[Electrophysiologic characteristics and functional role of hepatic mechanoreceptors].

In our previous studies, the liver was found to have different specific receptors: mechano(volume)- osmo-, Na+- and K+-sensitive ones. Here, the electrophysiological characteristics of the mechanoreceptors is presented: five types of receptors were distinguished according to their patterns of activity, as well as fast and slowly adapting ones--according to functional characteristics. The hepatic mechanoreceptors seem to participate in systemic regulation of the circulation through the organ (feed--back) and to be an important informative link of the volume--regulating reflex.
