The height of the vertebral growth zones of 13 adolescents dying between the ages of 13 and 18 years was determined with the aid of an eyepiece micrometer. In addition, the proportion 'total of widths of chondrocyte columns/diameter of the growth zone' was established. In the cervical spine, the growth zones of the caudal end plates were significantly higher than those of the cranial end plates. The reverse was true for the thoracic vertebrae. In the lumbar spine, however, conditions resembled those found in the cervical spine in that the caudal end plates were higher than those of the cranial plates; yet, there was no statistically significant difference in the relative quota 'chondrocyte columns/diameter of growth zone' in this segment of the spine. These results suggest that lengthwise growth of cervical and lumbar vertebrae is more marked in the caudal than in the cranial end plates, whereas, in the thoracic spine, growth of the cranial exceeds that of the caudal end plates. Moreover, the height of the growth zones increases in a craniocaudal direction, a fact which could be related to the more marked growth of lumbar as compared to cervical or thoracic vertebrae.
借助目镜测微计测定了13名年龄在13至18岁之间死亡的青少年椎骨生长区的高度。此外，还确定了“软骨细胞柱总宽度/生长区直径”的比例。在颈椎中，尾端终板的生长区明显高于头端终板。胸椎的情况则相反。然而，在腰椎中，情况与颈椎相似，即尾端终板高于头端终板；然而，在该节段脊柱中，“软骨细胞柱/生长区直径”的相对配额没有统计学上的显著差异。这些结果表明，颈椎和腰椎的纵向生长在尾端终板比在头端终板更明显，而在胸椎中，头端终板的生长超过尾端终板。此外，生长区的高度沿头尾方向增加，这一事实可能与腰椎比颈椎或胸椎生长更明显有关。
