Difference Between Cerebellum And Cerebrum

The brain is the most complex part of the body that acts as the command center for our entire nervous system. The information is picked up by sensory organs is processed by the brain, and the necessary information is sent back to the muscles. The brain in our body controls actions even breathing. Our brain is made up of three sections.

  • Forebrain
  • Midd-brain
  • Hindbrain

The cerebrum is the largest part of the forebrain. The cerebrum is further divided into four lobes, the right hemisphere, and the left hemisphere. The cerebellum is the section of the brain which coordinates sensory input with muscular responses, located just below and behind the cerebral hemispheres and above the medulla oblongata.

On the other hand, the cerebellum is the section of the brain that makes the muscles react to sensory stimuli. It also responds quickly to an external danger signal and sends the signal to the brain to react quickly and the reaction occurs. Its basic function is to coordinate the sensory and motor pathways.

Cerebrum vs Cerebellum – Overview

Both constitute the major part of our brain. The cerebrum is responsible for 84.5% of the brain’s weight. It is present in the forebrain. The cerebrum controls voluntary movements, memory functions, etc. On the contrary, the cerebellum sits closely under the cerebrum in our hindbrain and it is the second-largest section of the brain.

What is the Cerebrum and what is its major functions?

The cerebrum is the interior section/part of the brain of vertebrates, consisting of two lateral hemispheres joined by a thick band of fibers: the dominant part of the human brain. The cerebrum is associated with intellectual function, emotion, and personality. The brain is considered as a whole. It consists of left and right hemispheres: in People, it is the largest section of the brain and is believed to control conscious and voluntary processes. The cerebrum also controls voluntary movements and coordinate mental actions. A further division of the cerebrum called the central sulcus divides the two hemispheres into two halves. These halves contain a lobe each and are responsible for some important functions that are as follows.

  • Frontal Lobe
  • Parietal Lobe
  • Temporal Lobe
  • Occipital Lobe

The frontal lobe is present at the very front of the brain and is responsible for personality traits and characteristics which helps in smell procession and recognition. The parietal Lobe helps in establishing spatial relationships and interprets sensation and pain. This lobe is situated near the middle part. While, the temporal lobe is responsible for short-term memory, speech, and musical rhythm and sits at the edges of each hemisphere. At last, the occipital lobe is associated with processing vision that is situated at the back of the brain.

The cerebrum also operates with certain types of neurons:

  • Sensory-neurons
  • Motor-neurons
  • Inter-neurons

WHAT is the Cerebellum?

The cerebellum is the part of the central nervous system. The cerebellum is the largest part of the brain after the brain. It is located in the back and lower part of the skull. The cerebellum is consists of two hemispheres in the center of which there is a small cavity called the Vermis. This narrow structure is shaped like a worm. There the unconscious nerve pathways lodge or side.

Cerebellum Function

  • The main function of the cerebellum is to coordinate the sensory and motor pathways.
  • It also makes the muscles react to sensory stimuli. It responds or reacts quickly to an external danger signal and sends the signal to the brain to react quickly and various reactions occur.
  • The cerebellum receives data or information and orders from the cerebral cortex and connects them with the locomotor system.
  • It also serves many functions such as processes of memory, language, attention, learning, among other functions.
  • So, the cerebellum is not responsible for any of the functions of the olfactory system.

Difference Between Cerebellum And Cerebrum In Tabular Form

Cerebellum

Cerebrum

Located at the hindbrain. Located n the forebrain.
The cerebellum is divided into two hemispheres. It is also divided into two hemispheres that are further divided into 2 sections.
Its major functions are motor coordination, posture maintenance, and balance. Its major functions are sensory, motor, and higher mental functions.
Smaller than the cerebrum. The largest section of the central nervous system.
Not always associated with memory. Also associated with memory.
The main function of the cerebellum is to coordinate the sensory and motor pathways. The cerebrum is associated with intellectual function, emotion, and personality.
It also makes the muscles react to sensory stimuli. It responds or reacts quickly to an external danger signal and sends the signal to the brain to react quickly and various reactions occur. The cerebrum also controls voluntary movement, intelligence, and memory
