The vertebral nerve was found to be, in essence, a long and deep gray ramus communicans that connected most commonly the stellate ganglia to C6 or C7 spinal nerves by passing through the C6 and C7 transverse foramina. In contrast, sympathetic stimulation had pronounced effects on carotid flow and resistance. The effect of stimulation of the vertebral nerve and the cervical sympathetic trunk in the monkey was studied. Based on our review of the available literature and recent cadaveric research, it appears it may be more logical to classify the vertebral nerve as a variable ramus communicans that connects the stellate or inferior cervical ganglia to the lower cervical spinal nerves and not a structure that ascends entirely with the vertebral artery to enter the cranium.
