Nervous System Multiple-Choice Questions 1. Which structure is responsible for transmitting sensory information from the peripheral nervous system to the central nervous system? A) Spinal cord B) Cerebrum C) Cerebellum D) Medulla oblongata Correct Answer: A) Spinal cord Explanation: The spinal cord serves as the major communication link between the PNS and the CNS, transmitting sensory information and integrating reflexes. 2. If a patient has damage to the lumbar plexus, which of the following areas would likely be affected? A) Upper limb movement B) Lower limb movement C) Facial sensation D) Vision Correct Answer: B) Lower limb movement Explanation: The lumbar plexus, originating from spinal nerves L1-L4, is responsible for innervating the lower limb, so damage here affects lower limb mobility. 3. During an emergency response, a reflex allows a person to pull their hand away from a hot surface without consciously thinking. What part of the nervous system initiates this response? A) Cerebrum B) Reflex arc C) Dorsal horn D) Thalamus Correct Answer: B) Reflex arc Explanation: The reflex arc is the smallest unit capable of initiating a response without conscious thought, allowing for quick, automatic reactions like pulling away from painful stimuli. 4. A patient exhibits loss of sensation in the medial thigh. Which nerve might be impaired? A) Obturator nerve B) Tibial nerve C) Ulnar nerve D) Radial nerve Correct Answer: A) Obturator nerve Explanation: The obturator nerve provides sensation to the medial thigh; damage to it could result in sensory loss in this area. 5. Which area of the brain is primarily involved in coordinating voluntary motor function and balance? A) Cerebellum B) Medulla oblongata C) Hypothalamus D) Cerebrum Correct Answer: A) Cerebellum Explanation: The cerebellum plays a critical role in motor coordination, balance, and the fine-tuning of voluntary movements.
