“…In two brains (5.3%) the opened arterial circle of the brain was observed in the rostral part. A similar phenomenon was described by Barone (), Brudnicki et al (), and De Souza and Campos () in rabbit.…”

“…Brudnicki et al () and De Souza and Campos (), describing the brain base arteries in New Zealand rabbits, suggest that caudal cerebral arteries were created as a result of anastomosis of the caudal communicating artery with the terminal branch of the basilar artery. The construction and method of departure of caudal cerebral arteries in hare confirm this statement.…”

Research into course and variability of brain arteries in hare were performed on 38 adult hares of both sexes (males 23 and females 15). The arteries were filled with a synthetic latex at a constant pressure introduced with a medical syringe to the left ventricle. The source of blood supply to the brain was internal carotid arteries, whose branches formed an arterial circle of the brain, vertebral arteries, and basilar artery as the result of its anastomosis. Variability focused on a method of departure of middle cerebral arteries, which were multiple vessels in 39.5% of cases and rostral cerebellar arteries. Caudal communicating arteries in hare comprised bilateral anastomosis of internal carotid arteries and final branches of the basilar artery. It stabilized the steady flow of blood to all parts of the brain. Caudal cerebral arteries comprised final branches of the basilar artery. The largest capacity of all the arteries of the brain was observed in the main trunk of the basilar artery. The capacity of these vessels was 4.53 mm 3 on average. The factor of capacity of cerebral arteries in relation to weight of the brain reaches a high value in hare.

“…In these two species it was open in most cases, whereas in the capybara (Reckziegel et al 2001), the arterial circle of the brain was open in only a few cases. An open arterial circle of the brain was described by de Souza and Campos (2013) in 6.7% of rabbits and by Brudnicki et al (2012) in 5.26% of the cases studied.…”

“…Brudnicki et al (2012) and de Souza and Campos (2013) identified multiple middle cerebral arteries in 36.5% of wild rabbits and 20% of New Zealand rabbits, respectively. The arterial circle of the brain, open from the rostral side, was described in the degu in 48% of individuals, and was also encountered in other species.…”

The brain arteries derived from 50 adult degu individuals of both sexes were injected with synthetic latex introduced with a syringe into the left ventricle of the heart under constant pressure. After fixation in 5% formalin and brain preparation, it was found that the sources of the brain's supply of blood are vertebral arteries and the basilar artery formed as a result of their anastomosis. The basilar artery gave rise to caudal cerebellar arteries and then divided into two branches which formed the arterial circle of the brain. The internal carotid arteries in degus, except for one case, were heavily reduced and did not play an important role in the blood supply to the brain. The arterial circle of the brain in 48% of the cases was open from the rostral side. Variation was identified in the anatomy and the pattern of the arteries of the base of the brain in the degu which involved an asymmetry of the descent of caudal cerebellar arteries (6.0%), rostral cerebellar arteries (8%) as well as middle cerebral arteries (12%). In 6% of the individuals double middle cerebral arteries were found. In one out of 50 cases there was observed a reduction in the left vertebral artery and the appearance of the internal carotid artery on the same side. In that case the left part of the arterial circle of the brain was supplied with blood by an internal carotid artery, which was present only in that animal.

“…In the rabbit (Oryctolagus cuniculus), Davis (1929) defined the ophthalmic artery as a very thin internal branch of the carotid artery. Brudnicki et al (2012) and De Souza and Campos (2013) described the internal ophthalmic artery in the wild rabbit (Oryctolagus cuniculus) to originate from the vessels of the cerebral arterial circle at the height of the rostral choroidal artery and as the lateral branches of rostral and caudal branches of the internal carotid artery. In the lesser mole rat (Spalax leucodon), the internal ophthalmic artery is a branch of the internal carotid artery ).…”

ABSTRACT:The aim of this investigation was the analysis of the variability within the internal and external ophthalmic artery in the chinchilla (Chinchilla laniger, Molina). The head vasculature of 65 individuals was analysed, with particular emphasis on the internal ophthalmic artery originating from the central and rostral part of the cerebral arterial circle. Head blood vessels were filled with acrylic latex for vascular corrosion casting. The results showed ten variants of blood supply for the orbit, with a predominance of the first variant (66.1%) = bilateral presence of the external ophthalmic artery originating from the maxillary artery. Other variants differed in symmetry and asymmetry, sites of origination and the coexistence of both internal and external arteries. Vascularisation of the brain in chinchillas originates mainly from the vertebra-basilar system. The observed variability seems to confirm the role of the basilar artery in the arterial blood supply of the brain in this species.
