The region that is responsible for insulation is?

The region responsible for insulation in the nervous system is primarily the myelin sheath, which encases the axons of neurons. This fatty layer enhances the speed and efficiency of electrical signal transmission along the nerve fibers. Myelin is produced by glial cells, specifically oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. Insulation provided by myelin is crucial for proper neural communication and overall nervous system function.
