Anatomical terms of neuroanatomy

The celiac (or coeliac) branches of vagus nerve are small branches which provide parasympathetic innervation to the celiac plexus.

Celiac plexus A complex network of nerves (a nerve plexus) located in the upper abdomen.

The celiac plexus or coeliac plexus, also known as the solar plexus because of its radiating nerve fibers, is a complex network of nerves located in the abdomen, near where the celiac trunk, superior mesenteric artery, and renal arteries branch from the abdominal aorta. It is behind the stomach and the omental bursa, and in front of the crura of the diaphragm, on the level of the first lumbar vertebra.

Gluten protein composite found in wheat and related grains, including barley and rye

Gluten is a group of proteins, termed prolamins and glutelins, stored with starch in the endosperm of various cereal (grass) grains. It is found in wheat ; barley, rye, and oats as well as products derived from these grains such as breads and malts. Glutens, especially Triticeae glutens, have unique viscoelastic and adhesive properties, which give dough its elasticity, helping it rise and keep its shape and often leaving the final product with a chewy texture. These properties and its relative low cost are the reasons why gluten is so widely demanded by the food industry and for non-food uses.

Coeliac disease long term autoimmune disorder causing intolerance to gluten

Coeliac disease or celiac disease is a long-term autoimmune disorder that primarily affects the small intestine. Classic symptoms include gastrointestinal problems such as chronic diarrhoea, abdominal distention, malabsorption, loss of appetite and among children failure to grow normally. This often begins between six months and two years of age. Non-classic symptoms are more common, especially in people older than two years. There may be mild or absent gastrointestinal symptoms, a wide number of symptoms involving any part of the body or no obvious symptoms. Coeliac disease was first described in childhood; however, it may develop at any age. It is associated with other autoimmune diseases, such as diabetes mellitus type 1 and thyroiditis, among others.

Abdominal aorta

The abdominal aorta is the largest artery in the abdominal cavity. As part of the aorta, it is a direct continuation of the descending aorta.

Celiac artery

The celiac artery, also known as the celiac trunk, or truncus coeliacus, is the first major branch of the abdominal aorta. It is 1.25 cm in length. Branching from the aorta at thoracic vertebra 12 (T12) in humans, it is one of three anterior/ midline branches of the abdominal aorta.

Superior mesenteric artery

In human anatomy, the superior mesenteric artery (SMA) arises from the anterior surface of the abdominal aorta, just inferior to the origin of the celiac trunk, and supplies the intestine from the lower part of the duodenum through two-thirds of the transverse colon, as well as the pancreas.

Splenic artery

The splenic artery is the blood vessel that supplies oxygenated blood to the spleen. It branches from the celiac artery, and follows a course superior to the pancreas.

Common hepatic artery

The common hepatic artery is a short blood vessel that supplies oxygenated blood to the liver, pylorus of the stomach, duodenum, pancreas, and gallbladder.

Left gastric artery

In human anatomy, the left gastric artery arises from the celiac artery and runs along the superior portion of the lesser curvature of the stomach. Branches also supply the lower esophagus. The left gastric artery anastomoses with the right gastric artery, which runs right to left.

Hepatic artery proper

The hepatic artery proper is the artery that supplies the liver and gallbladder. It raises from the common hepatic artery, a branch of the celiac artery.

Inferior phrenic arteries

The inferior phrenic arteries are two small vessels, which supply the diaphragm but present much variety in their origin.

Left gastroepiploic artery

The left gastroepiploic artery, the largest branch of the splenic artery, runs from left to right about a finger’s breadth or more from the greater curvature of the stomach, between the layers of the greater omentum, and anastomoses with the right gastroepiploic.

Abdominal aortic plexus

The abdominal aortic plexus is formed by branches derived, on either side, from the celiac plexus and ganglia, and receives filaments from some of the lumbar ganglia.

Greater omentum

The greater omentum is a large apron-like fold of visceral peritoneum that hangs down from the stomach. It extends from the greater curvature of the stomach, passing in front of the small intestines and doubles back to ascend to the transverse colon before reaching to the posterior abdominal wall. The greater omentum is larger than the lesser omentum, which hangs down from the liver to the lesser curvature. The common anatomical term "epiploic" derives from "epiploon", from the Greek epipleein, meaning to float or sail on, since the greater omentum appears to float on the surface of the intestines. It is the first structure observed when the abdominal cavity is opened anteriorly.

Suprarenal plexus

The suprarenal plexus is formed by branches from the celiac plexus, from the celiac ganglion, and from the phrenic and greater splanchnic nerves, a ganglion being formed at the point of junction with the latter nerve.

Splenic plexus

The splenic plexus is formed by branches from the celiac plexus, the left celiac ganglion, and from the right vagus nerve.

Anterior vagal trunk

The anterior vagal trunk is a branch of the vagus nerve which contributes to the esophageal plexus. It consists primarily of fibers from the left vagus, but also contains a few fibers from the right vagus nerve.

Posterior vagal trunk

The posterior vagal trunk is a branch of the vagus nerve which contributes to the esophageal plexus. It consists primarily of fibers from the right vagus, but also contains a few fibers from the left vagus.

Celiac lymph nodes

The celiac lymph nodes are associated with the branches of the celiac artery. Other lymph nodes in the abdomen are associated with the superior and inferior mesenteric arteries. The celiac lymph nodes are grouped into three sets: the gastric, hepatic and splenic lymph nodes.

Non-celiac gluten sensitivity (NCGS) or gluten sensitivity is defined as "a clinical entity induced by the ingestion of gluten leading to intestinal and/or extraintestinal symptoms that improve once the gluten-containing foodstuff is removed from the diet, and celiac disease and wheat allergy have been excluded".
