The elevated ridges of tissue on the surface of the cerebral hemispheres are known as while the shallow grooves are termed a. sulci; gyri. b. tracts; ganglia. c. gyri; sulci. d. receptors; effectors.

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.
