The Redlich-Obersteiner's zone |
The Redlich-Obersteiner's zone is a boundary of the centeral nervous sytem, seperating the PNS & CNS. The redlich-obersteiner's zone is located at the point of entry of the dorsal root into the spinal cord, which can be identified visually where there is a narrow zone. The narrow zone is a result of the relatively thin myelin sheath. This point is also the place where you find the last node of Ranvier before the axon enters the spinal cord. |

As stated above, the redlich-obersteiner's zone seperates the cns and pns. This means that at this point, you should see a shwann cell meet with an ogliodendrocyte. Recall that both of these cells produce the mylein sheath (PNS and CNS respectively). |
