[Contribution to the study of biliary ducts of the guinea-pig (Cavia porcellus)--the ramus principalis sinister (author's transl)].
The ramus principalis sinister of the biliary duct was studied in 44 adult animals. The ramus principalis sinister, when individualized, appeared free of affluents in 4 preparation (9%). In 91% of the preparations there were always affluents coming from lobi sinistri lateralis and medialis. Together with these branches, other preparations were seen: only from lobi quadrati (59%); ramus processi quadrati and ramus processi papillaris (16%); ramus lobi quadrati draining into ramus lobi sinistri medialis and this into ramus principalis sinistri (9%); ramus principalis dexter (2.3%); ramus sinistri medialis draining into ramus processi papillaris (2.3%) ramus lobi quadrati and ramus lobi sinistri ventralis draining into ramus lobi sinistri and this into ramus principalis sinister (2.3%). The ramus dorsalis lobi sinistri lateralis, papillaris ramus dorsomedialis, ramus ventromedialis lobi sinistri lateralis, ramus lobi sinistri medialis, ramus lobi quadrati, ramus processi papillaris drain, as main collectors, the dorsal, dorsomedial, ventromedial and ventral areas of the lobi sinistri lateralis, lobi sinistri medialis, lobi quadrati and processi papillaris regions respectively.
