Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which sulcus in the lateral surface of the cerebral cortex separates the frontal and temporal lobe rostrally?
A
Lateral fissure of Sylvius
B
Central sulcus of Rolando
C
Lateral cingulate sulcus
D
Fronto-Temporal sulcus
Explanation: 

Detailed explanation-1: -The lateral sulcus is a deep fissure that is first identified on the inferior surface of the brain close to the anterior perforated substance but becomes most visible on the lateral surface where it separates the frontal and parietal lobes from the temporal lobe.

Detailed explanation-2: -In neuroanatomy, the lateral sulcus (also called Sylvian fissure, after Franciscus Sylvius, or lateral fissure) is one of the most prominent features of the human brain. The lateral sulcus is a deep fissure in each hemisphere that separates the frontal and parietal lobes from the temporal lobe.

Detailed explanation-3: -Examination of the lateral surface of the brain will reveal the lateral sulcus (the Sylvian fissure). This groove separates the temporal lobe from the parietal lobe.
