Satellite Cells In Pns Function

They may also help to regulate the neuronal environment and be involved in neurotransmission.

Satellite cells in pns function.

Researchers have yet to determine the specific functions of satellite cells but it is generally assumed that they help regulate and stabilize the. They also perform phagocytic functions and clear cellular debris allowing for the regrowth of pns neurons. Recent investigations indicate that the various. The pns has two kinds of neuroglia.

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. A mononuclear undifferentiated cell that is found in skeletal muscle fibers and promotes their growth repair and regeneration. Their role is not fully understood but it is thought they provide nutrient support and protection. Glial cells that surround some neurons in the peripheral nervous system.

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. Schwann cells provide myelination to peripheral neurons. Satellite cells are found in the peripheral nervous system however as opposed to astrocytes which are found in the central nervous system. Each cns neuron is supported by 10 50 glial cells.

Functionally the schwann cells are similar to oligodendrocytes of the cns. 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. Glia are critical elements in the normal cns and pns. Satellite cells main purpose appears to be regulation the environment around the neurons keeping chemicals in balance.

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.
