Question

Cerebral cortex is highly folded due to elevations and depressions on it. The elevations are called _________

• A. funiculi
• B. fovea
• C. gyri
• D. sulci

Hint:

Gyri increase cortical surface area and enhance cognitive capacity.

Answer 1

The Correct Option is C

Step 1: Understanding cerebral cortex structure.
The cerebral cortex has a folded surface to increase surface area for higher brain functions.

Step 2: Differentiating folds.
The raised folds of the cerebral cortex are called gyri, while the grooves or depressions are called sulci.

Step 3: Eliminating incorrect options.
Funiculi are bundles of nerve fibres in the spinal cord.
Fovea is a depression in the retina of the eye.

Step 4: Conclusion.
Hence, the elevations of the cerebral cortex are called gyri.
