More primitive structures are at the bottom (brainstem) and more sophisticated structures at the top (cerebral cortex). Support cells that help the neurons physically and metabolically. Regulate transmission of electrical impulses in the brain. Insulates the axon helping the nerve impulse to travel faster. So the ions have a spot to enter the axon. When it enters the synapse, the electrical signal changes to a chemical signal. Ions are switching back to their original places. No new action potential can take place. Spatial: more than one neuron innervating one neuron. Acetylcholine: cervical enlargement: c4 to t1, lumbosacral enlargement: t11 to l1.
