WebbSchwann cell, also called neurilemma cell, any of the cells in the peripheral nervous system that produce the myelin sheath around neuronal axons. Schwann cells are named after German physiologist Theodor Schwann, who discovered them in the 19th century. These cells are equivalent to a type of neuroglia called oligodendrocytes, which occur in the … WebbAs myelin sheath is covering around the axon, one of its functions is to serve as a separating layer for the axon from the extracellular components. However, it is mainly involved in increasing the velocity of nerve impulse conduction for a quick response. Myelin has low capacitance and high electrical resistance and can act as an insulator.
