Sample White Matter of the Brain MCQs with answers
Sample MCQ #1
A patient presented with complaints of unable to learn to perform new tasks that require interdependent movement of each hand. On examination eye movements remain coordinated. His relatives noticed unusual behaviors concerning speech and object recognition . He is diagnosed with split-brain syndrome following an experimental brain surgery to manage severe epileptic seizures. Which fibres constitute the surgically resected structure?
AProjection fibers
BCommissural fibers
CShort association fibers
DLong association fibres
Show Answer & Explanation ▾
✓ Correct Answer: B. Commissural fibers
The given clinical scenario of split-brain syndrome is a type of disconnection syndrome following corpus callosotomy. Commissural fibres constitute the surgically resected structure i.e. the corpus callosum. Corpus callosotomy is a procedure where the corpus callosum is resected as a last resort to manage intractable epileptic seizures. The resultant predicament is that the patient would behave in some ways as if it were two separate minds.

Sample MCQ #2
The habenular commissure is located in the
ASplenium of corpus callosum
BSuperior lamina of pineal gland
CInferior lamina of pineal gland
DLamina terminalis
Show Answer & Explanation ▾
✓ Correct Answer: B. Superior lamina of pineal gland
The habenular commissure is located in the superior lamina of the pineal gland. The locations of the commissural fibers are: Corpus callosum- Medial surface of the brain Anterior commissure- Beneath the rostrum of the corpus callosum Posterior commissure- In the inferior lamina of the pineal gland Habenular commissure- In the superior lamina of the pineal gland Hippocampal commissure- Between the right fornix and the left fornix Reference : Textbook of Gray's Anatomy for students, 3rd Edition, Head and neck, Page number - 841
Sample MCQ #3
Which cell of brain produce myelin?
AAstrocytes
BOligodendrocytes
CMicroglia
DEpendymal cells
Show Answer & Explanation ▾
✓ Correct Answer: B. Oligodendrocytes
Oligodendrocytes, which produce myelin, exhibit a limited spectrum of specific morphologic changes in response to various injuries. In progressive multifocal leukoencephalopathy, viral inclusions can be seen in oligodendrocytes, with a smudgy, homogeneous-appearing enlarged nucleus.
