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.
(Some molecules, such as glucose, are transported out of the blood by special methods.). Glial cells (astrocytes) form a layer around brain blood vessels and may be important in the development of the BBB. Astrocytes may be also be responsible for transporting ions from the brain to the blood.Some molecules, such as glucose, are transported out of the blood by special methods.).
