Anatomy of Spinal Cord – Hard Case Based MCQs

Advanced clinical scenario based MCQs covering ascending tracts, descending tracts, UMN LMN pathways, grey matter nuclei and spinal cord lesions.

1. A patient presents with loss of vibration and proprioception in both lower limbs with preserved pain sensation. Lesion is most likely in:

Lateral spinothalamic tract Anterior horn Fasciculus gracilis Corticospinal tract

2. A hemisection of spinal cord at T10 causes ipsilateral loss of motor power due to damage of:

Spinothalamic tract Dorsal column Lateral corticospinal tract Spinocerebellar tract

3. Bilateral loss of pain and temperature over shoulders with preserved touch indicates lesion of:

Posterior columns Anterior white commissure Clarke’s column Dorsal root ganglion

4. Clarke’s column gives rise to which pathway?

Anterior spinothalamic Posterior spinocerebellar Corticospinal Rubrospinal

5. Which tract decussates twice before reaching its final destination?

Lateral corticospinal Posterior spinocerebellar Anterior spinocerebellar Dorsal column

6. A lesion affecting only anterior horn cells will cause:

Spastic paralysis Loss of pain sensation Flaccid paralysis Ataxia

7. Which tract carries crude touch?

Fasciculus cuneatus Lateral spinothalamic Anterior spinothalamic Spinocerebellar

8. Upper motor neuron lesion below the level of decussation produces:

Ipsilateral flaccid paralysis Contralateral spastic paralysis Ipsilateral spastic paralysis Contralateral sensory loss only

9. Loss of unconscious proprioception from lower limb occurs due to damage of:

Fasciculus gracilis Posterior spinocerebellar tract Lateral spinothalamic Rubrospinal

10. Intermediolateral cell column is concerned with:

Somatic motor Parasympathetic outflow only Sympathetic outflow Sensory relay
