How does a myelin sheath form?
The myelin sheath is an extruded plasma membrane wrapped in a spiral fashion around a nerve axon. The myelin membranes are part of the Schwann cells of the peripheral nervous system.
The layer of lipid around an axon is called?
Myelin sheath
What does myelin sheath wrap around?
The myelin sheath wraps around the around the axon of a neuron. The gaps of the myelin sheath are not insulated and are therefore capable of generating electrical activity.
What is the fatty tissue that covers axons and speeds up impulses as they travel from cell to cell?
That substance is called the myelin cell or myelin sheath.
Formation of Myelin Sheath and also Neuron introduction?
The formation of myelin sheath around the axon is called the myelinogenesis. In the peripheral nerve, the myelinogenesis starts at 4th month of intrauterine life. It is completed only in the second year after birth. Before myelinogeneis, Schwann cells of the neurilemma are very close to axolemma as in the case of unmyelinated nerve fiber. The membrane of the schwann cell is double layered. The schwann cells wrap up and rotate around the axis cylinder in many concentric layers. The concentric layers fuse to produce the myelin sheath but the cytoplasm of the cells is not deposited. Outermost membrane of Schwann cell remains as neurilemma. Nucleus of these cells remains in between myelin sheath and neurilemma. In the central nervous system, the schwann cells are absent and the myelin sheath is formed by the neuroglial cells called the oligodendroglia.
