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 ...
In anatomy, a viscus is an internal organ, and viscera is the plural form. Organs consist of different tissues, one or more of which prevail and determine its specific structure and function. Functionally related organs often cooperate to form whole organ systems. Viscera are the soft organs of the body.
The splanchnic nerves are paired visceral nerves (nerves that contribute to the innervation of the internal organs), carrying fibers of the autonomic nervous system ...
In human anatomy, the hepatic portal system or portal venous system is the system of veins comprising the portal vein and its tributaries. The other portal venous system in the body is the hypophyseal portal system. [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 ...
Since antigen levels are usually low, contact in blood circulation would be unlikely. Therefore, T cells need a region where they can go to sample foreign antigens that have entered the body. When an APC, such as a dendritic cell, binds a foreign antigen; it becomes activated and moves into the lymph nodes (sites for antigen sampling by T cells ...
Pulmonary (lung) circulation undergoes hypoxic vasoconstriction, which is a unique mechanism of local regulation in that the blood vessels in this organ react to hypoxemia, or low levels of dissolved oxygen in blood, in the opposite way as the rest of the body. While tissues and organs tend to increase blood flow by vasodilating in response to ...
The lesser splanchnic nerve travels inferiorly, lateral to the greater splanchnic nerve. Its fibers synapse with their postganglionic counterparts in the superior mesenteric ganglion, or in the aorticorenal ganglion. [4] The lesser splanchnic nerve modulates the activity of the enteric nervous system of the midgut. Least splanchnic nerve [1] [2 ...
