Terminal plexuses ( TPL ; Swanson & Bota, 2010 ) : A topographic division of autonomic nerves (Langley, 1898) that form more or less discrete anastomoses of small white matter tracts (bundles) in or near the walls of innervated viscera. They are characterized by parasympathetic ganglion cells that only sometimes condense into macroscopically obvious terminal ganglia (Gaskell, 1886). The distinction between terminal plexuses and prevertebral plexuses is clearly illustrated by Ranson (1920, Fig. 250) and Williams & Warwick (1980, Fig. 7-224, and pp. 1122-1137).
