Prevertebral ganglia and intestinofugal afferent neurones.
Intestinofugal afferent neurones (IFANs) are a unique subset of myenteric ganglion neurones that regulate normal gastrointestinal function. The IFANs relaying mechanosensory information to sympathetic neurones of the prevertebral ganglion (PVG) function as volume detectors. It is possible that mechanosensory information arriving in the PVG via axon collaterals of visceral spinal afferent nerves can be modulated entirely within the PVG itself.
