TELENCEPHALON VASCULARITY IN COMMON FOX (Vulpes vulpes)
Abstract
The studies of the vascularization of the cerebrum in common fox were performed on 80 cerebral hemispheres. It was found that the middle cerebral artery is the strongest vessel supplying blood to the cerebrum. The artery gets divided into ten permanent branches. Two olfactory arteries supply the region of the cerebrum located on the border between the old and the new cortex. The other eight are divided into three branches heading towards the frontal lobe of the brain, two branches heading towards parietal lobe and three temporal branches heading towards the temporal part, that supply the region of the new cortex. The frontal, parietal and temporal branches descended independently from the main trunk of the middle cerebral artery or formed a common trunk. Common trunks for respective groups of branches have been described as the rostral, dorsal and caudal middle cerebral artery. In 7.5% of cases there were two independent branches of the middle cerebral artery extending from the rostral cerebral artery. Key words: brain arteries; common fox PREKRVAVLJENOST TELENCEFALONA PRI LISICI (Vulpes vulpes) Študije o prekrvavitvi možganov so bile opravljene na hemisferah 40 lisic. Ugotovljeno je bilo, da je srednja možganska arterija najmočnejša žila za dovod krvi v možgane. Arterija se razdeli na deset stalnih vej. Dve vohalni arteriji oskrbujeta področje v možganih, na meji med staro in novo skorjo. Drugih osem vejoskrbuje območje nove skorje: tri se razvejajo v smeri čelnega režnja, dve v smeri temenskega in tri v smeri senčnega režnja možganov. Čelne, temenske in senčne veje se spuščajo neodvisno od glavnega debla srednje možganske arterije ali pa oblikujejo skupno deblo. Skupna debla za posamezne skupine vej so bila opisana kot rostralna, dorzalna in kavdalna sredinska arterija. V 7,5 % primerov sta bili opaženi dve neodvisni veji srednje možganske arterije, ki se nadaljujeta od rostralne možganske arterije. Ključne besede: možganske arterije; lisica
