Question: Are Satellite Cells In The CNS Or PNS?

The PNS has two kinds of neuroglia: schwann cells and satellite cells.

Schwann cells provide myelination to peripheral neurons.

Functionally, the schwann cells are similar to oligodendrocytes of the CNS.

Satellite cells are small glia that surround neurons’ sensory ganglia in the ANS.

Are satellite cells in the CNS?

Satellite glial cells are glial cells that cover the surface of nerve cell bodies in sensory, sympathetic, and parasympathetic ganglia. 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 the embryo during development.

Are astrocytes in the CNS or PNS?

In the central nervous system, glia develop from the ventricular zone of the neural tube. These glia include the oligodendrocytes, ependymal cells, and astrocytes. In the peripheral nervous system, glia derive from the neural crest. These PNS glia include Schwann cells in nerves and satellite glial cells in ganglia.

What are 4 types of Neuroglia in the CNS?

The four types of neuroglia found in the central nervous system are astrocytes, microglial cells, ependymal cells, and oligodendrocytes. The two types of neuroglia found in the peripheral nervous system are satellite cells and Schwann cells.

Where are satellite cells located?

Skeletal muscle satellite cells are quiescent mononucleated myogenic cells, located between the sarcolemma and basement membrane of terminally-differentiated muscle fibres.
