Cerebrum vs. Cerebellum
Main DifferenceThe brain is a vital organ of our body. It is said as the control unit of the whole body. The brain has different parts in which cerebrum and cerebellum are included. The cerebrum is the principal and largest part of our brain. It comes in the forebrain. It is situated anteriorly in the cranial cavity of the skull. It consists of two hemispheres known as a left cerebral hemisphere and right cerebral hemisphere. It is concerned with the complex sensory and neural functions. It also controls and initiate the voluntary activities of the body and coordinates them with each other, whereas cerebellum is the part of the brain that lies posteroinferiorly. It comes in the hindbrain, and It is present at the back of the skull in the cranial cavity. Its function is to initiate and regulate the muscular activity in our body.
Difference Between Cerebrum and Cerebellum
Cerebrum vs. Cerebellum
The cerebrum is the part of the forebrain, whereas cerebellum is the part of the hindbrain.
Cerebrum vs. Cerebellum
The cerebrum is the center of the brain, while cerebellum is the center of the hindbrain.
Cerebrum vs. Cerebellum
The cerebrum is larger in size and makes most of the volume of the brain, whereas cerebellum is smaller in size and makes only 10% of total volume of the brain.
Cerebrum vs. Cerebellum
Cerebrum has four main lobes while cerebellum has three lobes.
Cerebrum vs. Cerebellum
The cerebrum is though larger in size, but it has less number of neurons than cerebellum, cerebellum contains 50% of all neurons of the total brain.
Cerebrum vs. Cerebellum
The cerebrum controls voluntary functions, speech, , on the other hand, the cerebellum is involved in coordinated voluntary movements and equilibrium.
Cerebrumnoun
(neuroanatomy) The principal and most anterior part of the brain in vertebrates, which is located in the front area of the skull and divided into two hemispheres, left and right, separated by a fissure. In humans it is the largest part of the brain and is responsible for the integration of complex sensory functions and the initiation and coordination of voluntary activity, and the higher mental functions such as consciousness, thought, reason, emotion, and memory.
Cerebellumnoun
(neuroanatomy) Part of the hindbrain in vertebrates. In humans it lies between the brainstem and the back of the cerebrum and is formed of two lateral lobes and a median lobe. It plays an important role in sensory perception, motor output, balance and posture.
Cerebrumnoun
anterior portion of the brain consisting of two hemispheres; dominant part of the brain in humans
Cerebellumnoun
a major division of the vertebrate brain; situated above the medulla oblongata and beneath the cerebrum in humans

What is Cerebrum?
The cerebrum is the largest, major and the most prominent part of our brain and it is situated anteriorly in the cranial cavity of the skull. The cerebrum is the center part of the forebrain, and its weight is 4/5th of the total weight of the brain. The cerebrum is divided into two hemispheres by sulcus. It has many sulci and gyri. These two cerebral hemispheres are interconnected via a structure called corpus callosum.Each cerebral hemisphere is divided into four lobes; Frontal lobe, Parietal lobe, Temporal lobe, and the Occipital lobe. These lobes have different functions; they have areas that are concerned with specific functions. Frontal lobe performs functions like speech, movement, emotions and planning; parietal lobe is associated with some movements and perception; occipital lobe is responsible for all processes of vision, and temporal lobe is concerned with auditory, memory, and speech. It is thought that cerebrum is much older evolved than all the other parts of the brain.
What is Cerebellum?
The cerebellum is a center for hindbrain, it is smaller in size than cerebrum but is the second largest part of the brain and situated above the posterior cranial fossa of the skull. It is also called little brain of the body. Its has 10% of the volume of the brain but has 50% of neurons of all brain. It is further divided into these lobes; Central lobe or vermis, and Two lateral lobes or cerebellar hemisphere. The cerebellum has two main functions, one to maintain a proper posture of a body in every state and other is the maintenance of equilibrium while standing or walking, etc.
