-Has myelin sheath or medullated sheath which is a fatty sheath that encloses the axon hence insulate the axon and impluses.

-Has Schwann cell that are in close contact with axon and they secrete the myelin sheath.

-myelin sheath has constrictions at intervals – called nodes of Ranvier to propagate the nerve impulse and speed up the transmissions of an impulse

b) –Inner membrane is greatly folded to form cristae which increase surface area for respiratory activity
