'' Whonamedit?'' (accessed 5 June 2022) The Redlich–Obersteiner's zone is located at the point of entry of either between cranial nerves and the brain or spinal nerves and the

spinal cord The spinal cord is a long, thin, tubular structure made up of nervous tissue that extends from the medulla oblongata in the lower brainstem to the lumbar region of the vertebral column (backbone) of vertebrate animals. The center of the spinal c ...

. This narrow zone is identified visually where there is a transition regarding myelin production. It is named after Emil Redlich and Heinrich Obersteiner. As the Redlich–Obersteiner's zone separates the CNS and PNS, there is a transition from
