neurons (because they use nitric oxide as a neurotransmitter) have been described and found to be integral in autonomic function‚ particularly in the gut and the lungs. With regard to function‚ the ANS is usually divided into sensory (afferent) and motor (efferent) subsystems. Within these systems‚ however
