What is the Largest Part of the Brain?

Our brain is located in our head where it is caged within the skull. The skull is made up of a hard and flat bone which serves as the brain’s foremost protection. Our brain is composed of different parts. Each part is designed to perform a specific role. These roles are highly essential in maintaining our life and making us survive every second. An adult human brain weighs approximately 1,300 grams. This is roughly 2% of the total body weight of an average adult person. This is the reason why it is also considered as one of the largest organs in the body. But what is the largest part of the brain?

In terms of its size and weight, the cerebrum comprises the largest part of our brain. The cerebrum is basically 85% of the total weight of the brain which means it weighs roughly around 1,100 grams. The cerebrum is located superior or on top of the brain stem and cerebellum. It is grayish-pink in color and exhibits a rough and wrinkled surface called the gyri. These gyri are considered as an indicator at how effective our cerebrum is. The more gyri formation, the better the cerebrum functions.

The cerebrum is also further subdivided into smaller parts. This is separated by a fissure that divides the left cerebral hemisphere and the right cerebral hemisphere. Each hemisphere is designed to control the opposite side of the body. The cerebrum is also composed of four distinct lobes namely the frontal lobe, the parietal lobe, the temporal lobe and the occipital lobe. The frontal lobe is the one responsible for the voluntary motor coordination. This is the region why we are capable of reasoning and feeling different emotions. The parietal lobe is located at the upper region of the brain and aids in our touch perception. The third part is the temporal lobe which is found at the sides of the brain near the ears which is why it helps in our auditory functioning as well as the olfactory or smell perception. The occipital lobe, on the other hand, is located at the back of the head and is the one controlling our sense of sight.
