General visceral efferent fibers (GVE),visceral efferents orautonomic efferents are theefferent nerve fibers of theautonomic nervous system (also known as thevisceral efferent nervous system) that provide motor innervation tosmooth muscle,cardiac muscle, andglands (contrast withspecial visceral efferent (SVE) fibers) throughpostganglionic varicosities.[1][2]
GVE fibers may be either sympathetic or parasympathetic.[3] Cranial and sacral spinal fibers are parasympathetic GVE fibers, while thoracic and lumbar spinal cord give rise to sympathetic GVE fibers.[4]
Thecranial nerves containing GVE fibers include theoculomotor nerve (CN III), thefacial nerve (CN VII), theglossopharyngeal nerve (CN IX) and thevagus nerve (CN X).[5]
