Abstract
The purpose of our study was to evaluate the individual variations of the foramen transversarium of the seventh cervical vertebra. This foramen sometimes has the same dimensions as the foramina of the other cervical vertebrae, but it can also be smaller, or absent. In cases where a foramen is present in the seventh cervical vertebra, vascular or nerve structures (or both) can be occasionally observed within. When the transverse foramina are found to contain none of the above structures, what then is to be found within this space? According to our results, the transverse foramina of the seventh cervical vertebra almost always contains vascular and nerve branches as well as fibrous and adipose tissues. This report concerns the results of the macroscopic and microscopic studies concerning the contents of the transverse foramina of the sixth and seventh cervical vertebrae. The comparative study was completed at the Department of Anatomy of the Faculty of Medicine, University Laval.
