Brain trauma and diffuse axon injury in the Corpus Callosum

Diffuse axonal injury: Trauma that is strong enough to break long slender blood vessels is usually strong enough to break long delicate axons, too.  Therefore, the presence of gross microhemorrhages in long white matter tracts, such as the corpus callosum, strongly suggests that diffuse axonal injury will be seen on microscopic evaluation of the axons comprising these white matter tracts. The image shows... Continue Reading →

Nerve Root

This image of a nerve root shows axons myelinated by oligodendroglial cells of the central nervous system (top of image) and Schwann cells of the peripheral nervous system (bottom of image) at a point of transition called the Obersteiner-Redlich zone.
