Function of myelin sheath
Describe the function of myelin sheath? Do all axons exist in myelin sheath?
Expert
The function of myelin sheath is to enhance the safety and speed of neural impulse transmission all along the axon. Myelin sheath serves as an electrical insulator defending the dispersion of the impulse to another adjacent structure. As the myelin sheath consists of gaps termed as Ranvier’s nodes in its length, then the neural impulse “jumps” from one node to the other therefore raising the speed of neural transmission.
Not all neurons encompass a myelin sheath. There are myelinated axonal fibers and un-myelinated ones.
