A Complete Information About Important Areas of The Brain

areas of the brain

The brain is the controlling power in our body. It is the central processing unit of living organisms. As CPU in computers, Brain in Humans. The average weight of the human adult brain is 3 pounds. 60%  of the brain is made up of fat whereas the remaining percentage is full of water, proteins, carbohydrates, and salts. Glucose is the most wanted macromolecule that keeps your brain awake and functioning. The human brain is not a muscle. There are several blood vessels and neurons in our brain. It is one of the most complex and largest organs in our body. The brain controls all the internal and mental processes including communication, thinking, reading, processing, and planning, etc. there are different functional sections in the brain listed below along with their function.

The cerebrum is also called the front brain. It includes gray and white matter in the center region. It is the largest part of the brain. Cerebral is responsible for initiating and coordinating movements. Also it regulates temperature. Different parts of the cerebrum have different functions including speech, judgment, thinking, reasoning, problem-solving, etc. Also, it is responsible for vision, hearing, touch, and other specific senses.

Cerebral Cortex

It is the outer covering of the cerebrum. It includes gray matter. There are several folds and comprises in this cortex area giving it a large surface area. The weight of the cerebral cortex is half of the brain’s weight. There are two hemispheres right for controlling the left side body and the left controlling the right side body.


It is the connection between the cerebrum and the spinal cord. It includes:

Midbrain – It is a complex structure with different neuron clusters. It is responsible for hearing, movement, calculating responses, and environmental changes.

Pons – from the pons 12 cranial nerves originate. They are responsible for tear production, chewing, blinking, focusing vision, balance, hearing, and facial expression.

Medulla – it is the bottom of the brainstem and meeting point of the brain and spinal cord. It is essential for bodily activities, including heart rhythm, breathing, blood flow, and oxygen and carbon dioxide levels. The reflex activities like sneezing, vomiting, coughing, and swallowing are controlled by the medulla.


The size of the cerebellum is almost the size of our fist. It is located at the back of the head. It is situated below the temporal and occipital lobes and above the brainstem. There are two hemispheres: Outer containing neurons and Inner for communicating with the cerebral cortex. It helps in coordinating voluntary muscle movements. It is responsible for maintaining posture, balance, and equilibrium.

Lobes of Brain

Frontal Lobes – largest lobe responsible for personality, decision making, and movements, and speech ability.

Parietal Lobe – Middle lobe responsible for identifying objects, understanding spatial relationships, interpreting pain and touch, and spoken language.

Occipital Lobe – Is responsible for the vision and it is at the back of the brain.

Temporal Lobe – It is responsible for short-term memory, speech, musical rhythm, and smell recognition.


Thus the brain is an important organ in our body that is solely responsible for controlling the entire structure. From vision to speech, from reading to planning, every movement of our body is controlled by the brain. The brain is the controller and regulator of our body.
