Question

Quizplus · Accepted Answer

The distinctive shape of a neuron, with its axon and dendrites, is the main feature that distinguishes it from other animal cells. While neurons may have larger nuclei than some other cells, this is not the defining characteristic of neurons. Neurons do have the ability to metabolize a variety of fuels, but this is also true of many other cells. Internal concentration of sodium ions varies depending on the function and location of the cell, so it is not a feature that consistently distinguishes neurons from other cells.
