The present paper deals with the microscopic and submicroscopic structures of the peripheral nerve of the lumbar plexus and the skeletal muscle of the m. psoas major of the ancient female cadaver buried about 2100 years ago, which was excavated from the Han Tomb No. 1 at Mawangdui (Mawangtui) near Changsha, Hunan Province. The connective tissues in the peripheral nerve and the skeletal muscle of the ancient cadaver were found well preserved. Under the electron microscope were observed the characteristic periodic bands of the collagenous fibrils as well as some axons and degenerated myelin sheath in the lumbar plexus. And in some of the better preserved nerve fibers, their axons and myelin sheaths are readily discernible. In the m. psoas major, cross striations are clearly visible in some muscle fibers. The remains of a blood vessel with only their connective tissues left were observed in the nerve of the lumbar plexus. Bacterial spores appeared in the two tissues.
本文研究了约2100年前埋葬的古代女性尸体的腰丛周围神经和腰大肌骨骼肌的微观和亚微观结构，该尸体从湖南省长沙市附近马王堆一号汉墓出土。发现古代尸体周围神经和骨骼肌中的结缔组织保存完好。在电子显微镜下观察到腰丛中胶原纤维的特征性周期性条纹以及一些轴突和变性髓鞘。在一些保存较好的神经纤维中，其轴突和髓鞘清晰可辨。在腰大肌中，一些肌纤维可见明显的横纹。在腰丛神经中观察到仅留下结缔组织的血管遗迹。两种组织中均出现了细菌孢子。
