The objective of the present investigation was to conduct a comparative macroscopic study of the arterial vascularization of the mandible and maxilla of neotropical primates of the genera Cebus, Alouatta, Callithrix, and Leontopithecus. After vinyl was injected into the arterial system of the head of each specimen, the pieces were macerated and corroded. The level of the bifurcation of the common carotid artery into the internal and external carotids varied between the first and third cervical vertebrae. The external carotid artery accounts for most of the vascularization of the facial structures. The actual vessels responsible for the supply of this region are the sublingual, facial, angular, lingual, submandibular, submental, inferior and superior labial, maxillary, inferior alveolar, infraorbital, superior posterior alveolar, palatine major, and sphenopalatine arteries. We conclude that although the arterial vascular pattern was similar in all the genera studied, and resembles the human pattern, there are notable variations in the vasculature of the mandible and maxilla among these four neotropical genera.
本研究的目的是对僧面猴属、蛛猴属、狨属和狮面狨属新热带灵长类动物的下颌骨和上颌骨的动脉血管形成进行比较宏观研究。在将乙烯基注入每个标本头部的动脉系统后，将组织块进行浸软和腐蚀处理。颈总动脉分为颈内动脉和颈外动脉的分叉水平在第一和第三颈椎之间变化。颈外动脉是面部结构大部分血管形成的原因。负责该区域供血的实际血管是舌下动脉、面动脉、内眦动脉、舌动脉、下颌下动脉、颏下动脉、上下唇动脉、上颌动脉、下牙槽动脉、眶下动脉、上牙槽后动脉、腭大动脉和蝶腭动脉。我们得出结论，尽管在所研究的所有属中动脉血管模式相似，且与人类模式相似，但在这四个新热带属的下颌骨和上颌骨的脉管系统中存在显著差异。
