Abstract:
ObjectiveTo explore the projections of the long descending propriospinal tracts to lumbar enlargement. Method Anterograde tracing with cupric-silver staining. 10 animals were injected b biotinylated dextran in the upper cervical cord. Following survival times of 14 days, projections of the long descending propriospinal tracts were immunohistochemically demonstrated in the lumbar enlargement.Results The degenerated terminals and labeled terminals were found in the bilateral gray matter of the lumbar enlargement, but predominantly ipsilaterally. The terminals were widely distributed in laminal Ⅴ-Ⅸ, heavily Ⅶ and Ⅷ. Conclusion The long descending propriospinal tract from the upper cervical cord projects to the lumbar enlargement.
