Anatomical terminology

The prevertebral space is a space in the neck.

On the other side, some sources define it as bounded by the vertebral bodies,[2] and others define it as bounded by the longus colli.[1]

It includes the prevertebral muscles (longus colli and longus capitis), vertebral artery, vertebral vein, scalene muscles, phrenic nerve and part of the brachial plexus.[3]

In trauma, an increased thickness of the prevertebral space is a sign of injury, and can be measured with medical imaging.[4]
