Yes, the input from the peripheral nervous system to the central nervous system goes through the dorsal root ganglion (DRG) to the posterior horn of the vertebras. The bodies of the peripheral sensory neurons are located in the DRG.
The autonomic and motor pathways are located more forward in the lateral and anterior horn of the vertebras, they exists from separate locations (more forward) in the spinal column and doesn’t goes through the DRG.
