Which anatomical structures constitute the peripheral nervous system (PNS)?

Correct answer is B. The peripheral nervous system (PNS) comprises nerves, ganglia, and sensory receptors. Nerves facilitate communication between the central nervous system (CNS) and the rest of the body, ganglia are clusters of nerve cell bodies, and sensory receptors detect stimuli. Options (a), (c), and (d) refer to structures associated with the central nervous system (CNS) or other parts of the CNS but are not specifically part of the peripheral nervous system. Understanding the components of the PNS is essential for comprehending how the nervous system interacts with the external environment and coordinates responses to stimuli.
