The dorsal pancreatic artery is a branch of the splenic artery. It anastomoses with the superior pancreaticoduodenal artery and continues as the inferior pancreatic artery on its lower border. [1]
The pancreas 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. 99% 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.
The small intestine or small bowel is an organ in the gastrointestinal tract where most of the absorption of nutrients from food takes place. It lies between the stomach and large intestine, and receives bile and pancreatic juice through the pancreatic duct to aid in digestion. The small intestine is about 18 feet long and folds many times to fit in the abdomen. Although it is longer than the large intestine, it is called the small intestine because it is narrower in width.
The dorsal scapular nerve is a branch of the brachial plexus. It supplies rhomboid major muscle, rhomboid minor muscle, and levator scapulae muscle. It causes the scapula to be moved medially towards the vertebral column. Dorsal scapular nerve syndrome can cause a winged scapula, with pain and limited motion.
In human anatomy, the subclavian arteries are paired major arteries of the upper thorax, below the clavicle. They receive blood from the aortic arch. The left subclavian artery supplies blood to the left arm and the right subclavian artery supplies blood to the right arm, with some branches supplying the head and thorax. On the left side of the body, the subclavian comes directly off the aortic arch, while on the right side it arises from the relatively short brachiocephalic artery when it bifurcates into the subclavian and the right common carotid artery.
In anatomy, the gastroduodenal artery is a small blood vessel in the abdomen. It supplies blood directly to the pylorus and proximal part of the duodenum. It also indirectly supplies the pancreatic head.
In human anatomy, the dorsalis pedis artery is a blood vessel of the lower limb. It arises from the anterior tibial artery, and ends at the first intermetatarsal space. It carries oxygenated blood to the dorsal side of the foot. It is useful for taking a pulse. It is also at risk during anaesthesia of the deep peroneal nerve.
In human anatomy, the greater pancreatic artery, is the largest artery that supplies the pancreas. It arises from the splenic artery.
The transverse cervical artery is an artery in the neck and a branch of the thyrocervical trunk, running at a higher level than the suprascapular artery.
The superior pancreaticoduodenal artery is an artery that supplies blood to the duodenum and pancreas.
The foregut is the anterior part of the alimentary canal, from the mouth to the duodenum at the entrance of the bile duct. Beyond the stomach, the foregut is attached to the abdominal walls by mesentery. The foregut arises from the endoderm, developing from the folding primitive gut, and is developmentally distinct from the midgut and hindgut. Although the term “foregut” is typically used in reference to the anterior section of the primitive gut, components of the adult gut can also be described with this designation. Pain in the epigastric region, just below the intersection of the ribs, typically refers to structures in the adult foregut.
The dorsal nasal artery is an artery of the face. It is one of two terminal branches of the ophthalmic artery. It supplies the lacrimal sac, and sometimes supplies the tip of the nose. It is an important anastomosis with the facial artery through its terminal (angular) branch.
The pancreatic branches or pancreatic arteries are numerous small vessels derived from the splenic artery as it runs behind the upper border of the pancreas, supplying its body and tail.
In anatomy, arterial tree is used to refer to all arteries and/or the branching pattern of the arteries. This article regards the human arterial tree. Starting from the aorta:
The uncinate process is a small part of the pancreas. The uncinate process is the formed prolongation of the angle of junction of the lower and left lateral borders in the head of the pancreas. The word "uncinate" comes from the Latin "uncinatus", meaning "hooked".
Hemosuccus pancreaticus is a rare cause of hemorrhage in the gastrointestinal tract. It is caused by a bleeding source in the pancreas, pancreatic duct, or structures adjacent to the pancreas, such as the splenic artery, that bleed into the pancreatic duct, which is connected with the bowel at the duodenum, the first part of the small intestine. Patients with hemosuccus may develop symptoms of gastrointestinal hemorrhage, such as blood in the stools, maroon stools, or melena, which is a dark, tarry stool caused by digestion of red blood cells. They may also develop abdominal pain. It is associated with pancreatitis, pancreatic cancer and aneurysms of the splenic artery. Hemosuccus may be identified with endoscopy (esophagogastroduodenoscopy), where fresh blood may be seen from the pancreatic duct. Alternatively, angiography may be used to inject the celiac axis to determine the blood vessel that is bleeding. This may also be used to treat hemosuccus, as embolization of the end vessel may terminate the hemorrhage. However, a distal pancreatectomy—surgery to remove of the tail of the pancreas—may be required to stop the hemorrhage.
The minor duodenal papilla is the opening of the accessory pancreatic duct into the descending second section of the duodenum.
The hepatic lymph nodes consist of the following groups:
The spinal cord is a long, thin, tubular structure made up of nervous tissue, which extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column. It encloses the central canal of the spinal cord, which contains cerebrospinal fluid. The brain and spinal cord together make up the central nervous system (CNS). In humans, the spinal cord begins at the occipital bone, passing through the foramen magnum and entering the spinal canal at the beginning of the cervical vertebrae. The spinal cord extends down to between the first and second lumbar vertebrae, where it ends. The enclosing bony vertebral column protects the relatively shorter spinal cord. It is around 45 cm (18 in) long in adult men and around 43 cm (17 in) long in adult women. The diameter of the spinal cord ranges from 13 mm in the cervical and lumbar regions to 6.4 mm in the thoracic area.
