GENERAL HISTOLOGY

Detailed explanation-1: -The cerebrum is the largest part of the brain, accounting for 85 percent of the organ’s weight. The distinctive, deeply wrinkled outer surface is the cerebral cortex. It’s the cerebrum that makes the human brain-and therefore humans-so formidable.

Detailed explanation-2: -The cerebrum makes up 85% of the brain’s weight, and the brain makes up about 2% of a human’s body weight. The texture of the brain is like a firm jelly. The heaviest normal human brain weighed 4.43 pounds.

Detailed explanation-3: -The cerebral cortex is the outer layer of the cerebral hemispheres. The cerebrum (or forebrain) makes up 75% of the brain by volume and 85% by weight. About 75% of all the brain’s neurons are located in the cerebral cortex, mainly in the grey matter.

Detailed explanation-4: -The preponderance of the cerebral cortex (which, with its supporting structures, makes up approximately 80 percent of the brain’s total volume) is actually a recent development in the course of evolution.

Detailed explanation-5: -An often cited argument in favor of the uniqueness of the human brain is its relatively large cerebral cortex, which accounts for 82% of brain mass.
