GROSS ANATOMY

Detailed explanation-1: -The longitudinal fissure separates the left and right cerebral hemispheres and the lateral sulcus is the border between the frontal and temporal lobes. Figure 23.13 A coronal section at the location of the amygdala.

Detailed explanation-2: -A fissure or groove that separates the two hemispheres is called the great longitudinal fissure.

Detailed explanation-3: -The two hemispheres of the cerebellum are separated by the longitudinal fissure. False; This fissure separates the cerebral hemispheres, not the cerebellar hemispheres. The cerebral hemispheres would fail to develop if the neural crests of the embryo were destroyed.

Detailed explanation-4: -The cerebral hemispheres are paired structures separated from each other by the longitudinal fissure along the midline. A mid-sagittal cut through the longitudinal fissure is used to produce two hemisected brains. Each cerebral hemisphere is organized into five lobes: frontal, parietal, occipital, temporal and insula.
