摘　　要：目的：探究成年羊蹄部动脉血管起源、分支、分布、走向及血管床构筑特征，为哺乳动物比较解剖学和蹄病临床治疗提供形态学依据。方法：运用大体解剖学方法和管道铸型技术对羊蹄部动脉血管床构筑进行系统观察和测量。结果：成年羊前肢蹄部动脉的主要分支有第3和第4指枕动脉、第3和第4指掌侧固有动脉、远指节骨终动脉弓、中指节骨掌（背）侧动脉、第3和第4指掌远轴侧固有动脉；后肢蹄部的趾枕动脉多数由第3和第4趾背轴侧固有动脉，少数由趾间动脉分出，趾枕动脉后的分支与前肢蹄部相应血管分支基本相同。结论：羊蹄部动脉在前肢主要是第3和第4指枕动脉以及第3和第4指掌侧固有动脉的延续和分支，后肢主要是趾背侧第3总动脉的直接延续和分支，各级动脉分支相互吻合，形成了一套完整的动脉血管床。Objective： To provide morphology for the mammal comparative anatomy and clinical freatment, the originate branches, distribution, direction of sheep hoof arterial vessel and the character of the vessel bed construction were studied. Methods： The macroscopic anatomy and tubing cast technique were used to observe and measure the arterial vessel bed construction of sheep hoof. Results： In the adult, the fore-limb distribution mainly contained a tori digitalis Ⅲ and Ⅳ axial artery, digitalis palmaris Ⅲ and Ⅳ axiales ramus, anterior dorsalis distalis, anterior phalangis olorsalis meaiae, anterior arterial and digitales palmaris propria Ⅲ and Ⅳ axial; the toe-occipital artery of hind limb was mainly branched by axial artery digitalis palmaris Ⅲ and Ⅳ axiales and some was branched by artery interdigitalis. The post branches of the toe-occipital artery were same as the fore-limbs. Conclusion： The fore-limb distribution mainly contain a tori digitalis Ⅲ and Ⅳ axial artery, digitalis palmaris Ⅲ and Ⅳ axiales ramus, and at the hind limb, mainly contain the stretches and the branches of arterial digitalis palmaris communis Ⅲ. Each class branch is inosculated mutually, and a complete arterial bed is formed.
