Axons are covered by a myelin sheath formed by Schwann cells, which provides insulation and increases the speed of nerve impulse transmission through saltatory conduction.
تُغلف المحاور العصبية بغمد المايلين الذي تُشكله خلايا شوان، مما يوفر العزل ويزيد من سرعة نقل النبضات العصبية عن طريق التوصيل القفزي.
| Front | myelin sheeth, schwann cells and speed |
|---|---|
| Back | axons of some neurones covered in myelin sheeth (layers of plasma membrane), schwann cells form layers by growing around axons (each time a double phospholipid bilayer is layed down), myelin sheeth insulation layer allows neurones to conduct electrical impulses faster |
