Nervous System Multiple Choice Questions and Answers Questions
Question 1 of 5
The dorsal column tracts are concerned with:
Correct Answer: D
Rationale: Dorsal columns carry vibration (D, correct), position, and fine touch, not crude touch (A, spinothalamic), temperature (B, spinothalamic), or pain (C, spinothalamic). D is correct.
Question 2 of 5
Which primary vesicle of the embryonic nervous system does not differentiate into more vesicles at the secondary stage?
Correct Answer: B
Rationale: The embryonic brain forms three primary vesicles: prosencephalon, mesencephalon, and rhombencephalon. The prosencephalon divides into telencephalon and diencephalon, and the rhombencephalon into metencephalon and myelencephalon. The mesencephalon (B) remains undivided as the midbrain. B is correct.
Question 3 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 4 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 5 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.
