[Structure of the initial portion of sympathetic input in ganglia of the colon and bladder].


PMID 3417030

Abstract

Heterogeneous populations of sympathetic neurons innervating neural plexuses of the colonic intestine and urinary bladder were revealed in cats and guinea pigs. After injection of the marker primuline into the intestinal plexus, labeled neurons were found in the caudal mesenteric sympathetic ganglion, in the ganglia of the solar plexus, in the ganglia of the bordering sympathetic trunk. Sympathetic neurons associated with the innervation of the urinary bladder were only found in the caudal mesenteric sympathetic ganglion. The system of control over the activity of the intestine wall seems to have an intestine-topic module organization, and that of the urinary bladder--a diffuse organization.
