Like the cerebrum, it also contains grey as well as white matter. Anterior, posterior and flocculonodular lobe are the three lobes found in the cerebellum. Zones : A cerebellum has three zones, namely vermis, intermediate and lateral hemisphere. Both cerebrum and cerebellum are the two structures of the central nervous system.
The cerebrum controls the thinking related processes like reasoning, learning, planning, judging , emotions or impulse control, visual memory, verbal memory, and interprets the sensory information.
Cerebellum monitors the coordination in muscle movement. Therefore, cerebrum and cerebellum are the two different structures that complement each other in a way and coordinate to help us perform tasks and memorize things.

It is located near the middle part. Temporal Lobe - It is responsible for short-term memory, speech, and musical rhythm and sits at the sides of each hemisphere. Occipital Lobe - It is primarily associated with processing vision and is located at the back of the brain.
The cerebrum also contains certain types of neurons. Sensory neurons are responsible for sensation. Motor neurons control voluntary and involuntary movements.
Interneurons are nerves that connect with neurons. Cerebellum, which is also called the little brain, is located just below the cerebrum. It is a part of our hindbrain. It is primarily responsible for coordinating voluntary movements. It is also responsible for certain motor functions such as balance, coordination, and posture. The cerebellum consists of a ventricle filled with fluid and a cortex covering the white matter.
It is also further divided into two hemispheres. The main components of the cerebellum are:. It is divided into two hemispheres, viz right and left hemispheres. Each of these hemispheres controls the body on the opposite side. The foresaid hemispherical division of the cerebrum is made up with the help of the median longitudinal fissure. Each hemisphere is composed of 4 lobes namely, Frontal, parietal, temporal and occipital. Each of these lobes is primarily associated with an individual group of functions.
And also each side of the hemisphere is related to a particular set of abilities. For instance, the person who has more right-brain activities will be more efficient in creativity, spatial skills, music, and other artistic skills. Whereas, the person with left-brain dominance, will be more efficient with logical reasoning, arithmetic operations, writing. The cerebrum is divided based on the nature of the cells it is made of into, grey matter and white matter.
The grey matter represents the cell bodies of a variety of neurons while the white matter represents the extensions of the cell bodies, which we call axons. The cerebral hemisphere on external appearance reveals elevations and depressions on the surfaces which are called gyri and sulci respectively. Central, lateral and lunate sulci are those which form the boundaries between the lobes of the cerebral hemispheres.
Superior temporal, precentral and postcentral gyri are those which separates the cortex based on functional significance. Very nice but one things is wrong In cerebrum it is not in fifths of wieght he is fourth of weight. Facebook Twitter. The cerebrum consists of two cerebral hemisphere joined by a curved thick band of nerve fibres, called corpus callosum.
The outer layer of the cerebrum , known as cerebral cortex , is formed of grey matter and white matter. The cerebellum is similar to cerebrum in that it has two hemispheres and has a highly folded surface or cortex.
The cerebellum is the second largest part of the brain, and is located at the back of the skull. Tags Cerebrum and Cerebellum Cerebrum vs Cerebellum.
