• A. 1. Cytons 2. Gyri 3. Sulci 4. Cerebral cortex
• B. 1. Gyri 2. Sulci 3. Cerebral cortex 4. Cytons
• C. 1. Sulci 2. Cerebral cortex 3. Cytons 4. Gyri
• D. 1. Cerebral cortex 2. Cytons 3. Gyri 4.Sulci

Answer 1

The correct option is D

1. Cerebral cortex 2. Cytons 3. Gyri 4.Sulci

Cerebrum is the major part of the forebrain. Deep median fissure divides the cerebrum into two equal cerebral hemispheres.The thin layers of cells cover the cerebral hemispheres called cerebral cortex, it is grey due to the presence of cytons and are thrown into prominent folds.The elevated ridges of tissue on the surface of the cerebral cortex are known as gyri while the shallow grooves are termed sulci.
