Essay On Human Brain
The human brain is the most important organ in the nervous system. Located inside the head, surrounded by the skull. The human brain is very identical to the brains of other mammals, but with a more developed and evolved cerebral cortex. Much of the size of the human brain comes from the cerebral cortex, especially the frontal lobes, which are associated with executive functions such as self-control, planning, reasoning, and abstract thought. Before talking about the lobes. The most important part must be talked about and that is the human nervous system. The human nervous system has two major components and those are the central nervous system (CNS) and the peripheral nervous system (PNS) which consists of the brain and the spinal cord. These …show more content…
Neurons are the smallest building block in the brain. The average human body usually contain a hundred billion neurons and there a four types. First have sensory neurons that send messages to the central nervous system. Second the motor neurons work by sending messages from your brain to your central nervous system. Then there are your association neurons whose purpose is to carry message from one neuron to another. The human brain uses these neurons communicate the brain with the body. Equipped with four powerful lobes the human brain by far one of the most strong and evolved organs in our body. First the front of the brain known frontal lobe located behind your forehead. This part of brain controls human reasoning, planning, parts of speech and movement, emotions, and problem-solving. Next humans have their parietal lobe located on the side of their head behind the central sulcus. This controls your perception of stimuli such as touch, pressure, temperature and pain. Last just right below the lateral fissure you have the occipital lobe this is one your most important lobes because this controls your perception and recognition of auditory stimuli and memory. Any damage to any of this parts of the brains could result a significant change in who you are and as well as change your

    The command center of the human nervous system is the brain. The sensory organs send information to the brain, which then sends output to the muscles. The largest part of the brain is the cerebrum. Underneath the cerebrum lies the brainstem, and behind that sits the cerebellum. The outmost layer of the cerebrum is called the cerebral cortex, which has four lobes. There is a frontal lobe, parietal lobe, temporal lobe, and occipital lobe. The brain develops from three sections known as the forebrain, midbrain, and hindbrain. There are two hemispheres, the left and the right. These two hemispheres are connected by a bundle of nerve fibers called the corpus callosum.…

    The central nervous system is made up of two major components, the brain and the spinal cord. The spinal cord connects to the brain, and is the main messenger component to the rest of the body from the brain. There are several different parts of the brain including the hypothalamus, the thalamus, the corpus callosum, and the cerebellum ("The Central Nervous System", 2009). The hypothalamus is above the spinal cord, and regulates the consumption of food and water. It also “controls the release of sex hormones from the pituitary gland” (“The Central Nervous System”, 2009). The thalamus is responsible for passing on information from the senses to the brain. The corpus callosum connects the two hemispheres of the brain and helps with communication. The cerebellum stores procedural memory, and the cortex helps to make decisions and solve problems. The left hemisphere of the brain controls different aspects of the human body than the right hemisphere. The left hemisphere controls the right side of the body, and regulates speech, language, comprehension, analysis, calculations, time, sequencing, and recognition of words, letters and numbers…

    The cerebral cortex is “a large, deeply wrinkled sheet of neurons, or nerve cells, on the surface of the brain’s two hemispheres”. These are defined as the right and left hemispheres and make up the largest volume in the brain. The cerebral cortex controls all sensation, thought, comprehension, higher cognition, ideas, language, memory and emotion (Pinel, 2011). The hemispheres consist of four lobes, with each performing a specific function (Pinel, 2011).…

    The outer layer of our forebrain consists of the cerebral cortex. The cerebral cortex is so significant since it controls our ability to learn and store complex and abstract information. Also, it is our control and information processing center. The cerebral cortex consists of many interconnected neurons that are quite useful. The cerebral cortex covers the frontal lobe. This lobe is so important because it controls our organization, planning, and creative thinking. The frontal lobe is also in control of the planning of movements and working memory (events that happened very recently). The cerebral cortex and the frontal lobe help explain human behavior and overall human cognitive and physical functioning because they show the areas that…

    The human brain is made up of three parts which are the hindbrain, midbrain and the forebrain. The hindbrain controls our basic functions such as eating, breathing and sleeping. The midbrain integrates sensory information and gives information to the forebrain. It also regulates visual reflexes and co-ordinates the movements of the eye with those of the head and neck. The forebrain is the largest part of the brain and all higher levels of thinking are processed through this part. This is the part of the brain that differentiates us humans from other species. The cerebral cortex which is the outer layer of the forebrain gives us the ability to think and learn, store complex and abstract information, control of human senses, thoughts, language and memory, and it is the place that our conscious comes into play. The human brain is further divided into two hemispheres that make up the cerebrum. The left-hand side controls language and verbal skills, mathematical ability and analytical skills. The right-hand side controls non-verbal skills such as musical, spatial problems and processing information. This side also makes up our creativity and intuition as humans. It is human thinking and reasoning that makes us such a unique species especially with the cognitive process. When humans begin this process, they try to rearrange information in new forms that will allow…

    In the human body the brain is one of the main organs. It helps the body run and work properly. But, what happens if the brain stops working properly? It would affect the whole body. All the systems that the brain is in charge of would stop or not work well. If the brain stopped working properly the central nervous system, the limbic system, and the brain itself can be in danger.…

    Inside our brain, there is this system called the human nervous system. There are two types of nervous systems: the peripheral and central nervous systems. The peripheral nervous system includes the nerves connecting the central nervous system to the rest of the body. It has two subdivisions: somatic nervous system and autonomic nervous system. Somatic nervous system controls skeletal muscles and interacts with the external environment. An example is walking through a park. You are using your motor nerves, which relay messages from the central nervous system, to all the skeletal muscles of your body. The autonomic nervous system regulates the body’s internal environment, which consists of organs, glands, and blood vessels. An example is breathing.…

    Essay On Brain Plasticity

    • 3 Pages

    Although the brain was once seen as a rather static organ, it is now clear that the organization of brain circuitry is constantly changing as a function of experience. These changes are referred to as brain plasticity, and they are associated with functional changes that include phenomena such as memory, addiction, and recovery of function. Recent research has shown that brain plasticity and behavior can be influenced by a myriad of factors, including both pre- and postnatal experience, drugs, hormones, maturation, aging, diet, disease, and stress. Understanding how these factors influence brain organization and function is important not only for understanding both normal and abnormal behavior, but also for designing treatments for behavioral…

    If you think of the brain as a central computer that controls all the functions of your body, then the nervous system is like a network that relays messages back and forth from it to different parts of the body. It does this via the spinal cord, which runs from the brain down through the back and contains threadlike nerves that branch out to every organ and body part.…

    The nervous system is divided into two main areas, the peripheral nervous system and the central nervous system. The central nervous system controls the brain and spinal cord. The average human brain weighs approximately 3 pounds and contains approximately 100 billion neurons, as well as trillions of “support cells” called glia. The spinal cord weights approximately 35-40 grams and is around 43 cm long in adult woman and 45 cm long in adult men. The frontal lobe of the brain controls our judgement and is responsible for reasoning, planning and carrying out complex tasks. The frontal lobe works together with the amygdala. This is the part of the brain which is linked with emotional memory. The prefrontal cortex (part of the frontal lobe) analyses a situation, such as a student about to walk into an exam hall to take an important exam, and if the individual’s actual coping ability conflicts with the individual’s perceived coping ability i.e. the student panics and feels they are not fully prepared, then the amygdala will highlight that there is a problem. Depending on the actual problem, the prefrontal cortex can negotiate with the amygdala and try to defuse the situation. For example, the prefrontal cortex will try to reason with the amygdala and tell the amygdala to stop worrying and that they have prepared enough. However, in extreme circumstances, such as if the individual begins to doubt their self esteem, the amygdala can neuro hijack the prefrontal cortex resulting in extreme stress such as rage. The amygdala then signals the hypothalamus releasing the neurotransmitter chemical noradrenaline which activates the sympathetic branch of the autonomic nervous system, part of the peripheral nervous system.…
