Studied were the structure and localization of the venous plexuses in the chewing muscles of a total of twenty newborn and growing lambs and sheep (aged up to 8 years) of both sexes through preparation, corrosion, and measuring. It was found that the venous plexuses were localized within the muscles and had definite boundaries. They were shown to be connected with the muscles and the periosteum of the neighbouring bones, and lay in the way of the emissary and bone veins and the veins that came from the muscles. The venous plexuses formed loops of a varying size and form, and the veins had two layer valvulae. In newborn lambs the plexuses were at birth well structured and localized. The venous vessels were found to be in close contact with the branching of the regional arteries. Numerical data are given concerning the size of the plexuses observed. It was assumed that these structures, beside their collecting the blood from the muscles, the rostral portion of the maxillary sinus, the alveolae of the last two molars of the maxilla, the brain and the venous sinuses in dura mater, are also of hemodynamic importance with regard to the correct distribution of the blood and its downward course (from the head to the neck).
通过解剖、腐蚀和测量，对20只新生及生长中的羔羊和绵羊（年龄至8岁）咀嚼肌内静脉丛的结构和定位进行了研究。结果发现，静脉丛位于肌肉内部且有明确边界。它们与肌肉及相邻骨骼的骨膜相连，位于导静脉、骨静脉以及来自肌肉的静脉的路径上。静脉丛形成大小和形状各异的环，静脉有两层瓣膜。新生羔羊的静脉丛在出生时结构良好且定位明确。发现静脉血管与区域动脉的分支紧密接触。给出了所观察到的静脉丛大小的数值数据。据推测，这些结构除了收集来自肌肉、上颌窦前部、上颌最后两颗磨牙的牙槽、大脑和硬脑膜静脉窦的血液外，对于血液的正确分布及其向下流动（从头部到颈部）也具有血液动力学意义。
