Are neurons in the brain myelinated

Efferent neurons — these take messages from the central nervous system (brain and spinal.Each of these wraps around and insulates a short length (about 1mm) of a single axon.Which can make contact with other neurons or effector cells.The only difference between myelination in the cns and the pns (peripheral nervous system) is the type of cell responsible for myelination.In addition, myelinated neurons comprise approximately 80% lipids.

However, unlike the plastic covering on an electrical wire, myelin.The brain is the only tissue with a large volume of nerve tissue.First, many neurons in the brain are myelinated.A neuron with unmyelinated axon has a comparatively lower speed of conduction of the nerve signals.~in myelinated neurons the impulse jumps from node of ranvier to node of ranvier.

However, in many areas of the brain there is a need for neurons not only to conduct as quickly as possible, but also synchronise conduction velocities.Schwann cells wrap around the axons of motor neurons.In the central nervous system, myelin is produced by oligodendroglia, whereas in the peripheral nervous system, it is produced by schwann cells.Myelin allows action potentials to propagate along an axon in a saltatory fashion with higher speed and less energy consumption.
