The Arteries of Brain Base in Species of the Cervid Family

Abstract

The aim of the article was to describe the pattern of main arteries at the encephalon base, their connections, and varieties. This study included 106 specimens of the head and cerebral arteries of the following eight species of the cervid family: reindeer, chital, Eld's deer, wapiti, sika deer, fallow deer, Pere David's deer or milu, and Reeve's or Chinese muntjac. The arteries of the animals under study were filled with acetone-dissolved stained vinyl superchloride or stained latex LBS3060. The analysis of the specimens revealed that the vascular system of the species of the studied cervid family was similar to the system described in other ruminant species. A branch diverging from the condylar artery to the rostral epidural rete mirabile is present in all studied cervids, but it can be found also in giraffe and eland. The pattern of the arterial vascularization of the encephalon base, which we observed in our analysis, confirms the morphological similarity between those animals and the correct placement of the cervid family in species taxonomy.
