In human neuroanatomy, the pancreatic plexus is a division of the celiac plexus The celiac plexus, also known as the solar plexus because of its radiating nerve fibers, is a nerve plexus, complex network of nerves located in the abdomen, near where the celiac trunk, superior mesenteric artery, and renal arteries branch fro ...

Pancreas
The pancreas (plural pancreases, or pancreata) is an Organ (anatomy), organ of the Digestion, digestive system and endocrine system of vertebrates. In humans, it is located in the abdominal cavity, 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 lipids, fats in food entering the duodenum from the stomach. Inflammation of the pancreas is kno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Celiac Plexus
The celiac plexus, also known as the solar plexus because of its radiating nerve fibers, is a nerve plexus, 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 crus of the diaphragm, crura of the diaphragm (anatomy), diaphragm, on the level of the first lumbar vertebra. The plexus is formed in part by the greater and lesser splanchnic nerves of both sides, and fibers from the anterior vagal trunk, anterior and posterior vagal trunk, posterior vagal trunks. The celiac plexus proper consists of the celiac ganglia with a network of interconnecting fibers. The aorticorenal ganglia are often considered to be part of the celiac ganglia, and thus, part of the plexus. Structure The celiac plexus includes a number of smaller plexuses: Other plexuses that are derived from the celiac plexus: Terminology The ...

Hepatic Plexus
The hepatic plexus is a sympathetic and parasympathetic nerve plexus that provides innervation to the parenchyma of the liver as well as contributing innervation to some other abdominal structures. Its sympathetic component is derived from the coeliac and superior mesenteric plexuses; its parasympathetic component is derived from the anterior and posterior vagal trunks. Anatomy Afferents Sympathetic The plexus receives post-ganglionic sympathetic afferents from the celiac plexus, and the superior mesenteric plexus. The hepatic plexus is the largest derivative of the celiac plexus. Parasympathetic The plexus receives pre-ganglionic parasymathetic afferents primarily from the anterior vagal trunk, with a lesser contribution from the posterior vagal trunk. The anterior vagal trunk issues one or more hepatic branches of anterior vagal trunk that pass in the superior portion of the lesser omentum to reach the hepatic plexus. Efferents and distribution The plexus is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nerve Plexus
A nerve plexus is a plexus (branching network) of intersecting nerves. A nerve plexus is composed of afferent and efferent fibers that arise from the merging of the anterior rami of spinal nerves and blood vessels. There are five spinal nerve plexuses, except in the thoracic region, as well as other forms of autonomic nervous system, autonomic plexuses, many of which are a part of the enteric nervous system. The nerves that arise from the plexuses have both sensory and motor functions. These functions include muscle contraction, the maintenance of body coordination and control, and the reaction to sensations such as heat, cold, pain, and pressure. There are several plexuses in the body, including: *Spinal plexuses **Cervical plexusserves the head, neck and shoulders **Brachial plexusserves the chest, shoulders, arms and hands **Lumbosacral plexus ***Lumbar plexusserves the back, abdomen, groin, thighs, knees, and calves ****Subsartorial plexusbelow the sartorius muscle of thigh *** ...
