Nervous System Multiple Choice Questions and Answers Questions
Question 1 of 5
Concerning the electroencephalogram (EEG):
Correct Answer: C
Rationale: Alpha waves are occipital (not temporal, A), beta waves are fast (not slow, B), theta waves are 4-7 Hz (C, correct), and EEG aids but isn’t 100% diagnostic (D). C is correct.
Question 2 of 5
Brodmann's areas map different regions of the to particular functions.
Correct Answer: B
Rationale: Brodmann’s areas map the cerebral cortex (B) to functions (e.g., area 4 for motor, 17 for vision). The cerebellum (A) has no Brodmann areas, basal forebrain (C) is subcortical, and corpus callosum (D) is white matter. B is correct.
Question 3 of 5
Which ganglion is responsible for cutaneous sensations of the face?
Correct Answer: D
Rationale: The trigeminal ganglion (D) (cranial nerve V) relays cutaneous sensations from the face. Otic (A) is autonomic (salivary), vestibular (B) is balance, and geniculate (C) is taste/facial. D is correct.
Question 4 of 5
Which functional division of the nervous system would be responsible for the physiological changes seen during exercise (e.g., increased heart rate and sweating)?
Correct Answer: B
Rationale: The autonomic nervous system regulates involuntary functions like heart rate and sweating, which increase during exercise. The somatic system controls voluntary movements, the enteric system governs digestion, and the central nervous system (CNS) includes the brain and spinal cord but isn’t a functional division in this context.
Question 5 of 5
Which of these locations is where the greatest level of integration is taking place in the example of testing the temperature of the shower?
Correct Answer: D
Rationale: The cerebral cortex is responsible for the highest level of sensory integration, processing, and decision-making, such as interpreting shower temperature and deciding to adjust it. The thalamus relays signals, the spinal cord handles reflexes, and skeletal muscle executes commands.
