What makes up the white matter of the brain?

Question

Quizplus · Accepted Answer

The white matter of the brain is predominantly made up of myelinated fibers. These fibers are responsible for transmitting signals between different areas of the brain and allow for efficient communication between neurons. While unmyelinated fibers and neuron cell bodies can be found in the brain, they do not make up the majority of the white matter. Gyri, on the other hand, refer to the ridges or bumps on the surface of the brain and are not a component of the white matter.
