MRT with contrast medium In order to be able to see exactly what the lesions are, it is important that an MRI of the brain is also done with the help of a contrast medium (usually gadolinium). This contrast medium is injected into the vein and is then distributed throughout the body, including the brain. … MRT with contrast medium | MRT for multiple sclerosis
Myelin is a fatty substance that surrounds many nerve cells. Since it is spirally wrapped around the nerve cells, the structure that is created is called a myelin sheath. Myelin sheaths are found both in the central nervous system, i.e. in the brain, and in the peripheral nervous system, i.e. in all other nerves that … Myelin sheath
Diseases The most common and best known disease of the myelin sheaths is multiple sclerosis. Here, the human body forms antibodies against precisely these cells that form the myelin sheaths, the oligodendrocytes. These are thereby destroyed. In multiple sclerosis, the myelin sheaths of the central nervous system are affected, i.e. those of the brain and … Diseases | Myelin sheath
Synonym axial cyinder, Neurit General information The term axon is used to describe the tubular extension of a nerve cell that transmits impulses originating from the nerve cell body to the farthest reaches. Within the axon is a fluid, the axoplasm, which corresponds to the cell content (cytoplasm) of other cells. Here are cell organelles … Axon
Tasks An axon fulfils two important tasks: First, it is there to transmit the electrical impulses generated in the nerve cell body to the next nerve cell or to the target structure (muscle or gland cell). – In addition, some substances are transported along certain structures through the axon. This process, known as axonal transport, … Tasks | Axon
