Satellite Cells In Pns Function

Satellite cells indicated by red arrows.

Satellite cells in pns function.

Glial cells that surround some neurons in the peripheral nervous system. A mononuclear undifferentiated cell that is found in skeletal muscle fibers and promotes their growth repair and regeneration. They may also help to regulate the neuronal environment and be involved in neurotransmission. Recent investigations indicate that the various.

Glia are critical elements in the normal cns and pns. 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. Their role is not fully understood but it is thought they provide nutrient support and protection. The pns has two kinds of neuroglia.

Functionally the schwann cells are similar to oligodendrocytes of the cns. Both satellite glial cells sgcs and schwann cells the cells that ensheathe some nerve fibers in the pns are derived from the neural crest of. Satellite cells location structure and function satellite cells are small flattened cells found in the ganglia of the peripheral nervous system ganglion collection of cell bodies. Any of the cells that envelop the bodies of nerve cells within the peripheral nervous system.

Schwann cells provide myelination to peripheral neurons. Satellite cells main purpose appears to be regulation the environment around the neurons keeping chemicals in balance. Schwann cells and satellite cells. Satellite cells are found in the peripheral nervous system however as opposed to astrocytes which are found in the central nervous system.

Many types of glia may be found in the cns e g astrocytes microglia oligodendrocytes and pns schwann cells satellite glial cells each of which serves a distinct set of functions.
