颅内颈动脉网(或硬膜外网)是一种独特的血管系统，供应偶趾类动物的大脑，这些偶趾类动物要么有一条颈内动脉，要么没有。尽管较小和较大的鼠鹿(分别为爪哇黄腹鹿和油菜鹿)是反刍动物，但硬膜网是不存在的。在这些动物中，就像在非偶指目动物中一样，如狗、马和人类，完整的颈内动脉供应大脑。目前还不确定该rte的缺失是否仅限于反刍动物中的鼠鹿。小鼠鹿体内网状结构的缺失为偶指目动物动脉系统的进化提供了新的见解。
The intracranial carotid rete (or rete mirabile epidurale) is a unique blood vascular system supplying the brain of artiodactyls, which have either an involuted or no internal carotid artery. Although the lesser and greater mouse deer (Tragulus javanicus and T. napu, respectively) are ruminants, the rete mirabile epidurale is absent. In these animals, as in non-artiodactyls, such as canines, equines and humans, the complete internal carotid artery supplies the brain. It is currently uncertain whether the absence of the rete is confined to mouse deer among ruminants. The absence of the rete in mouse deer provides new insights into the evolution of the arterial system in artiodactyls.
