Function of cerebrum class 10

Overview What is the brain? Your brain is an essential organ. All of your emotions, sensations, aspirations and everything that makes you uniquely individual come from your brain. This complex organ has many functions. It receives, processes and interprets information. Your brain also stores memories and controls your movements. Your brain is one component of your central Function What is the brain’s function? Your brain receives information from your five senses: sight, smell, sound, touch and taste. Your brain also receives inputs including touch, vibration, pain and temperature from the rest of your body as well as autonomic (involuntary) inputs from your organs. It interprets this information so you can understand and associate meaning with what goes on around you. Your brain enables: • Thoughts and decisions. • Memories and emotions. • Movements (motor function), balance and coordination. • Perception of various sensations including pain. • Automatic behavior such as breathing, heart rate, sleep and temperature control. • Regulation of organ function. • Speech and language functions. • Fight or flight response ( Anatomy What are the main parts of the brain? Your brain’s structure is complex. It has three main sections: • Cerebrum : Your cerebrum interprets sights, sounds and touches. It also regulates emotions, reasoning and learning. Your cerebrum makes up about 80% of your brain. • Cerebellum : Your cerebellum maintains your balance, posture, coordination and fine m...

Between the tip of each of the axon’s terminal fibres and the dendrites of another neuron– the junction point known as synapse – is a tiny synaptic gap or cleft. The message of one neuron crosses to another neuron by means of a complicated event. An electricalimpulse travelling down the axon releases into this gap molecules of the neurotransmitter. These molecules cross the gap and excite activity in the second neuron. The neuron then fires an electrical impulse along its own axon. The strength of the impulse depends upon the total impact it receives from the incoming messages at the synapses. Meanwhile at each synapse, the neurotransmitter chemicals are either absorbed by other neurons or chemically destroyed. Q.5.

Cerebrum: Anatomy, Function and Location Table of Contents • • • • • • • • • Cerebrum Meaning and Location Our brain consists of three main parts: cerebrum, cerebellum and brainstem. The cerebrum is the largest part of the brain. It is situated in the uppermost part of the brain. It is divided into left and right hemispheres by deep fissures but they remain in contact with each other by the corpus callosum. The cerebrum consists of the cerebral cortex (of both the hemispheres) and other subcortical structures such as the hippocampus, basal ganglia and olfactory bulb. The cerebrum is also known as the endbrain or telencephalon. The cerebrum assists in controlling language, somatosensory, cognitive, motor, emotions and memory related functions. Cerebrum Anatomy Cerebrum is the largest and most developed portion of the human brain. It is located in the uppermost part of the brain. However, in some animals it lies on top or in front of the brainstem. The cerebrum is divided into two hemispheres, it is made up of cerebral cortices which is the outer layer of grey matter and the hidden regions of white matter. The two hemispheres are C-shaped and are separated from each other by deep longitudinal fissures. Other subcortical structures of the cerebrum include basal ganglia, olfactory bulb and hippocampus. Refer: Cerebral Hemisphere The two cerebral hemispheres have an outer layer of cerebral cortex that is made up of grey matter. The core or the inner layer of the cerebrum is mad...

The Parts of the human brain The human brain is made up different parts and compartments, for each of the functions. Take a look at the different parts of the brain. • Forebrain • Midbrain • Hind Brain (Source – Wikipedia) Fore Brain It is the main thinking part of the brain and controls the voluntary actions. The forebrain processes sensory information that is collected from the various The forebrain consists of the Cerebrum, Thalamus and Hypothalamus. The cerebrum is the biggest part of the brain. This part we associate with higher brain functions such as thinking and action. It contains the cerebral cortex and other subcortical structures. The cerebral cortex is highly wrinkled and makes the brain very efficient. Now the cerebral cortex again divides into four divisions called lobes. They are: • Frontal lobe –Is associated with parts of speech, • Parietal lobe – We associate parietal lobe with recognition, orientation, and perception of stimuli • Occipital lobe – Is responsible for visual processing • Temporal lobe – Finally temporal lobe is associated with memory, speech perception and recognition of auditory stimuli The cerebrum is divided into two halves by a deep furrow. These halves are the left and right hemispheres. Each side functions slightly different from the other, even though they are symmetrical. So the right hemisphere links to creativity whereas the left hemisphere relates to logic abilities. And Corpus callosum connects the two hemispheres. Mid Brain Th...

The cerebrum and cerebellum are two of the four main regions of the brain. People often confuse them because of their sound-alike names and similar symmetrical structure. Although both play equally important roles in the brain, there are major differences between these two brain regions. In this article, we’ll conduct a quick cerebrum vs cerebellum comparison. To explain how these two parts of the brain are different from each other, we will compare their size, their position in the brain, as well as their main functions. What Is the Difference Between the Cerebrum vs. Cerebellum? The most obvious difference between the cerebrum and cerebellum is their size. Accounting for approximately 85% of the brain’s total weight, the cerebrum is the largest region of the brain. The cerebellum, on the other hand, is much smaller. It makes up 10% of the total brain volume. This doesn’t make the cerebellum any less important, though, seeing as it houses more than half of all neurons in the brain. One of the distinctions between the cerebrum and cerebellum is that they’re positioned in different places. The cerebrum takes up the entire upper portion of the brain, whereas the cerebellum is located right underneath it, in the lower rear portion of the brain. The two are separated by dura mater. Rather than having a direct connection, the cerebellum communicates with the cerebrum via the brain stem. What Is the Function of the Cerebrum and Cerebellum? The key difference between the cerebrum...

The Cerebrum is the main part of the brain in humans and other vertebrates. Functionally, it obtains information from your surroundings and/or body and then sends that information to a specific part of the cerebrum. The cerebrum interprets the knowledge and decides what must happen next. In short, your cerebrum, although approximately the size of a cantaloupe, holds the instructions for everything you do in your daily life. There are two temporal lobes, one in each hemisphere - close to where your ears are. It primarily functions in auditory processing. However, it may also be involved in emotion, learning, and pronunciation/learning a new language. If you hear a loud tempo or beat, you may cover your ears, thus blocking the sounds from getting to your temporal lobe. The frontal lobe allows you to solve a complex task, undergo a voluntary movement of your body parts, form complete sentences, and is responsible for your personality traits. Think about the last time you had a difficult exam, what was your first reaction? You probably put your elbow on the table and your hand on your forehead, precisely where your frontal lobe is located. The parietal lobe functions in general sensation and feeling. If you stand too close to a campfire, you probably take a few steps backward to avoid the excessive heat. Building a snowman without gloves may also bring you discomfort, but your parietal lobe helps to communicate this information with the rest of your brain. Although all sensati...

Your brain consists of four main regions: the cerebrum, cerebellum, brain stem, and diencephalon. Each region of the brain performs certain functions and plays a role in the body. They all work together to ensure that your brain and body are performing the way they should. In this article, we will take a closer look at all four parts of the brain and explain their roles. We will start with the largest brain region and examine the main cerebrum function. What Is the Role of the Cerebrum? The cerebrum is the anterior part of the brain. As large as a cantaloupe, this region accounts for about 85% of the total brain weight. So, what does the cerebrum do? This region is responsible for high brain functions like thinking, learning, and memory. The cerebrum is also in charge of organizing, planning, and language processing. In addition, this part of the brain is also tasked with interpreting and processing the information obtained from the five senses. The outside of the cerebrum is covered with a thin layer of gray matter called the cerebral cortex. This part of the cerebrum is in charge of your motor skills and helps the brain control voluntary movements. Furthermore, the cortex also has association areas that allow you to perceive ideas and objects in a meaningful way. It also has centers that help you control your impulses and manage your anger. To ensure that your cerebrum is working to its full potential, you need to give your brain a good mental workout every day. The best...
