Splanchnic organs - including the stomach, small intestine, large intestine, pancreas, spleen, liver, [2] and may also include the kidney. [3] Splanchnic nerves; Splanchnic mesoderm; Splanchnic circulation – the circulation of the gastrointestinal tract originating at the celiac trunk, the superior mesenteric artery and the inferior ...
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).
The pelvic splanchnic nerves are featured as a key plot point in "Parasites Lost", a 2001 episode of the American animated TV comedy Futurama; when protagonist Philip J. Fry is infected with parasitic worms, the rest of the crew use micro-droids to enter his body with the intention of tickling the pelvic splanchnic ganglion to trigger a convulsive bowel movement that they believe will expel ...
The greater splanchnic nerve travels through the diaphragm and enters the abdominal cavity. Its fibers synapse at the celiac ganglia . [ 4 ] The nerve contributes to the celiac plexus , a network of nerves located in the vicinity of where the celiac trunk branches from the abdominal aorta .
The lumbar splanchnic nerves are splanchnic nerves that arise from the lumbar ganglia (the lumbar part of the sympathetic trunk) [1] and travel to an adjacent plexus near the aorta. They originate from L1 and L2. [citation needed] Together with fibres from the aortic plexus, they form the superior hypogastric plexus. [1]
The sacral sympathetic nerves arise from the sacral part of the sympathetic trunk, emerging anteriorly from the ganglia.They travel to their corresponding side's inferior hypogastric plexus, where the preganglionic nerve fibers synapse with the postganglionic sympathetic neurons, whose fibers ascend to the superior hypogastric plexus, the aortic plexus and the inferior mesenteric plexus, where ...
Splanchnology is the study of the visceral organs, i.e. digestive, urinary, reproductive and respiratory systems. [1] [2] [3] [4]The term derives from the Neo-Latin splanchno-, from the Greek σπλάγχνα, meaning "viscera".
Three spinal nerves in the sacrum (S2–4), commonly referred to as the pelvic splanchnic nerves, also act as parasympathetic nerves. Owing to its location, the parasympathetic system is commonly referred to as having "craniosacral outflow", which stands in contrast to the sympathetic nervous system, which is said to have "thoracolumbar outflow".
