The external vertebral venous plexuses (extraspinal veins) best marked in the cervical region, consist of anterior and posterior plexuses which anastomose freely with each other.

  • The anterior external plexuses lie in front of the bodies of the vertebræ, communicate with the basivertebral and intervertebral veins, and receive tributaries from the vertebral bodies.
  • The posterior external plexuses are placed partly on the posterior surfaces of the vertebral arches and their processes, and partly between the deep dorsal muscles.

    • They are best developed in the cervical region, and there anastomose with the vertebral, occipital, and deep cervical veins.
