Contribution to the study of the extra-hepatic and intra-hepatic bile ducts in horse. Systematization of the ramus principalis dexter, ramus principalis sinister and the ductus choledocus

Abstract

I t was studied, by dissecation, the system of the ramus principalis dexter, ramus principalis sinister and the ductus choledocus in 30 horses. The ductus choledocus is integrated by the ramus principalis dexter and ramus principalis sinister (76.6%), by the ramus principalis dexter, ramus principalis sinister and ramus ventralis lobi dextri (10.0%), by the ramus principalis dexter, ramus principalis sinister and ramus lobi quadrati (6.7%), by the ramus principalis dexter, ramus principalis sinister and ramus dorsalis lobi dextri (6.7%). The system of the ramus principalis dexter is composed, by the ramus ventralis lobi dextri, ramus medius lobi dextri, ramus dorsalis lobi dextri and ramus processi caudati. The system of the ramus principalis sinister is composed by the ramus ventralis lobi sinistri lateralis, ramus lobi sinistri medialis, ramus medius lobi sinistri lateralis, ramus dorsalis lobi sinistri lateralis and ramus lobi quadrati.
