Question 3

In comparing the action of oligodendrocytes and Schwann cells

A) Myelin sheaths produced by Schwann cells are associated with a basal lamina, whereas those produced by oligodendrocytes have no such association
B) Oligodendrocyte cytoplasm is retained within the myelin sheath while Schwann cell cytoplasm is not trapped
C) Processes of the oligodendrocytes contact the node of Ranvier in the central nervous system whereas astrocyte processes contact the node in the parasympathetic nervous system
D) Schwann cells myelinate several axons, while oligodendrocytes myelinate only a single axon
E) The cell body of an oligodendrocyte is more closely associated with its myelin sheath than the cell body of a Schwann cell is with its myelin sheath
