Superior Pancreaticoduodenal Artery
The superior pancreaticoduodenal artery is an artery that supplies blood to the duodenum and pancreas. Structure It is a branch of the gastroduodenal artery, which most commonly arises from the common hepatic artery of the celiac trunk, although there are numerous variations of the origin of the gastroduodenal artery. The pancreaticoduodenal artery divides into two branches as it descends, an anterior and posterior branch. These branches then travel around the head of the pancreas and duodenum, eventually joining with the anterior and posterior branches of the inferior pancreaticoduodenal artery. The inferior pancreaticoduodenal artery is a branch of the superior mesenteric artery. These arteries, together with the pancreatic branches of the splenic artery, form connections or anastomoses with one another, allowing blood to perfuse the pancreas and duodenum through multiple channels. Distribution The artery supplies the anterior and posterior sides of the duodenum and hea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gastroduodenal Artery
In anatomy, the gastroduodenal artery is a small blood vessel in the abdomen. It supplies blood directly to the pylorus (distal part of the stomach) and proximal part of the duodenum. It also indirectly supplies the pancreatic head (via the anterior and posterior superior pancreaticoduodenal arteries). Structure The gastroduodenal artery most commonly originates from the common hepatic artery, which is a branch of the celiac trunk. Occasionally, it may arise from the proper hepatic artery or from the right or left hepatic arteries, but these are less common anatomical variations. It first gives rise to the supraduodenal artery, followed by the posterior superior pancreaticoduodenal artery. It terminates in a bifurcation when it splits into the right gastroepiploic artery and the anterior superior pancreaticoduodenal artery ( superior pancreaticoduodenal artery). These branches form functional anastomoses with the anterior and posterior inferior pancreaticoduodenal arteries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Celiac Trunk
The celiac () artery (also spelled coeliac in British English), also known as the celiac trunk or truncus coeliacus, is the first major branch of the abdominal aorta. It is about 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 (the others are the superior and inferior mesenteric arteries). Structure The celiac artery is the first major branch of the descending abdominal aorta, branching at a 90° angle. This occurs just below the crus of the diaphragm. This is around the first lumbar vertebra. There are three main divisions of the celiac artery, and each in turn has its own named branches: The celiac artery may also give rise to the inferior phrenic arteries. Function The celiac artery supplies oxygenated blood to the liver, stomach, abdominal esophagus, spleen, and the superior half of both the duodenum and the pancreas. These structures correspond to the em ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anastomosis
An anastomosis (, : anastomoses) is a connection or opening between two things (especially cavities or passages) that are normally diverging or branching, such as between blood vessels, leaf veins, or streams. Such a connection may be normal (such as the foramen ovale in a fetus' heart) or abnormal (such as the patent foramen ovale in an adult's heart); it may be acquired (such as an arteriovenous fistula) or innate (such as the arteriovenous shunt of a metarteriole); and it may be natural (such as the aforementioned examples) or artificial (such as a surgical anastomosis). The reestablishment of an anastomosis that had become blocked is called a reanastomosis. Anastomoses that are abnormal, whether congenital or acquired, are often called fistulas. The term is used in medicine, biology, mycology, geology, and geography. Etymology Anastomosis: medical or Modern Latin, from Greek ἀναστόμωσις, anastomosis, "outlet, opening", Greek ana- "up, on, upon", stoma "mouth" ...

Splenic Artery
In human anatomy, the splenic artery or lienal artery, an older term, 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. It is known for its tortuous path to the spleen. Structure The splenic artery, the largest branch of the celiac trunk, gives off branches to the stomach and pancreas before reaching the spleen. Note that the branches of the splenic artery do not reach all the way to the lower part of the greater curvature of the stomach. Instead, that region is supplied by the right gastroepiploic artery, a branch of the gastroduodenal artery. The two gastroepiploic arteries anastomose with each other at that point. Relations The splenic artery passes between the layers of the lienorenal ligament. Along its course, it is accompanied by a similarly named vein, the splenic vein, which drains into the hepatic portal vein. Clinical significance Splenic artery aneurysms are rare ...

Pancreatic Branches Of Splenic Artery
The pancreas (plural pancreases, or pancreata) is an organ of the digestive system and endocrine system of vertebrates. In humans, it is located in the abdomen behind the stomach and functions as a gland. The pancreas is a mixed or heterocrine gland, i.e., it has both an endocrine and a digestive exocrine function. Ninety-nine percent of the pancreas is exocrine and 1% is endocrine. As an endocrine gland, it functions mostly to regulate blood sugar levels, secreting the hormones insulin, glucagon, somatostatin and pancreatic polypeptide. As a part of the digestive system, it functions as an exocrine gland secreting pancreatic juice into the duodenum through the pancreatic duct. This juice contains bicarbonate, which neutralizes acid entering the duodenum from the stomach; and digestive enzymes, which break down carbohydrates, proteins and fats in food entering the duodenum from the stomach. Inflammation of the pancreas is known as pancreatitis, with common causes including chro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Superior Mesenteric Artery
In human anatomy, the superior mesenteric artery (SMA) is an artery which arises from the anterior surface of the abdominal aorta, just inferior to the origin of the celiac trunk, and supplies blood to the intestine from the lower part of the duodenum through two-thirds of the transverse colon, as well as the pancreas. Structure Origin In the adult, the SMA arises anterior to inferior border of vertebra L1 ( transpyloric plane). It is usually 1 cm lower than the celiac trunk. Course and relations It initially travels in an anterior/inferior direction, passing behind/under the neck of the pancreas and the splenic vein. Located under this portion of the superior mesenteric artery, between it and the aorta, are the following: * left renal vein - travels between the left kidney and the inferior vena cava (can be compressed between the SMA and the abdominal aorta at this location, leading to nutcracker syndrome). * the third part of the duodenum, a segment of the ...

Inferior Pancreaticoduodenal Artery
The inferior pancreaticoduodenal artery (the IPDA) is a branch of the superior mesenteric artery. It supplies the head of the pancreas, and the ascending and inferior parts of the duodenum. Rarely, it may have an aneurysm. Structure The inferior pancreaticoduodenal artery is a branch of the superior mesenteric artery. This occurs opposite the upper border of the inferior part of the duodenum. As soon as it branches, it divides into Anatomical terms of location, anterior and posterior branches. These run between the head of the pancreas and the lesser curvature of the duodenum. They then join (anastomose) with the anterior and posterior branches of the superior pancreaticoduodenal artery. Variation The inferior pancreaticoduodenal artery may branch from the first intestinal branch of the superior mesenteric artery rather than directly from it. Function The inferior pancreaticoduodenal artery distributes branches to the head of the pancreas and to the ascending and inferior p ...

Anatomical Terms Of Location
Standard anatomical terms of location are used to describe unambiguously the anatomy of humans and other animals. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and axes. The meaning of terms that are used can change depending on whether a vertebrate is a biped or a quadruped, due to the difference in the neuraxis, or if an invertebrate is a non-bilaterian. A non-bilaterian has no anterior or posterior surface for example but can still have a descriptor used such as proximal or distal in relation to a body part that is nearest to, or furthest from its middle. International organisations have determined vocabularies that are often used as standards for subdisciplines of anatomy. For example, '' Termi ...

Duodenum
The duodenum is the first section of the small intestine in most vertebrates, including mammals, reptiles, and birds. In mammals, it may be the principal site for iron absorption. The duodenum precedes the jejunum and ileum and is the shortest part of the small intestine. In humans, the duodenum is a hollow jointed tube about long connecting the stomach to the jejunum, the middle part of the small intestine. It begins with the duodenal bulb, and ends at the duodenojejunal flexure marked by the suspensory muscle of duodenum. The duodenum can be divided into four parts: the first (superior), the second (descending), the third (transverse) and the fourth (ascending) parts. Overview The duodenum is the first section of the small intestine in most higher vertebrates, including mammals, reptiles, and birds. In fish, the divisions of the small intestine are not as clear, and the terms ''anterior intestine'' or ''proximal intestine'' may be used instead of duodenum. In mammals the d ...
