Question:
Lateral sulcus separates \rule{2cm{0.15mm} .}
Lateral sulcus separates \rule{2cm{0.15mm} .}
Show Hint
Key mapping:
Central sulcus $\rightarrow$ Frontal vs Parietal
Lateral sulcus $\rightarrow$ Temporal vs (Frontal + Parietal)
Lateral sulcus $\rightarrow$ Temporal vs (Frontal + Parietal)
Updated On: May 8, 2026
- frontal lobe from parietal lobe
- parietal lobe from occipital lobe
- temporal lobe from frontal and parietal lobes
- parietal lobe from occipital and frontal lobes
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept: The cerebral cortex is divided into different lobes by grooves called sulci.
• Central sulcus: Separates frontal and parietal lobes
• Lateral sulcus (Sylvian fissure): Separates temporal lobe from frontal and parietal lobes
• Parieto-occipital sulcus: Separates parietal and occipital lobes
Step 1: Understand lateral sulcus.
It is a deep groove on the lateral surface of the brain.
Step 2: Identify structures separated.
It separates the temporal lobe (below) from frontal and parietal lobes (above).
Step 3: Analyze options.
• (A) Incorrect — central sulcus does this
• (B) Incorrect — parieto-occipital sulcus
• (C) Correct
• (D) Incorrect
Step 4: Conclusion.
Thus, lateral sulcus separates temporal lobe from frontal and parietal lobes. Final Answer: Option (C)
