The plexus includes sensory receptors, such as chemoreceptors and mechanoreceptors, that are used to provide sensory input to the interneurons in the enteric nervous system. The plexus is the parasympathetic nucleus of origin for the vagus nerve and communicates with the medulla oblongata through both the anterior and posterior vagal nerves.
The fibers are carried by both the anterior and posterior vagal nerves. The myenteric plexus is the major nerve supply to the gastrointestinal tract and controls GI tract motility. [1] According to preclinical studies, 30% of myenteric plexus' neurons are enteric sensory neurons, thus Auerbach's plexus has also a sensory component. [2] [3]
A nerve plexus is a plexus ... many of which are a part of the enteric nervous system. The nerves that arise from the plexuses have both sensory and motor functions ...
The myenteric plexus extends the full length of the gut, situated between the circular and longitudinal muscle layers. Beyond its primary motor and secretomotor functions, the myenteric plexus exhibits projections to submucosal ganglia and enteric ganglia in the pancreas and gallbladder, showcasing the interconnectivity within the ENS.
The plexus is formed in part by the greater and lesser splanchnic nerves of both sides, and fibers from the anterior and 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 ...
The nerve contributes to the celiac plexus, a network of nerves located in the vicinity of where the celiac trunk branches from the abdominal aorta. The greater splanchnic nerve modulates the activity of the enteric nervous system of the foregut. It stimulates contraction of the splanchnic vasculature, increasing blood pressure. [5]
The nerve bundles of the submucosal plexus are finer than those of the myenteric plexus. Its function is to innervate cells in the epithelial layer and the smooth muscle of the muscularis mucosae. 14% of submucosal plexus neurons are sensory neurons – Dogiel type II, also known as enteric primary afferent neurons or intrinsic primary afferent ...
Renal plexus: Lumbar splanchnic nerves: L1–2: Inferior mesenteric ganglia, ganglia of intermesenteric and hypogastric plexuses: Sacral splanchnic nerves: sacral part of sympathetic trunk: inferior hypogastric plexus and ganglia to the pelvic viscera: Pelvic splanchnic nerves: parasympathetic: S2–S4
