Difference Between Cerebellum And Cerebrum

Cerebellum and Cerebrum are both parts of the brain. The anatomy of brain consists of various parts. The cerebellum and cerebrum both are the parts of brain that control various actions of the body. 80% of the human brain is comprised of cerebrum whereas 11% of brain is composed of cerebellum. Both are different in terms of their functions, size, location, etc. The below article covers the difference between Cerebellum and Cerebrum in detail.

Difference between Cerebellum and Cerebrum

Differences between Cerebellum and Cerebrum are as follows:

Characteristics	Cerebellum	Cerebrum
Functions	The main functions of cerebellum are coordination and regulation of posture, movement and balance.	The main functions of cerebrum are controlling the voluntary functions such as will power, memory and intelligence.
Size	The size of cerebellum is smaller than that of cerebrum.	The size of cerebrum is large than cerebellum as it is the largest part of central nervous system.
Part of	Cerebellum is the part of hindbrain.	Cerebrum is the part of forebrain.
Presence of cavity	Cerebellum has two cavities that are known as lateral ventricles.	Cerebrum has no presence of cavity.
Presence of hemisphere	Cerebellum has two cerebellar hemisphere that are connected to the brain stem.	Cerebrum has two cerebral hemisphere and each having four lobes.
Memory	The cerebellum is associated with memory in rare situations.	Cerebrum is always associated with the memory.
Fibres	In cerebellum the vermis connects two sides of hemisphere.	In cerebrum the corpus collosum connects two sides of hemisphere.
Formation of arbor vitae	In cerebellum the white matter present forms arbor vitae.	In cerebrum the white matter present does not form arbor vitae.
Number of neurons present	Cerebellum consists of more than 50% of total number of neutrons present in the brain.	Cerebrum consists of less number of neurons as compared to cerebellum.

What is Cerebellum?

Cerebellum is defined as a second largest part of the brain. Cerebellum is located below the posterior part of the cerebrum. Cerebellum consists of more than 50% of neurons that are present in brain. The upper part of cerebellum consists of grey matter and the central part consists of white matter. Cerebellum is also known as little brain. Cerebellum consists of two hemisphere and has a wrinkled surface like cerebrum.

Cerebrum is responsible for various important functions of the body such as coordination and regulation of posture, movement, balance etc. Cerebellum has two cavities that are known as lateral ventricles. It is present at the back of the brain. The cerebellum hemisphere has posterior, anterior and flocculonodular lobe.

What is Cerebrum?

Cerebrum is defined as the largest part of the brain. Cerebrum is present at in the upper cranial cavity of the brain. Cerebrum constitutes more than 80% of total brain. Cerebrum is divided by cerebrum fissure longitudinally into two parts named as left hemisphere and right hemisphere. These two hemispheres are connected to each other through corpus callosum.

The cerebral hemispheres are surrounded by white and grey matter within. Grey matter consists of various kinds of cells and white matter is made up of axons. Cerebrum is further partitioned into four segments namely parietal curve, cerebrum, fleeting curve and occipital curve. Cerebrum is responsible for controlling the voluntary functions such as will power, memory and intelligence.

FAQs on Cerebrum and Cerebellum

1. How we can Protect Cerebellum and Cerebrum?

Answer:

To keep our brain free from injuries is very important for mental as well as physical health. For protecting cerebellum, cerebrum and other parts of brain we must eat a healthy diet, exercise regularly, follow a healthy diet and to avoid drinking and smoking.

2. Which are the three types of Lobes present in Cerebellum?

Answer:

The three types of lobes present in cerebellum are:

1. Anterior lobe: Anterior lobe is responsible for sensing of the position of the body.
2. Posterior lobe: Posterior lobe is responsible for the coordination of muscles.
3. Flocculonodular lobe: Flocculonodular lobe is responsible for coordinating the eye and head movements.

3. Cerebellum is Developed Fully at which age?

Answer:

The total development of cerebellum takes place at age of 11.8 years in females whereas at the age of 15.6 in males.

4. What are the Components of Forebrain?

Answer:

The forebrain consists of three parts namely Thalamus, Hypothalamus and Cerebrum. Thalamus is at the right side and is responsible for transferring of tangible data. Hypothalamus is located below the thalamus and responsible for functions like getting driving forces from parts of the body, controlling of smell and taste related feelings etc. Cerebrum is responsible for controlling the voluntary functions such as will power, memory and intelligence.

5. Why Human Brain is more efficient than other Vertebrates?

Answer:

The number of neurons in the human brain are increased due to increases surface area of human brain through folded cortex. Therefore human brain is more efficient than other vertebrates.
