Question:
Cerebral cortex is highly folded due to elevations and depressions on it. The elevations are called _________
Cerebral cortex is highly folded due to elevations and depressions on it. The elevations are called _________
Show Hint
Gyri increase cortical surface area and enhance cognitive capacity.
Updated On: Mar 6, 2026
- funiculi
- fovea
- gyri
- sulci
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
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.
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.

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