myelinöivät
Myelinöivät is a Finnish term that translates to "myelinating" or "myelination" in English. It refers to the process by which a myelin sheath is formed around a nerve fiber, also known as an axon. This sheath is a fatty, insulating layer that is crucial for the efficient transmission of nerve impulses. Myelination is primarily carried out by specialized glial cells. In the central nervous system (CNS), these cells are oligodendrocytes, while in the peripheral nervous system (PNS), they are Schwann cells.
The myelin sheath is not continuous along the axon. Instead, it is segmented, with small gaps called
Myelination begins during fetal development and continues throughout childhood and adolescence. It is a critical process
