Difference between Cerebellum and Cerebrum

Introduction

The entire nervous system of the human body is controlled by the brain that is the main part of the human body. The brain captured every piece of information sent by the sensory organs of the human body. After that, the collected vital information is returned to the muscles of the human body. There are three parts in the brain of the human body. They are forebrain, midbrain, and hindbrain. Cerebellum and cerebrum are the two parts situated into those parts which have so many differences. Every action of these two parts of the brain is so vital and has its own importance.

The Cerebellum and its Structure

The cerebellum is the second hugest section of the human brain and this part is so vital for the human body. This section contains almost 11% of the weight of the brain. This part also has two hemispheres. They are outer grey matter and inner white matter. This part is situated in the back side of the human brain. These hemispheres of the cerebellum have three parts − anterior, posterior, and flocculonodular.

The field of the cerebellum’s hemisphere is formed by the grey matter that is named cerebral cortex. This part helps in processing and recognition. The deeper part of the human brain is formed with white matter. This part is formed with glial cells and myelinated axons. Cerebellum is located in the hindbrain that is generally liable for coordinating voluntary movements. The other functions of the cerebellum are balance, posture, and coordination.

The Cerebrum and its Structure

Cerebrum is the largest section of the human brain. This part is situated in the forebrain. The cerebrum is naturally divided into two parts. The parts are right hemisphere and left hemisphere. It contains almost 80% of the weight of the human brain.

Cerebrum is divided into two sections, the left hemisphere and right hemisphere. Again two hemispheres are parted into two halves. These halves hold a lobe each. They are –

• Frontal lobe − This is the very first section of the brain. It responds to personal traits and characteristics. This part also works in odour procession and recognition.

• Parietal lobe − This part helps to form spatial relationships and explains sensation and pain.

• Temporal lobe − This part helps to capture muscle rhythm, short-term memory, and speech. This part presents beside every hemisphere.

• Occipital lobe − The location of this part is behind the brain. It works with processing vision.

Similarities of Cerebellum and Cerebrum

The Cerebellum and Cerebrum have so many differences; however, there are also some similarities between the Cerebellum and Cerebrum.

• Both the parts of the brain have the power to regulate the movement and motor process.

• Both also have the power in learning and memory consolidation.

• Both parts connect with the thalamus and the colliculi of the human brain.

• These two parts are parted into two hemispheres.

• Both parts hold the grey matter and white matter.

Differences between Cerebellum and Cerebrum

The key differences between the Cerebrum and the Cerebellum are discussed below.

Cerebellum	Cerebrum
This part is the largest just after the cerebrum.	This part of the brain is the most huge section of the human brain.
This part is situated in the hindbrain.	This part is situated in the forebrain.
This part of the brain parted into two hemispheres and presents a medial vermis.	This part also contains two hemispheres. They are parted into four lobes like frontal, parietal, temporal, and occipital.
The functions of the cerebellum are motor coordination, maintenance, balance, and posture.	The functions of the cerebrum are motor, sensory and higher mental works.
This part of the brain is not connected with memory always.	This part of the brain is always directly connected with the brain.
Cerebellum holds almost 50% of the neurons of the human brain.	The cerebrum holds a lesser amount of the neurons of the human brain.
In the location of the cerebellum, white matter produces arbor vitae.	In this part of the brain, the white matter cannot form arbor vitae.
This part of the brain holds almost 80% of the weight of the human brain.	This part of the brain holds about 11% of the weight of the human brain.
The cerebellum is situated just beneath the cerebrum and the backside of the above section of the brain stem.	The cerebrum is situated above the cerebellum and in the front section of the brain stem.

Conclusion

The actions that occur at every moment in the human body are also controlled by the brain. The brain has three sections. Cerebellum and the cerebrum are the two parts of them that are located in different sections. Both parts have various functions and are parted into different sections. They also have some similarities in their functions and structures. Cerebellum is also named the little brain is the most vital part of the human brain. This part of the brain regulates balance, posture and motor coordination of the human brain. The cerebrum is also the significant part that regulates the motor, sensory and higher mental works. Every human being needs to protect and maintain every part of the brain.

FAQs

Q 1. How are the injuries caused to the brain?

Ans. Brain injury is actually a traumatic brain injury, because the brain is the most vital part of the human body, any type of injury to the brain affects the other body functions. There are some other situations like cancer, strokes, and encephalitis also injured the function of the human brain.

Q 2. What can anyone do to protect to cerebellum?

Ans.One must have to protect every part of the body like the cerebellum. The methods to protect the cerebellum are regularly one must do exercises, a balanced diet must need to follow for everyone, and of course, one must need to avoid drinking and smoking.

Q 3. What parts of the body are controlled by the cerebellum?

Ans. The cerebellum is situated in the back part of the brain that regulates the balance, posture. In addition, the motor coordination of the human body is also maintained by this part.
