Vertebral canal
Vertebral Canal
The Vertebral Canal (pronounced: ver-te-bral ca-nal), also known as the spinal canal, is a bony channel within the vertebral column. It is formed by the vertebrae through which the spinal cord passes.
Etymology
The term "Vertebral Canal" is derived from the Latin word "vertebra", which means a joint or a segment of the spinal column, and "canalis" which means a pipe, tube, or a channel.
Anatomy
The vertebral canal is formed by the alignment of the vertebral foramina of individual vertebrae, which are stacked one on top of the other. The canal begins at the opening of the foramen magnum and ends at the sacral hiatus in the sacrum. It houses and protects the spinal cord and provides a conduit for nerves and vessels.
