CENTRAL NERVOUS SYSTEM

BRAIN

WHITE MATTER

Most of its volume is occupied by axons arranged in bundles and for this reason its sections have a fibrillar aspect.
Histological sections of the white matter exhibit fewer nuclei than the gray matter, most of them belonging to neuroglial cells (highlighted in blue). Oligodendrocytes are especially numerous, as they surround the axons that cross the white matter.
Nuclei of blood capillaries endothelial cells can be observed (their lumen highlighted in red).
