Forget the traditional tubular shape—researchers are investigating a pearl-on-a-string formation for axons, unlocking new ...

Are all axons covered with myelin? No; they can be either myelinated or unmyelinated. Myelinated axons are ensheathed along their entire length. The axon caliber (diameter) in mammalian PNS ranges ...

Finally, we correlated the fraction of unmyelinated sciatic nerve axons in individual rats (of all treatment groups) with their individual motor performance (Fig. 4e). This yielded an inverse ...

The arrows point to the marked thickening of capillaries walls in the endoneurium. Abnormalities of unmyelinated fibers in severe length-dependent diabetic polyneuropathy. Electron micrograph of a ...
