Satellite Cells Cns Or Pns

They may contribute to chronic pain.

Satellite cells cns or pns.

Schwann cells neurolemma of the pns mirror the role of oligodendrocytes in the central nervous system. Carries sensory information from pns sensory receptors to cns. Satellite cells are found in the peripheral nervous system however as opposed to astrocytes which are found in the central nervous system. Satellite glial cells or satellite cells formerly called amphicytes are glial cells that cover the surface of neuron cell bodies in ganglia of the peripheral nervous system thus they are found in sensory sympathetic and parasympathetic ganglia.

Macroglia contained in the peripheral nervous system are satellite glial cells schwann cells and enteric glia. Satellite cells schwann cells. Central nervous system and peripheral nervous system. The neurons that have satellite cells make up something called gangila which are.

These resemble the astrocytes of the cns and assist in regulating the external chemical environment. Functionally the schwann cells are similar to oligodendrocytes of the central nervous system cns. Glia also called glial cells or neuroglia are non neuronal cells in the central nervous system brain and spinal cord and the peripheral nervous system that do not produce electrical impulses. Satellite cells are small flattened cells found in the ganglia of the peripheral nervous system ganglion collection of cell bodies.

Researchers have yet to determine the specific functions of satellite cells but it is generally assumed that they help regulate and stabilize the environment around ganglion cell bodies. Largest and most numerous produce feet projections that surround blood vessels. Enteric glial cells. In the central nervous system glial cells include oligodendrocytes astrocytes ependymal cells and microglia.

Similar to oligodendrocytes in the central nervous system schwann cells myelinate neurons in the peripheral nervous system. Ependymal cns cell that form the linings. They maintain homeostasis form myelin and provide support and protection for neurons. Satellite cells play an important role in modulating the pns following injury and inflammation.

Recent investigations indicate that the various. They myelinate the axons of neurons and modulate extracellular fluid. Each cns neuron is supported by 10 50 glial cells. Satellite cells surround neurons in the sensory sympathetic and parasympathetic ganglia and help regulate the chemical environment.

Glia are critical elements in the normal cns and pns.
