MeSH | D013153 |
Anatomical terms of neuroanatomy |
The splanchnic nerves are paired visceral nerves (nerves that contribute to the innervation of the internal organs), carrying fibers of the autonomic nervous system ( visceral efferent fibers) as well as sensory fibers from the organs ( visceral afferent fibers). All carry sympathetic fibers except for the pelvic splanchnic nerves, which carry parasympathetic fibers.
The term splanchnic nerves can refer to:
Nerve | Pre-/ postsynaptic [2] | autonomic system [2] | Origin [2] | Targets [2] | |
---|---|---|---|---|---|
Cardiopulmonary nerves | Postsynaptic | sympathetic | cervical and upper thoracic ganglia | Thoracic cavity | |
Thoracic splanchnic nerves | generally | Presynaptic | lower thoracic ganglia | Prevertebral ganglia | |
Greater splanchnic nerve | T5– T9 or T10 | Celiac ganglia | |||
Lesser splanchnic nerve | T10– T11 | Superior mesenteric ganglia and Aorticorenal ganglia | |||
Least splanchnic nerve | T12 | Renal plexus | |||
Lumbar splanchnic nerves | L1– 2 | Inferior mesenteric ganglia, ganglia of intermesenteric and hypogastric plexuses | |||
Sacral splanchnic nerves | sacral part of sympathetic trunk | inferior hypogastric plexus and ganglia to the pelvic viscera | |||
Pelvic splanchnic nerves | parasympathetic | S2– S4 | intrinsic ganglia of descending and sigmoid colon, rectum, and inferior hypogastric plexus and ganglia to the pelvic viscera |
