Explanation / Answer

Answer:- Myelin sheaths.

If myelin sheaths are absent in neurons than saltatory conduction is not possible because saltatory conduction occurs in myelinated axons from one node of Ranvier to next. Mylinated axons are those which are insulated by myelin ( a sheath which is made up of lipids and proteins).
