Resolution is the ability that a microscope has to distinguish fine details. Without making any other adjustments the RESOLUTION can be increased by focusing properly in a brightfield microscope.
A brightfield microscope (also called compound light microscope) is a light microscope that produces dark images against a bright background.
The brightfield microscope is widely used in cellular biology and microbiological laboratories.
The resolution of the brightfield microscope is limited to 0.2 micrometers (µm).
This maximum value can be reached by changing the objective lens.

Answer:
Oligodendrocytes in the brain and spinal cord and Schwann cells in the peripheral nervous system are specialized types of glia that build the myelin sheaths that surround neurons.
Explanation:
Myelin sheath is an insulating layer, which covers neurons. It is made up of protein and fatty substances. This myelin sheath permits electrical impulses to move very fast along the neurons.
