Redlich-Obersteiner's Zone
Encyclopedia
The Redlich-Obersteiner's zone is a boundary between the central nervous system
(CNS), the peripheral nervous system
(PNS). 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
. This narrow zone identified visually where there is a transition regarding myelin production.
As stated above, the Redlich-Obersteiner's zone separates the CNS and PNS. Thus at this point, there is a transition from Schwann cell
myelin meet to oligodendrocyte
myelin. Of note, in cranial nerves this is often the place of neuro-vascular compression syndromes such as trigeminal neuralgia.
Central nervous system
The central nervous system is the part of the nervous system that integrates the information that it receives from, and coordinates the activity of, all parts of the bodies of bilaterian animals—that is, all multicellular animals except sponges and radially symmetric animals such as jellyfish...
(CNS), the peripheral nervous system
Peripheral nervous system
The peripheral nervous system consists of the nerves and ganglia outside of the brain and spinal cord. The main function of the PNS is to connect the central nervous system to the limbs and organs. Unlike the CNS, the PNS is not protected by the bone of spine and skull, or by the blood–brain...
(PNS). 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
Spinal cord
The spinal cord is a long, thin, tubular bundle of nervous tissue and support cells that extends from the brain . The brain and spinal cord together make up the central nervous system...

As stated above, the Redlich-Obersteiner's zone separates the CNS and PNS. Thus at this point, there is a transition from Schwann cell
Schwann cell
Schwann cells or neurolemmocytes are the principal glia of the peripheral nervous system . Glial cells function to support neurons and in the PNS, also include satellite cells, olfactory ensheathing cells, enteric glia and glia that reside at sensory nerve endings, such as the Pacinian corpuscle...

Oligodendrocyte
Oligodendrocytes , or oligodendroglia , are a type of brain cell. They are a variety of neuroglia. Their main function is the insulation of axons in the central nervous system of some vertebrates...
