Morphology and anatomic-surgical segmentation of the spleen of Pecari tajacu Li...

The spleen is a secondary lymphoid organ with importance in clinical surgery. Due this and the lack of data in the literature, the current paper analyzes the organ´s morphology and segmentation in collared peccaries. Twenty animals were used at the Center for the Multiplication of Wild Animals of the Universidade Federal Rural do Semi-Árido, Mossoró RN Brazil. The spleen was removed with the splenic pedicle p...
