Definition[Bearbeiten]
The foramina transversaria are bony openings in the processus transversi of the seven cervical vertebrae.
Anatomy[Bearbeiten]
The two vertebral arteries and their accompanying veins (vertebral veins), as well as sympathetic nerve fibres, pass through the transverse foramina of the 1st to 6th cervical vertebrae.
The transverse foramen of the 7th cervical vertebra (C7) is smaller than that of the other cervical vertebrae or may be completely absent. As a rule, it contains only the vertebral vein and a ramus communicans griseus of the inferior cervical ganglion. Only in rare cases can the vertebral artery also pass through the foramen as a variant.[1]
