Broadly speaking, neuronal cells, including neuronal cells and glial cells, are specifically referred to as neuronal cells when nerve cells. Neurons are highly differentiated including three regions, which are the cytosol, dendrites, and axons. The cytosol is the main body of the neuron and varies greatly in size, sometimes by a factor of ten or more, as well as in the shape, number, and length of the protrusions. Dendrites are directly connected to the cytosol in a relatively short way and are able to transmit the received stimulus to the cytosol. Axons, on the other hand, are thin cords that extend outward from the cytosol, sometimes wrapping the myelin sheath outside. Axons are responsible for transporting nutrients and have a partial impulse transmission function. Myelinated axons rely primarily on the myelin sheath and the Langfinger’s node on which they are attached to conduct nerve impulses.
