Cerebrum & Cortex

1.A 60 year old person who was suffering from high blood pressure was admitted to the hospital with sudden onset of contra lateral hemiplegia and loss of speech. Based on your knowledge of anatomy answer the following questions: • Which part of the brain is probably involved here • Describe the sulci, gyri and functional areas on the superolateral surface of cerebrum • Describe the blood supply of this surface

1.Lateral ventricle of brain

2.Functional areas of supero-lateral surface of cerebrum

3.Arterial supply of Cerebrum

4.Classify white matter fibres of cerebrum with suitable examples. Add a note on fibres of internal capsule

5.Classify white matter of the brain with an example of each. Describe the white matter bundle seen in the median longitudinal cerebral fissure

6.Describe the Sulci, Gyri, functional areas and blood supply on the superolateral surface of cerebrum

7.Association fibres of the cerebrum

8.Describe the Functional areas and Blood supply of Superolateral surface of Cerebral hemisphere

9.Parts, boundaries and features of lateral ventricle

10.Arterial supply and venous drainage of cerebral cortex

1.Basal nuclei of cerebrum

2.Broca’s area

3.Lateral sulcus of cerebrum

4.Fornix of brain

5.Pre central gyrus of cerebrum

1.Sulci and Gyri of superolateral surface of cerebral hemisphere. Name the following

2.Nucleus receiving taste sensation

3.Broadmann’s area for auditory cortex

4.Name two complete sulci of cerebrum

5.Two features in the floor of inferior horn of lateral ventricle

6.Blood supply of medial surface of cerebrum

7.Blood supply of cerebrum – inferior surface

8.Supero-lateral surface of cerebral hemisphere

9.Visual cortex

1.Assertion: The Broca’s area is located in the lower part of precentral gyrus

• Reason: A lesion in the Broca’s area will cause motor aphasia
• a) Both A and R are true and R is the reason for A
• b) Both A and R are true and R is not the reason for A
• c) A is correct but R is incorrect
• d) A is incorrect but R is correct

2.True about lateral ventricle of brain are

• 1) Develops from diencephalon 2) Communicates with third ventricle through foramen of magendie
• 3) Inferior horn extends into the temporal lobe
• 4) Calcar avis is a feature in the posterior horn
• a) 2, 3, 4
• b) 1, 3
• c) 3, 4
• d) 1, 2, 3
