The term autonomic nervous system (ANS) refers to groups of motor neurons (ganglia) situated in the head and neck, and in the thorax, abdomen and pelvis, outside the central nervous system (CNS) as shown in Fig. 1. Preganglionic axons, processes of preganglionic neurons in the CNS, innervate the ganglionic neurons. Axonal processes of these neurons (post-ganglionic axons) innervate bodily organs (eyes, salivary glands, heart, stomach, bladder, blood vessels, etc). Complex autonomic ganglia in the walls of the stomach and small intestine are separately classified as the enteric nervous system. Autonomic nerves, together with neuroendocrine pathways and the somatic motor nerves to skeletal muscle comprise the three motor outflows from the CNS.
