  • Title: [Splanchnic gall bladder mechanoreceptors (author's transl)].
    Author: Crousillat J, Ranieri F.
    Journal: Exp Brain Res; 1980; 40(2):146-53. PubMed ID: 7428871.
    Abstract:
    The aim of the present paper is to study the electrophysiology of splanchnic gall bladder mechanoreceptors. The neurons unitary activity is recorded by means of glass extracellular microelectrodes implanted in the spinal ganglion (T6-L1). Two types of mechanoreceptors have been revealed by punctiform stimulations. 1. Muscular mechanoreceptors a) Slowly-adapting receptors, located in the whole biliary tract, sensitive to distension. b) Rapidly-adapting receptors, located in the gall bladder, recruited during the dynamic phases of stimulation. These receptors are connected with C fibers. II. Peritoneal Mechanoreceptors a) Pacinian corpuscles, located in the mesentery surrounding the biliary tract. b) Slowly-adapting receptors (movement receptors), located in the serosa of the gall bladder and the pericystic and pericholedochal peritoneum. Pacinian corpuscles are connected with A beta fibers, movement receptors with A gamma delta and B fibres.
