Final answer:
The two types of supporting cells in the PNS are satellite cells and Schwann cells.
Step-by-step explanation:
The two types of supporting cells in the peripheral nervous system (PNS) are satellite cells and Schwann cells.
Satellite cells are found in sensory and autonomic ganglia, where they surround the cell bodies of neurons.
They provide support and perform similar functions to astrocytes in the central nervous system (CNS).
Schwann cells, on the other hand, insulate axons with myelin in the periphery. They wrap around a portion of one axon segment and are responsible for creating individual segments of myelin sheaths.
