What is the vital role of neurons that glial cells cannot perform
1 Neurons have TWO processes called axons and dendrites....glial cells have only ONE. 2  Neurons CAN generate action potentials...glial cells CANNOT. 3  However, glial cells do have a resting potential. 4  Neurons HAVE synapses that use neurotransmitters...glial cells do NOT have chemical synapses. However, glial cells do have a resting potential. 2  Neurons HAVE synapses that use neurotransmitters...glial cells do NOT have chemical synapses. 3  There are many MORE (10-50 times more) glial cells in the brain compared to the number of neurons.
