fehérállománytérképezéssel

fehérállományt is the Hungarian term for white matter. In neuroanatomy, white matter refers to the areas of the central nervous system that are composed primarily of myelinated axons. These axons are nerve fibers that are covered in a fatty insulating sheath called myelin. The myelin sheath, which is white in appearance, allows for faster and more efficient transmission of nerve impulses.

White matter is found in both the brain and the spinal cord. In the brain, it forms tracts that connect different gray matter areas, which are composed of neuronal cell bodies and dendrites. These tracts are responsible for relaying information throughout the brain and between the brain and other parts of the body. Examples of white matter tracts include the corpus callosum, which connects the two cerebral hemispheres, and the internal capsule, which contains major ascending and descending pathways.

In the spinal cord, white matter is located on the periphery, surrounding the butterfly-shaped gray matter. The white matter in the spinal cord contains ascending tracts that carry sensory information from the body to the brain, and descending tracts that carry motor commands from the brain to the muscles. The arrangement and function of white matter are crucial for sensory perception, motor control, and cognitive processes. Damage to white matter can lead to a variety of neurological disorders, such as multiple sclerosis, which affects the myelin sheath.
