neuron
Myelin sheats insulate the axon from electrical activity. This insulation increases the rate of transmission of signals, which spring from gap to gap.
Postsynaptic neuron receptors (dendrite) receive emitted neurotransmitters from presynaptic neuron (axon) - closeup view 3d illustration
Myelin sheats insulate the axon from electrical activity. This insulation increases the rate of transmission of signals, which spring from gap to gap.

White matter: neurons with myelinated axons, oligodendrocytes forming the myelin sheaths, fibrous astrocytes and microglia cells
Oligodendrocytes form insulating myelin sheaths around neuron axons in the central nervous system. One oligodendrocyte can extend its processes to 50 axons. Myelin increases the impulse speed and decreases the capacitance of the axon membrane.
Brain cells: astrocytes (red), pyramidal neurons (red), microglia cells (blue)
Motor neuron: neuron in contact with muscle fibers.
