Peripheral Ganglia
...  damage to the Peripheral Nervous System or PNS as well. Receptivity It responds to the synapse of neurons found at splanchnic nerves and the preganglions. The peripheral ganglia involve the inferior mesenteric ganglia, the superior mesenteric ganglia and the cilia. It responds to splanchnic and preganglionic innervations. The splanchnic nerve originates from the preganglionic nerves T4 and T9.  ...

Hepatic Portal System
...  portal vein is one of the largest veins in the area and it carries blood to liver from the spleen and the gastrointestinal tract. The hepatic vein begins where the splenic veins and the superior mesenteric meet. The hepatic vein also drains blood coming from the cystic veins as well as the inferior mesenteric gastric veins. The hepatic vein is one of the most important portal venous systems  ...

Large Intestine
...  appendages - pouches that are stuffed with fats - are attached to the superficial portion of the epiploic appendages. The large intestine is supplied with nerves by the superior and inferior mesenteric plexus. The celiac plexus also does a little innervation. Parasympahetic innervation of the large intestines are done by pelvic splanchnic nerves and the vagus nerves. A person knows that  ...

Small Intestine
...  intestine, though, the small intestine is indeed small. It is the body’s primary digestive organ, in charge of the absorption of nutrients. The small intestine is innervated by the superior mesenteric plexus. Sensory fibers reach the small intestine through the postganglionic sympathetic fibers and the preganglionic parasympathetic fibers. Blood supply to the small intestine is provided  ...

Pancreas
...  while the blood vessels receive the sympathetic innervation. The pancreas get blood supply from the splenic artery, a branch of the celiac artery. The pancreatoduodenal artery (from the superior mesenteric artery) also provides blood flow to the pancreas. Venous drainage happens from the splenic and superior mesenteric veins. They, then, deliver the blood into the hepatic portal  ...
