The process by which if insulating myelin is present on an axon then the nerve impulses that is conducted will “jump” from gap to gap in the myelin layer. Salta in spanish= jump. How does saltatory conduction occur in axon? The arrival of positive ions at this node depolarises thisRead More →
Myelin is made by two different types of support cells. In the central nervous system (CNS) — the brain and spinal cord — cells called oligodendrocytes wrap their branch-like extensions around axons to create a myelin sheath. In the nerves outside of the spinal cord, Schwann cells produce myelin. AreRead More →
By acting as an electrical insulator, myelin greatly speeds up action potential conduction (Figure 3.14). For example, whereas unmyelinated axon conduction velocities range from about 0.5 to 10 m/s, myelinated axons can conduct at velocities up to 150 m/s. Are Unmyelinated axons related to saltatory conduction? Saltatory conduction in unmyelinatedRead More →
