Century Dictionary and Cyclopedia
- vertebrarterial Pertaining to a vertebra and an artery: specifically noting a foramen in the side of a cervical vertebra transmitting the vertebral artery. A vertebrarterial foramen is formed by the partial confluence of a rudimentary cervical rib, or pleurapophysis, with the transverse process proper, or diapophysis, of a cervical vertebra; the series of such foramina constitutes the vertebrarterial canal. This structure is one of the distinguishing characters of a cervical vertebra in man and many other animals. Also vertebro-arterial. See cut under cervical.
