Support and brace neurons
Anchor neurons to their nutrient supplies (capillaries)
Control the chemical environment
the most abundant CNS neuroglia
Phagocytes - protection from disease
defensive cells in the CNS.
Line the central cavities of the brain and spinal cord
Produce CSF (cerebrospinal fluid)
Cilia to help circulate CSF
line cerebrospinal fluid-filled cavities
Branched cells that wrap around axons of neurons
Myelin - phospholipid covering, insulating function
have processes that form myelin sheaths around CNS nerve fibers.
