Abstract

The blood vessels of the vestibule and the endolymphatic duct and sac (ES) of the rat were reproduced with methacrylate casting medium and observed under a scanning electron microscope. Dense capillary networks of the macula utriculi and the macula sacculi were observed. The collecting venules from the vestibule emptied into the vein of the vestibular aqueduct (VVAQ). The plexus of the vessels in the ES was triangular in shape and had anastomoses with vessels of the bone and dura and drained into the VVAQ. The posterior meningeal artery (PMA) gave off two branches to the ES. These findings supported the similarity of the vascularization of the vestibule and the ES between the human and the rat.

摘要

用甲基丙烯酸酯铸型介质复制大鼠前庭及内淋巴管和内淋巴囊（ES）的血管，并在扫描电子显微镜下观察。观察到椭圆囊斑和球囊斑有密集的毛细血管网。前庭的集合小静脉汇入前庭导水管静脉（VVAQ）。ES内的血管丛呈三角形，与骨和硬脑膜的血管有吻合，并引流至VVAQ。脑膜后动脉（PMA）发出两支至ES。这些发现支持了人和大鼠在前庭和ES血管化方面的相似性。
