General visceral efferent fiber
autonomic nervous system nerve fiber
General visceral efferent fibers (GVE), visceral efferents or autonomic efferents are the efferent nerve fibers of the autonomic nervous system (also known as the visceral efferent nervous system) that provide motor innervation to smooth muscle, cardiac muscle, and glands (contrast with special visceral efferent (SVE) fibers) through postganglionic varicosities.
GVE fibers may be either sympathetic or parasympathetic. Cranial and sacral spinal fibers are parasympathetic GVE fibers, while thoracic and lumbar spinal cord give rise to sympathetic GVE fibers.
The cranial nerves containing GVE fibers include the oculomotor nerve (CN III), the facial nerve (CN VII), the glossopharyngeal nerve (CN IX) and the vagus nerve (CN X).
“General visceral efferent fiber” enters the record as autonomic nervous system nerve fiber. Crown Archives preserves that source wording while asking what General, visceral and efferent can confirm, complicate or overturn.
Why this record matters
“General visceral efferent fiber” is worth following because a concise public description often conceals a longer documentary argument. Here, General, visceral and efferent provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 24, 2024. The linked authority identifier is Q5532402. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
