CNS and PNS MCQs
Our set of CNS and PNS multiple-choice questions (MCQs) explores into various facets of the CNS and PNS, exploring their structures, functions, and roles in regulating bodily functions.
If you’re preparing for an exam or aiming to deepen your understanding of neurobiology, these MCQs provide valuable learning opportunities for students and enthusiasts alike.
Let’s explore the MCQs below and broaden your knowledge of neuroscience!

The central nervous system (CNS) and peripheral nervous system (PNS) are integral components of the body’s nerve network. The CNS, consisting of the brain and spinal cord, serves as the core processing center, while the PNS encompasses all nerve structures beyond the CNS, including nerves, ganglia, and sensory receptors.
