Stomatogastric nervous system
Appearance
The Stomatogastric Nervous System is a commonly studied neural network composed of several ganglia in arthropods that controls the motion of the gut and foregut. The network of neurons acts as a central pattern generator. It is a model system for motor pattern generation because of the small number of cells, which are comparatively large and can be reliably identified. The system is composed of the stomatogastric ganglion, oesophageal ganglion and the paired commissural ganglia.
