The Nervous System: Central & Peripheral MCQs are important for gaining an understanding of how the human body handles information, regulates behavior, and controls actions. In CSS Competitive Exams, this section evaluates applicants’ knowledge of the CNS structure, function, and role and the PNS structure, function, and role. The nervous system performs cognitive functions, motor control, and sensory perception, and thus is a core subject matter in CSS psychology-related MCQs. Aspirants become proficient in understanding neurobiology, brain functions, and neural communication through this subject.
Central Nervous System (CNS): Brain and Spinal Cord
The CNS is made up of the brain and spinal cord, which regulate thought processes, emotions, and voluntary and involuntary functions. The brain is further divided into various parts: the cerebrum governs higher-order functions such as reasoning and memory, the cerebellum governs balance and coordination, and the brainstem governs essential activities such as breathing and heart rate. The spinal cord functions as a connection link between the brain and the body. In CSS Psychological Assessment MCQs, applicants can be examined on brain lobes (occipital, parietal, temporal, frontal), functions of neurotransmitters, and consequences of CNS damage.
Peripheral Nervous System (PNS): Somatic and Autonomic Divisions
The PNS links the CNS to the remainder of the body, the somatic and autonomic nervous systems. The somatic nervous system governs voluntary movement and sensory processing, whereas the autonomic nervous system (ANS) controls involuntary functions such as heart rate and digestion. The ANS is also divided into the sympathetic system (fight-or-flight functions) and the parasympathetic system (rest-and-digest processes). In CSS Psychology MCQs, questions can be related to neural pathways, reflex actions, nervous system diseases (e.g., multiple sclerosis, Parkinson’s disease), and nerve involvement in behavior. Free flashcards and CSS psychology quizzes on the nervous system improve examination preparation and conceptual understanding in neurophysiology and human behavior.
