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 ...
Large veins that are considered part of the portal venous system are the: . Hepatic portal vein; Splenic vein; Superior mesenteric vein; Inferior mesenteric vein; The superior mesenteric vein and the splenic vein come together to form the actual hepatic portal vein.
Thoracic splanchnic nerves are splanchnic nerves that arise from the sympathetic trunk in the thorax and travel inferiorly to provide sympathetic supply to the abdomen. The nerves contain preganglionic sympathetic fibers and general visceral afferent fibers.
The splanchnic nerves are paired visceral nerves (nerves that contribute to the innervation of the internal organs), carrying fibers of the autonomic nervous system ...
The syndrome involves constriction of the blood vessels of the kidneys and dilation of blood vessels in the splanchnic circulation, which supplies the intestines. [2] The classification of hepatorenal syndrome identifies two categories of kidney failure , termed type 1 and type 2 HRS, which both occur in individuals with either cirrhosis or ...
The renal plexus is a complex network of nerves formed by filaments from the celiac ganglia and plexus, aorticorenal ganglia, lower thoracic splanchnic nerves and first lumbar splanchnic nerve and aortic plexus. [1] The nerves from these sources, fifteen or twenty in number, have a few ganglia developed upon them.
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".
Portal hypertension is defined as increased portal venous pressure, with a hepatic venous pressure gradient greater than 5 mmHg. [3] [4] Normal portal pressure is 1–4 mmHg; clinically insignificant portal hypertension is present at portal pressures 5–9 mmHg; clinically significant portal hypertension is present at portal pressures greater than 10 mmHg.
