Editing Sympathetic nervous system (section)

=== Sensation ===
The afferent fibers of the [[autonomic nervous system]], which transmit sensory information from the internal organs of the body back to the central nervous system (or CNS), are not divided into parasympathetic and sympathetic fibers as the efferent fibers are.<ref name="Moore_Agur_2007">{{cite book | vauthors = Moore KL, Agur AM| title=Essential clinical anatomy | publisher=Lippincott Williams & Wilkins | publication-place=Philadelphia, PA | date=2007 | isbn=978-0-7817-6274-8 | oclc=63279568 | pages=34–35}}</ref>  Instead, autonomic sensory information is conducted by [[general visceral afferent fibers]].

General visceral afferent sensations are mostly unconscious visceral motor reflex sensations from hollow organs and glands that are transmitted to the [[Central nervous system|CNS]].  While the unconscious [[reflex arcs]] normally are undetectable, in certain instances they may send [[pain]] sensations to the CNS masked as [[referred pain]]. If the [[peritoneal cavity]] becomes inflamed or if the [[intestine]] is suddenly distended, the body will interpret the afferent pain stimulus as [[Somatic nervous system|somatic]] in origin. This pain is usually non-localized. The pain is also usually referred to [[Dermatome (anatomy)|dermatomes]] that are at the same spinal nerve level as the visceral afferent [[synapse]].{{citation needed|date=June 2013}}<!-- Likely the same source as previously (Moore's Essential Clinical Anatomy) but as I have no access to this source, I cannot check it.-->
