Neuroglia Oligodendrocytes Microglia Satellite cells Schwann cells Astrocytes Surround neuron cell bodies in ganglia; regulate O2, CO2, nutrient, and neurotransmitter levels around neurons in ganglia Surround all axons in PNS; responsible for myelination of peripheral axons; participate in the repair process after injury Myelinate CNS axons; provide a structural framework Maintain the blood-brain barrier; provide structural support; regulate ion, nutrient, and dissolved-gas concentrations; absorb and recycle neurotransmitters from scar tissue after injury Remove cell debris, wastes, and pathogens by phagocytosis Line ventricles (brain) and central canal (spinal cord); assist in producing, circulating, and monitoring cerebrospinal fluid Central Nervous System Ependymal cells Peripheral Nervous System
