Satellite Cells In Pns Function

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 in pns function.

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. Schwann cells provide myelination to peripheral neurons. Glia are critical elements in the normal cns and pns. They also perform phagocytic functions and clear cellular debris allowing for the regrowth of pns neurons.

Researchers have yet to determine the specific functions of satellite cells but it is generally assumed that they help regulate and stabilize the. Satellite cells indicated by red arrows. Recent investigations indicate that the various. Satellite cells are found in the peripheral nervous system however as opposed to astrocytes which are found in the central nervous system.

Their role is not fully understood but it is thought they provide nutrient support and protection. The pns has two kinds of neuroglia. 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. Functionally the schwann cells are similar to oligodendrocytes of the cns.

Schwann cells and satellite cells. 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. Glial cells that surround some neurons in the peripheral nervous system. Each cns neuron is supported by 10 50 glial cells.

A mononuclear undifferentiated cell that is found in skeletal muscle fibers and promotes their growth repair and regeneration.
