Ten human adult spinal cords were assessed for weight, length, thickness, cholesterol, water and DNA-P content on both a regional and a mean segmental regional basis. The mean segmental DNA-P content, unlike the other parameters, was exceptional in being constant in the cervical, thoracic and lumbar regions. It is concluded that the cellularity of the cord between C1 and L5 is determined segmentally, but is reduced in the segments of the sacrococcygeal cord because of embryonic atrophy.
对10条成年人类脊髓进行了评估，分别从区域和平均节段区域两个层面测定其重量、长度、厚度、胆固醇、水分和DNA-P含量。与其他参数不同，平均节段DNA-P含量在颈段、胸段和腰段保持恒定，这一情况较为特殊。得出的结论是，C1至L5节段脊髓的细胞构成是按节段确定的，但由于胚胎期萎缩，骶尾段脊髓的细胞构成减少。
