Abstract: Objective    To demonstrate the anatomical relationship between superior cervical ganglion (SCG) and second cervical nerve (C2) and the innervated branch from SCG to vertebral artery, for providing anatomical basis for the clinical diagnosis of the upper cervical vertigo.    Methods    Fifteen adult cadavers (total 30 sides) were dissected  to observe the communicating branches of SCG with C2 and the branches of the vertebral artery.   Results   There was no neural connection between SCG and C2 in 5 sides. There were neural connection between SCG and C2 in the remaining 25 sides, of which the vagus nerves were involved in 18 sides. The innervated branches were found from SCG to vertebral artery in 7 sides. After the SCG branch merged with the anterior branch of C2, the sympathetic nerve fibers were transferred to the anterior and posterior branches of C2 and the vertebral artery respectively.    Conclusions   The communicating branches of SCG and C2 and their dominant relationship to the vertebral artery can provide important anatomical basis for elucidating the pathogenesis of upper cervical vertigo and establishing effective treatment plan.
