Answer:
The correct option is c. The elevated ridges of tissue on the surface of the cerebral hemispheres are known as gyri while the shallow grooves are termed sulci.
Explanation:
The brain consists of many elevated ridges of tissue and grooves. Gyri are parts of the brain that are collected in the form of a crease between the grooves of the cortex. On the lateral face (external face) of the cerebral hemiferium. It appears as a wrinkled surface where there are folds (gyri) separated by indentations or shallow grooves (sulci). On this face it is possible to distinguish four large regions or lobes whose names relate to the cranial bones that cover them. They are the lobes: frontal, parietal, temporal and occipital.
Sulci and the gyri are part of the nervous system. In cerebral hemispheres the elevated ridges are gyri and the shallow grooves are sulci.
Gyri and sulci are the indentations and folds of the brain and make the brain structure look wrinkled. Sulci are the indentation or grooves that split the parts of the cerebral cortex.
Gyri is the bumps and the ridges of the folds that form the elevated structures on the cerebral hemispheres and the grooves of the cortex.
Therefore, option a. sulci and gyri are the shallow grooves and the elevated ridges.
