Vascularización encefálica del toro de lidia

As there are very few informations available in the literature about the blood vessels of the brain in the fighting-bulls, the authors studied them in three five-year old speciemens, injected with Rhodopax AX/85, blue and red, from the carotid arteries. Among all the anatomical details described, there is no caudal rate mirabile to be found, while the rostral one is well developed. Instead of the caudal net, a second circulus arteriosus can be described which is connected with the circulus arteriosus cerebri. Morphological details about size and situation of all these vascular elements are given.
