Glial cells and neurons
WebMajor glial cells in the brain include oligodendrocytes (blue), astrocytes (green) and microglia (maroon). Neurons are shown in yellow, with the blue of oligodendrocytes forming the myelin sheath around the axon. (Image: … WebGlial cells are supporting cells, maintaining the environment around the neurons. Neurons are polarized cells, based on the flow of electrical signals along their membrane. Signals are received at the dendrites, are passed along the cell body, and propagate along the axon towards the target, which may be another neuron, muscle tissue, or a gland.
