Structure of the anal canal and distal rectum in Wistar rats

The conducted research relates to the structure of anal canal and distal rectum of Wistar rats. This structure is of interest in terms of comparative anatomy and as an object of experimental model in pathology. We studies female rats aged 6-10 months, weighing 200-300 g. Light microscopy of specimen...
