Direct observation of wall motion is not feasible clinically. Highly sophisticated intraluminal sensors and modern recorders offer great accuracy, sensitivity, versatility, and portability.
Two types of sensors are now common, both of which use transducers converters of mechanical to electrical energy: Both of these approaches plexo de meissner y auerbach sensitive and produce high-fidelity recordings of pressure waves within the lumen.
Although the measurement of mechanical activity resulting from contractions is the more commonly performed study, the electromyogram yields additional important information about motor function. Electrical signals can be detected transmucosally using intraluminal electrodes.
High-quality recordings from multiple bipolar electrodes can be made using a technique described by Coremans and associates . Lead wires within the catheter are incorporated into collections of silver powder at opposite edges of holes in the plexo de meissner y auerbach panel C.
The mucosa is aspirated into the hole by applying suction to the lumen of the catheter, creating an electrical contact between the intestine and the electrodes.
This permits bipolar recordings and maintains a constant spatial relationships between the electrodes. Dig Dis Sci 32 Intestinal contractions cause wall motion b Figure Intestinal contractions cause wall motion, creating forces that plexo de meissner y auerbach intraluminal pressure and induce flow.

Dig Dis Sci 33 Most studied intestinal motility patterns: Migrating Motor Complex MMC Figure The most studied intestinal motility patterns are the fasting migrating motor complex equivalent to the migrating myoelectric complex, both of which are abbreviated MMCand the fed or postprandial pattern .
The MMC is made up of three different phases: The activity front begins in the stomach or the proximal jejunum and plexo de meissner y auerbach along the small intestine. When phase III begins in the stomach, it is preceded by an increase in serum motilin concentration.
This complex repeats every 1 to 2 hours and recurs indefinitely until interrupted by a meal. J Anat ; Neuron size and number in the myenteric ple- xus of the newborn and adult rat.

Structure[ edit ] A part of the plexo de meissner y auerbach nervous systemthe myenteric plexus exists between the longitudinal and circular layers of muscularis externa in the gastrointestinal tract.

It is found in the muscles of the esophagus, stomach, and intestine. These properties include presence of glia, interneurons, a small extracellular space, dense synaptic neuropil, isolation from blood vessels, multiple synaptic mechanisms and multiple neurotransmitters.
The myenteric plexus plexo de meissner y auerbach in the medulla oblongata as plexo de meissner y auerbach collection of neurons from the ventral part of the brain stem.
Hirschsprung's disease is a form of functional low bowel obstruction due to failure of caudal migration of neuroblasts within developing bowel — this results in an absence of parasympathetic intrinsic ganglion cells in both Auerbach's and Meissner's plexi.
