| | GlobalSpine - Advanced Anatomy - The Spinal Column |
 | | The Spinal Column, formed by the junction of the vertebrae, is situated in the median line, at the posterior part of the trunk; its average length in the male 71 cm, measuring along the curved anterior surface of the column. |
 | | On either side of the spinous processes, extending the whole length of the column is the vertebral groove formed by the lamina in the cervical and lumbar regions, where it is shallow, and by the lamina and transverse processes in the thoracic region, where it is deep and broad. |
 | | The base of that portion of the vertebral column formed by the twenty-four movable vertebras is formed by the under surface of the body of the fifth lumbar vertebra; and the summit by the upper surface of the atlas. |
