12 Difference Between Myelinated And Unmyelinated …

WebThe transmission of impulses through the neuron is called propagation or conduction of nerve impulses. The impulse transmission is by electrical potential and wave like. The neurons are two types based on presence and absence of myelin sheath. They are myelinated and non-myelinated neurons. Web7 apr. 2024 · The myelinating cells form the myelin sheath of large axons (larger than 1 μm diameter). The non-myelinating cells ensheath small axons forming unmyelinated fibers, called Remak bundles, or they migrate toward the neuromuscular junctions, where they become terminal/perisynaptic/teloglia Schwann cells ( Figure 3 ).
