splanchnic nerve
The major nerves supplying sympathetic innervation to the abdomen, including the greater, lesser, and lowest (or smallest) splanchnic nerves that are formed by preganglionic fibers from the spinal cord which pass through the paravertebral ganglia and then to the celiac ganglia and plexuses and the lumbar splanchnic nerves carry fibers which pass through the lumbar paravertebral ganglia to the mesenteric and hypogastric ganglia. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the splanchnic nerve is
The major nerves supplying sympathetic innervation to the abdomen, including the greater, lesser, and lowest (or smallest) splanchnic nerves that are formed by preganglionic fibers from the spinal cord which pass through the paravertebral ganglia and then to the celiac ganglia and plexuses and the lumbar splanchnic nerves carry fibers which pass through the lumbar paravertebral ganglia to the mesenteric and hypogastric ganglia. The atlas records it as a nerve at the organ scale in the human body.
Where the splanchnic nerve is
It sits within the nervous system. Only the system is known. The position shown carries almost no spatial information.
What the splanchnic nerve connects to
The atlas records 8 typed relationships for it, across 5 kinds of connection. part of sympathetic nervous system.
Supply and innervation
This dataset asserts no arterial supply, venous drainage or innervation for the splanchnic nerve. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.
Also called
Also recorded as splanchnic nerves and visceral nerve. Searching any of those names reaches this page.

Questions
Where is the splanchnic nerve?
It sits within the nervous system. Only the system is known. The position shown carries almost no spatial information.
What does the splanchnic nerve connect to?
Part of: sympathetic nervous system.
Is the splanchnic nerve the same in other species?
Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
