Variation in basal arteries of the brain in polecat (Mustela putorius putorius L.)

Observations carried out on 106 polecat brains showed that the system of basilar arteries of the brain is similar to those in other cornivorous species. The observed variation was manifested in a differentiation connections of the vessels, in occurence of some variations and in asymmetry. Some cases of such variations were hitherto observed only in some ruminants.
