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 ...

Medically reviewed by Huma Sheikh, MD Neurons are the cells in our body that are responsible for transmitting electrical ...

It consists primarily of myelinated axons—long, thread-like projections of nerve cells (neurons) coated in myelin, a fatty substance that insulates and speeds up electrical signals. These axonal ...
