Oligodendrocytes Oligodendrocytes provide support to axons of neurons in the central nervous system, particularly those that travel long distances within the brain. They are involved in creating cerebrospinal fluid CSF. Radial glia : Radial glial cells are progenitor cells that can generate neurons, astrocytes and oligodendrocytes. Peripheral Nervous System Schwann cells : Similar to oligodendrocytes in the central nervous system, Schwann cells myelinate neurons in the peripheral nervous system.
Satellite cells : Satellite cells surround neurons in the sensory, sympathetic and parasympathetic ganglia and help regulate the chemical environment. They may contribute to chronic pain. Enteric glial cells : Enteric glial cells are found in the nerves in the digestive system.

Satellite cells perform a similar function to astrocytes, Key Terms myelin : A white, fatty material, composed of lipids and lipoproteins, that surrounds the axons of nerves. Neuroglia of the Peripheral Nervous System The two kinds of glia cells in the PNS, schwann cells and satellite cells; each have unique functions.
