The search for the functional understanding of the nervous system has resulted in an increase of morphological studies about encephalic vascularization in different animal species. The encephalic arteries are the main rote for blood transport to the brain and therefore have an essential role in the maintenance of normal brain activity. The functional importance of these vessels has led to various studies. The caroticobasilar artery was investigated in animals of order Perissodactyla, in species of Equidae family. The frequency of caroticobasilar artery was studied in 30 adult male crossbreed brain horses. The observations showed that this important vessel presented the following absolute and percentual frequencies: present in 15 (50%) brains 4 (13.3%) in the right antimere, 6 (20%) in the left antimere and 5 (16.7%) on both antimeres. |
