Compared to Neurons, Glial Cells That Have Become Depolarized Take

Multiple Choice

Compared to neurons, glial cells that have become depolarized take a relatively long time to return to resting potential. What is one possible reason for this?

A) Glial cells are smaller than neurons and have fewer ion channels.
B) Glial cells have lower resting potentials than neurons.
C) Neurons are myelinated, which contributes to the speed of their return to resting potential.
D) Potassium spreads through networks of glial cells, which slows the return to resting potential.
E) Calcium waves through glial networks prevent potassium from reentering the glial cells.
