RESUMO
The afferent vessels of the circulus arteriosus cerebri in the camel were studied quantitatively. It was found that the diameters of the arteries did not differ significantly on the left and right sides. An interesting observation was that the basilar artery contributed to the blood supply of the brain in the camel, in contrast to the situation in other ruminants.

The brain arteries of camels were injected with latex and the rostral epidural rete mirabile, which is situated inside the cavernous sinus at the base of the brain, was studied both grossly and quantitatively. The rostral epidural rete mirabile is formed by the retial branches of the maxillary and external ophthalmic arteries and also the internal carotid artery. When the ratio of the blood supply to the rete was estimated from the diameter of each vessel, it was found that the branches of the maxillary artery carried 76.41%, the branches of the external ophthalmic artery carried 10.26% and the internal carotid artery carried 13.33%.
