CNS & EYE BALL SAQ & MCQ suggestions

  1. 1. SAQ suggestions for CNS and EYEBALL 1. CSF- Def, formation, circulation, absorption, function. What is hydrocephalus? Types. 2. Spinal cord- Def tracts. Name various tracts of spinal cord. Draw and label cross section of spinal cord at mid-thoracic/mid-cervical level showing various tracts. Write down blood supply of spinal cord. Define UMN and LMN. Difference between UMN and LMN. What is Brown Sequard Syndrome? 3. Draw and label cross section of brain stem at the level of superior colliculus/inferior colliculus/pyramidal decussation. 4. Reticular formation-Def, function. 5. Cerebellum-Histological structure, morphological and functional divisions with functions. Name deep cerebellar nuclei. Short note on cerebellar syndrome, cerebellar peduncles. 6. Fourth ventricle-Floor 7. Cerebrum-Histological structure of cortex, Lobes-boundary, functional areas, their functions, effects of lesion, blood supply. Short note on white matter of cerebrum, corpus callosum. 8. Diencephalon-Parts, Thalamus-nuclei, functions. Hypothalamus-functions. 9. Basal nuclei-def, parts, function 10. Limbic system-Def, components, functions 11. Pyramidal tract-def, course, termination, function, effect of lesion. 12. Short note-Internal capsule, basal nuclei, BBB, BCB, circle of Willis. 13. Name refractive medias of eyeball. Layers of cornea, retina 14. Short note on aqueous humor, Horner’s syndrome, Argyll Robertson pupil. 15. Visual pathway, pathway of light reflex and accommodation reflex. What is direct and consensual light reflex? Effect of lesion of visual pathway.
  2. 2. MCQ CNS & EYEBALL Dr. Ashfaq 1. Brain stem includes- 6. Spinal cord is kept in position by- a midbrain a CSF b pons b filum terminale c cerebellum c ligamentum denticulatum d medulla oblongata d subdural capillary fluid e spinal cord e rostral continuity with medulla 2. Spinal cord- 7. Regarding pain from the limbs- a is located within whole vertebral canal a receptor is free nerve ending b presents primitive organization of grey b second order neurons lie in nucleus and white matter gracilis and cuneatus c is the part of hind brain c its relay occur in ventral posteromedial d has a uniform diameter nucleus of thalamus e contains nuclei of spinal accessory d it passes through anterior spinothalamic nerves tract e the ultimate goal is post central gyrus 3. Gray matter is composed of- 8. Sympathetic stimulation results in- a neuron a dilatation of pupil b microglia b reduction of heart rate c fibrous astrocyte c rise of blood pressure d capillaries d constriction of bronchi e lymph vessels e contraction of external anal sphincter 4.
