The nerves of the small intestines are derived from the plexuses of parasympathetic nerves around the superior mesenteric artery. From this source, they run to the myenteric plexus (Auerbach's plexus) of nerves and ganglia situated between the circular muscular fibers and the longitudinal muscle fibers of the muscularis externa. From this a secondary plexus, the plexus of the submucosa (Meissner's plexus, submucous plexus, submucosal plexus, plexus submucosus) is derived, and it is formed by branches that have perforated the circular muscular fibers. This plexus lies in the submucous coat of the intestine; it also contains ganglia from which nerve fibers pass to the muscularis mucosae and to the mucous membrane.
They contain Dogiel cells.[1] The nerve bundles of the submucous 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 neurones (EPANs) or intrinsic primary afferent neurones (IPANs)).[2] In Auerbach plexus there are 30% of the enteric sensory neurons.
History
German Georg Meissner was one of the first to further research the nervous system and found Meissners' plexus.

- Enteric neuroplasticity in seawater-adapted European eel (Anguilla anguilla).
- Sorteni C, Clavenzani P, De Giorgio R, Portnoy O, Sirri R, Mordenti O, Di Biase A, Parmeggiani A, Menconi V, Chiocchetti R.Author information Department of Veterinary Medical Science (UNI EN ISO 9001:2008), University of Bologna, Bologna, Italy; Centro interdipartimentale di ricerca sull'alimentazione umana, University of Bologna, Bologna, Italy.AbstractEuropean eels live most of their lives in freshwater until spawning migration to the Sargasso Sea. During seawater adaptation, eels modify their physiology, and their digestive system adapts to the new environment, drinking salt water to compensate for the continuous water loss. In that period, eels stop feeding until spawning. Thus, the eel represents a unique model to understand the adaptive changes of the enteric nervous system (ENS) to modified salinity and starvation. To this purpose, we assessed and compared the enteric neuronal density in the cranial portion of the intestine of freshwater eels (control), lagoon eels captured in brackish water before their migration to the Sargasso Sea (T0), and starved seawater eels hormonally induced to sexual maturity (T18; 18 weeks of starvation and treatment with standardized carp pituitary extract). Furthermore, we analyzed the modification of intestinal neuronal density of hormonally untreated eels during prolonged starvation (10 weeks) in seawater and freshwater. The density of myenteric (MP) and submucosal plexus (SMP) HuC/D-immunoreactive (Hu-IR) neurons was assessed in wholemount preparations and cryosections. The number of MP and SMP HuC/D-IR neurons progressively increased from the freshwater to the salty water habitat (control > T0 > T18; P < 0.05). Compared with freshwater eels, the number of MP and SMP HuC/D-IR neurons significantly increased (P < 0.05) in the intestine of starved untreated salt water eels. In conclusion, high salinity evokes enteric neuroplasticity as indicated by the increasing number of HuC/D-IR MP and SMP neurons, a mechanism likely contributing to maintaining the body homeostasis of this fish in extreme conditions.

- Mathematical modelling of enteric neural motor patterns.
- Chambers JD, Thomas EA, Bornstein JC.Author information Department of Physiology, University of Melbourne, Parkville, Victoria, 3010, Australia.AbstractThe enteric nervous system modulates intestinal behaviours such as motor patterns and secretion. While much is known about different types of neurons and simple reflexes in the intestine, it remains unclear how complex behaviours are generated. Mathematical modelling is an important tool for assisting the understanding of how the neurons and reflexes can be pieced together to generate intestinal behaviours.Models have identified a functional role for slow excitatory post synaptic potentials (EPSPs) by distinguished between fast and slow EPSPs in the ascending excitation reflex. These models also discovered coordinated firing of similarly located neurons as emergent properties of feedforward networks of interneurons in the intestine.A model of the recurrent network of intrinsic sensory neurons identified important control mechanisms to prevent uncontrolled firing due to positive feedback and that the interaction between these control mechanisms and slow EPSPs is necessary for the networks to encode ongoing sensory stimuli. This model also showed that such networks may mediate migrating motor complexes.A network model of VIP neurons in the submucosal plexus found this relatively sparse recurrent network could produce uncontrolled firing under conditions that appear to be related to cholera toxin induced hypersecretion.Abstract modelling of the intestinal fed-state motor patterns has identified how stationary contractions can arise from a polarised network. These models have also helped predict and explained pharmacological evidence for two rhythm generators and the requirement of feedback from contractions in the circular muscle.
