Unformatted text preview: * Oligodendrocyte * Form myelin sheath around CNS neurons Central Nervous System Neuroglia * Microglia * Phagocytic cells that engulf destroy microbes and cellular debris in the CNS * active in response to inflammation or injury Microglia Astrocyte & Microglia Central Nervous System Neuroglia * Ependymal Cells- * Line the ventricles (spaces filled with CSF) of the brain and the central canal of the spinal cord Nervous System * Produce cerebrospinal fluid * Assist in the circulation of the CSF Peripheral Nervous System Neuroglia * Schwann cells (neurolemmocytes) Each cells produces part of the myelin sheath around a single axon in the PNS. * Neurolemma (sheath of Schwann)- the outer nucleated cyotplasmic layer of the neurolemmocyte. * Nodes of Ranvier (neurofibral nodes)- periodic gaps in the myelin sheath. Myelinated Axons Satellite Cells * surround the neuron cell bodies in ganglia of the PNS. Little is known of their function....
