Question

Which of these neuroglial cells forms the myelin sheath in the central nervous system?
A) astrocytes
B) oligodendrocytes
C) Schwann cells
D) ependymal cells
E) satellite cells

Accepted Answer

Oligodendrocytes form the myelin sheath in the central nervous system, while Schwann cells form the myelin sheath in the peripheral nervous system. Astrocytes are involved in support and maintenance of nerve cells, ependymal cells produce and circulate cerebrospinal fluid, and satellite cells support and protect neuron cell bodies in ganglia.
