A c-fos labeling study on the neuronal pathway connection between the cervical spinal cord and the lumbar spinal cord

Objective:To investigate the neuronal pathway connection between the cervical spinal cord and the lumbar spinal cord with c-fos labeling. Method: 20 male SD rats were operated to expose and grind the left sciatic nerve with forceps. The cervical and lumbar spinal cord was taken out 2 hours after the operation.Then the immunochemical labeling of the c-fos was done. Result:The anterior corner cell and posterior corner cell with c-fos labeling were found in the left lumbar spinal cord(L4-6),and it was found in the anterior corner of the two side cervical spinal cord(C5-8) too.Conclusion: There is neural pathway connection between the cervical spinal cord and the lumbar spinal cord.
