Vertebral column


 

The vertebral column (backbone or spine) is a column of vertebrae situated in the dorsal aspect of the abdomen.

Vertebral canal

The vertebral canal follows the different curves of the column; it is large and triangular in those parts of the column which enjoy the greatest freedom of movement, such as the cervical and lumbar regions; and is small and rounded in the thoracic region, where motion is more limited.
