1. In between the two layers of muscle lies the myenteric plexus ( Auerbach's plexus ). 2. These cells are connected to the smooth muscle via gap junctions and the myenteric plexus . 3. Between the two muscle layers is the myenteric plexus . 4. The nerve bundles of the submucous plexus are finer than those of the myenteric plexus . 5. The myenteric plexus is the major nerve supply to the gastrointestinal tract and controls GI tract motility. 6. Achalasia is a motor disorder of the esophagus characterized by decrease in ganglion cell density in the myenteric plexus . 7. The myenteric plexus originates in the medulla oblongata as a collection of neurons from the ventral part of the brain stem. 8. ICC-MY are present around the myenteric plexus and thought to be pacemaker cells for slow waves in the smooth muscle cells. 9. According to preclinical studies, 30 % of myenteric plexus 'neurons are enteric sensory neurons, thus Auerbach's plexus has also a sensory component. 10. Myenteric plexuses are located between the inner and outer layers of the muscularis externa, while submucosal plexuses are located in the submucosa.
