Neuroglia Notes NEUROGLIA Glia means “glue” Act in support, guiding development, and stimulation and maintenance TYPES OF NEUROGLIA IN CNS Astrocytes – star shaped cells with many processes hold neurons close to blood vessels help form the blood-brain barrier Oligodendrocyte most common form the myelin sheath for neurons of CNS Microglia – small, have fewer processes, and are phagocytes protect the CNS by phagocytizing microbes and clearing away debris from inflammation and tissue damage Ependymal cells form the cerebrospinal fluid (CSF) and also assist in its circulation NEUROGLIA OF PNS Schwann cells supply myelin sheathes to axons in the PNS Also aids in the regrowth of damaged peripheral axons Satellite cells flattened cells found around cell bodies of neurons in ganglia Ganglia = bunched up cell bodies in PNS
