摘　　要：本文对10只树鼩的脊髓进行了研究,树鼩的脊髓共有33个节段。其中颈髓8段,胸髓13段。腰髓6段,骶髓3段和尾髓3段。颈膨大位于颈3～颈8;腰膨大位于腰4～骶1。对各节段的径线及长度进行了测量,观察了脊髓的内部结构,包括脊髓中央管、灰质和白质,并叙述了灰质的板层结构。The segments and internal structures of the spinal cord of 10 tree shrews were studied. There are 33 segments in the spinal cord, i. e., 8 cervical, 13 thoracic, 6 lumbar, 3 sacral and 3 coccygeal. The cervical enlargement corresponds to the third to eighth cervical segment, and the lumbar enlargement corresponds to the fourth lumbar to first sacral segment. The length and diameters of the segments wrer measured. The intrenal structure of the spinal cord was observed, including the central canal, the white matter and the gray matter. And the structural lamination of the gray matter was described.
