Abstract

The aim of this study was to analyse and compare the cerebral arterial circle, its anastomoses, its branches and the manner of blood supply in 20 individuals of the Camelidae family. The Camelidae family was represented by Camelus bactrianus (n = 8), Camelus dromedarius (n = 2), Lama guanicoe (n = 5) and Lama glama (n = 5). We performed the analyses on post-mortem material obtained from Polish zoological gardens. Arteries of the heads were injected with pigmented acetone solution of vinyl superchloride. Arteries of the brain base in Camelus and Lama species are similar. In contrast, the pattern of brain base arteries in Camelidae differs from the patterns described in other species of the Artiodactyla order. Specific traits of the base brain arterial pattern in Camelidae may prove useful as a taxonomic exponent of the animals within the Artiodactyla order.
