Summary
Ultrastructural analysis of myelin is crucial for understanding nerve damage in neurological disorders. Standardized terminology for myelin changes aids diagnosis and therapeutic strategies.
Area of Science:
- Neuroscience
- Cell Biology
- Pathology
Background:
- Ultrastructural evaluation of myelin is key to understanding pathological changes affecting nerve function.
- Existing terminology for myelin alterations is varied, hindering consistent interpretation.
- A unified terminology is needed for better structure-function relationship interpretation in neurological disorders.
Purpose of the Study:
- To present examples of ultrastructural myelin changes during myelination, demyelination, re-myelination, and dysmyelination.
- To review and consolidate existing terminology for describing myelin ultrastructure.
- To provide a guide for future ultrastructural studies in neurological disorders.
Main Methods:
- Review of studies reporting ultrastructural findings of myelin.
- Inclusion of studies without limitations on experimental conditions, species, or disorders.
- Compilation of descriptive terms for myelin structural alterations.
Main Results:
- Examples of ultrastructural myelin changes are presented, including compacted, partially compacted, and noncompacted myelin.
- Terminology reviewed includes terms for redundancy (hypermyelination, tomacula), splitting, degradation, and cellular changes.
- A comprehensive list of descriptive terms for myelin alterations is provided.
Conclusions:
- Ultrastructural evaluation of myelin is highly valuable for understanding pathological and physiological changes in neurological disorders.
- Standardized terminology will empower diagnosis and therapeutic approaches.
- Future studies should integrate quantitative methods with ultrastructural findings for enhanced insights.

The myelin sheath is a multilayered lipid and protein covering that insulates the axon of a neuron, enhancing the speed of nerve impulse conduction. Axons without this sheath are referred to as unmyelinated. Two types of neuroglia, Schwann cells in the peripheral nervous system (PNS) and oligodendrocytes in the central nervous system (CNS) are responsible for producing myelin sheaths.
Schwann cells begin to form myelin sheaths around axons during fetal development. They wrap around a small...

1.5K
In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...
