Multiple Choice
Which of the following neuroglial cell types is found in the peripheral nervous system (PNS)?
A
Oligodendrocytes
B
Astrocytes
C
Schwann cells
D
Microglia
Verified step by step guidance1
Understand the distinction between the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord, while the PNS includes all the nerves outside the CNS.
Learn about neuroglial cells and their roles. Neuroglial cells provide support, protection, and insulation for neurons. Different types of neuroglial cells are specialized for either the CNS or PNS.
Review the neuroglial cell types listed in the problem: Oligodendrocytes, Astrocytes, Schwann cells, and Microglia. Note that Oligodendrocytes and Astrocytes are specific to the CNS, while Schwann cells are specific to the PNS.
Understand the function of Schwann cells in the PNS. Schwann cells produce the myelin sheath that insulates axons in the PNS, facilitating faster transmission of nerve impulses.
Conclude that Schwann cells are the correct answer because they are the neuroglial cell type found in the peripheral nervous system (PNS).
