The autonomic nervous system is composed of neurons that are not under conscious control, and is comprised of two antagonistic components, the sympathetic and parasympathetic nervous systems. The autonomic nervous system regulates key functions including the activity of the cardiac (heart) muscle, smooth muscles (e.g. of the gut), and glands[GO]. [ ]

external definition

Nervous system including a portion of the central and peripheral systems and presiding over the control and coordination of the vegetative functions of the organism. It innervates smooth and cardiac muscles and glandular tissues and is responsible for many actions which are more or less automatic (e.g. secretion, vasoconstriction etc.). It consists of the sympathetic and parasympathetic nervous systems. [Dorian_AF, Elsevier's_encyclopaedic_dictionary_of_medicine, Part_B:_Anatomy_(1988)_Amsterdam_etc.:_Elsevier][VHOG]

Part of the peripheral nervous system which regulates involuntary functions of the body and consists of the sympathetic and parasympathetic system.[AAO]

homology notes

From comparative analyses of craniate brains, a morphotype of the brain in the earliest craniate stock can be constructed. In marked contrast to cephalochordates, the ancestral craniate morphotype had a plethora of unique features, which included a telencephalon with pallial and subpallial parts, paired olfactory bulbs with substantial projections to most or all of the telencephalic pallium, paired lateral eyes and ears, a lateral line system for both electroreception and mechanoreception, spinal cord dorsal root ganglia, and an autonomic nervous system.[well established][VHOG]
