“…The caudal communicating artery in A. belzebul presents itself as a branch of the union of the internal carotid artery with the caudal cerebral artery, and its course runs laterally to the cerebral hemisphere to supply the pituitary and nipple bodies. In S. libidinosus (Ferreira & Prada 2009), the caudal communicating artery has the same configuration, which delimits the caudal part of the arterial circle with the vertebra-basilar system.…”

“…The arterial circuit of the base of the brain has been described by other authors aiming at detailing the brain vascularization in comparative character between human, non-human primates and other vertebrates (Ferreira & Prada 2009, Prada 2014. The arterial circle is a very important vascular pathway of the brain.…”

Vascularization of the Alouatta belzebul brain base

ABSTRACT: We studied the arterial circle in the brain of five specimens of the Alouatta belzebul primate. The material had the arterial system perfused (water at 40°C), injected with stained latex (Neoprene 650), fixed in aqueous formaldehyde solution (10%) and dissected for vessel verification. The arterial circle of this primate is composed of two vascular systems: the vertebra-basilar and the carotid ones, which anastomose to close the arterial circuit. In the caudal portion of the arterial circle, there are the vertebral arteries and their branches: the rostral spinal artery and the caudal inferior cerebellar artery. The anastomosis of the vertebral arteries gives rise to the basilar artery. It presented an anatomical variation at the beginning of its path, forming a double basilar artery, called arterial island. In its course, it emitted branches giving rise to the rostral inferior cerebellar artery, the pontine arteries, the rostral cerebellar arteries, the satellite rostral cerebellar arteries and its terminal branch, the caudal cerebral artery, which presented itself in two segments: the pre-communicating one and post-communicating, joining the internal carotid artery and originating the caudal communicating artery. This group of arteries and anastomoses enclose the caudal portion of the arterial circle. From the right and left internal carotid arteries begins the rostral portion of the arterial circle, which consists of the right and left rostral cerebral arteries and the right and left middle cerebral arteries. The rostral cerebral arteries anastomose into a single trunk, giving rise to the interhemispheric artery, and in A. belzebul and Sapajus libidinosus, the rostral communicating artery is absent. The interhemispheric artery goes to the midbrain region and the corpus callosum knee divides into pericalous artery and callosarginal artery, which will supply the pre and post-central regions of the cerebral hemispheres of this species, as well as other non-human and human primates. It is noted that in the first part of the left rostral cerebral artery, there is a direct inosculation between the recurrent branch of the rostral cerebral artery and left middle cerebral artery to supply the entorhinal region. This fact also occurs in Pongo spp. The middle cerebral artery travels along the lateral sulcus where it emits several superficial branches to irrigate the superior and inferior lateral cortical regions of the frontal, parietal and temporal lobes. It is not part of the arterial circle but is the terminal branch of the internal carotid artery. A. belzebul can be considered to depend on two sources of supply to the brain: the vertebra-basilar and carotid systems, contributing to the intervention of veterinarians during clinical and surgical procedures in other primates, as well as the preservation of wild animals.

“…O circulo arterial apresentou-se fechado caudalmente pela anastomose das artérias comunicantes caudais ou ramo caudal da carótida interna com a artéria basilar em todas as espécies domésticas (DYCE et al, 2007) e diversas selvagens já descritas como, por exemplo, no javali (CÂMARA FILHO et al, 2004) e no macaco prego PRADA, 2009). Em espécies que possuem a irrigação encefálica suprida unicamente pela artéria basilar característica do modelo III proposto por Tandler (1898), como a nutria descrita por Azambuja (2006) e a chinchila descrita por Araújo (2004), embora o círculo apresente-se igualmente fechado estes autores optaram por descrever a parte caudal do circuito como uma bifurcação da artéria basilar não adotando a nomenclatura de artérias comunicantes caudais, visto que a artéria carótida não está presente.…”

Aceito para publicação em 12/03/2014 Resumo O Eira barbara é um mustelídeo de ampla distribuição na América latina vulgarmente conhecido como Papa-mel. Tendo em vista a carência de informações a respeito da anatomia dos mustelídeos, assim como a importância de um modelo vascular para a compreensão das lesões neurológicas no sistema nervoso central, este trabalho objetivou descrever a morfologia e a composição do circuito arterial da base do encéfalo do E. barbara fornecendo dados para estudos futuros. Para tal utilizou-se dois espécimes, machos, jovens, provenientes, da área de Mina Bauxita Paragominas-PA, doados após morte ao LaPMA. Os espécimes tiveram o sistema arterial preenchido com látex Neoprene 650 corado em vermelho e foram fixados em formaldeído 10% sendo posteriormente dissecados para sistematização dos vasos. Os animais estudados apresentaram o circuito arterial da base do encéfalo suprido pelas artérias carótidas internas e artéria basilar. A artéria carótida interna, após atravessar a dura-máter, continuou cranialmente emitindo as artérias cerebrais médias e terminando como artérias cerebrais craniais que se anastomosam fechando rostralmente o circuito arterial. As artérias comunicantes caudais integraram a artéria basilar ao circulo arterial e emitiram as artérias cerebrais caudais e cerebelares rostrais. A artéria basilar revelou como principais ramos, as artérias cerebelares médias e caudais.

This study aimed to describe the brain base arteries of the Myrmecophaga tridactyla using ten cadavers of adults from this species, including five male and five female specimens. The arterial vascular bed was perfused via the thoracic aorta with a dyed natural latex solution, and the animals were fixed and preserved with a 10% formaldehyde buffered solution. The encephala were removed, and their vessels dissected. Basilar artery formation occurred by anastomosis of the thick ventral spinal artery with vertebral arteries. The basilar artery formed two arterial islands and gave bulbar and pontine branches, and cranial, middle, and caudal cerebellar arteries and ended by forking into its terminal branches, the caudal communicating arteries. The blood supply of the encephalon derived solely from the vertebrobasilar system, and the arterial circle of the brain was closed caudally and rostrally. The absence of participation of internal carotid arteries in encephalon irrigation, the island formations by the basilar artery, and the fusiform shape of the arterial circle of the brain are peculiar characteristics of the vascular anatomy of the brain base of M. tridactyla.
