The Power of the Human Brain Essays

“The Human Brain”, by myPerspectives, is an informative article that claims that the brain is a complex organ that is truly impressive. The brain is a key part of the central nervous system, that controls the entire body’s activities, to simple things such as breathing. These actions are fired through neurons, that quickly travel through the spinal cord. Surprisingly, the brain transmits these messages at an unimaginable rate, at 150 miles per hour, through 85 billion cells, called neurons. These neurons can form up to 10,000 synapses, or connections to each other. By itself, the brain can create billions of synapses, which change the structure of the brain every time new information is learned. However, there is still much that scientists

I started my education in Erie, Pennslyviana.I attend McDowell High. I would say that we were one of the richer schools were I live. I am going to talk about my first assignment Brainology. I thought it was very interesting and it thought me a lot about how some people have different mindsets.

The nervous system is made up of basic units called neurons. The main role of the neurons is to receive, integrate and transmit information throughout the body. There are some neuroglial cells found in nervous system aswell which provide support to the neurons by giving protection and nourishment Neurons have nerve processes that looks like finger like projections extended from the nerve cell body. They also contain axons and dendrites which enable them to transmit signals throughout the body. Normally, axon carry signals away from the cell body and dendrites carry signals toward the cell body according to Regina Bailey (2013). Neurons have three different shapes: bipolar, unipolar and multipolar where bipolar has two neuronal processes coming out of the cell body, unipolar has only one neuronal process coming out of the cell body and multipolar has many neuronal processes coming out of the cell body.

The brain stem or the medulla is the closest to the spinal cord. The brainstem is responsible for most of the human bodily functions. The brain stem is critical for human survival and normal human functions. The brain stem is also responsible for information of pain and touch from the head and neck; it is also responsible for the inputs from the face and the mouth. Reticular formation is a group of neurons, nuclei, that are important for sleep and wakefulness. In reticular formation there is nuclei that are a major source of neurotransmitter serotonin. Serotonin is important for regulating mood and activities.

The six primary structures of the brain are the Brain Stem, the Cerebellum, the Occipital Lobe, the Temporal Lobe, the Parietal Lobe, and the Frontal Lobe. The Brain Stem is underneath the limbic system. It is responsible for the basic functions such as breathing, heartbeat, and blood pressure. The Cerebellum is behind the spinal cord. Its function is coordination for movement, posture, and balance. The Occipital Lobe is at the backside of the brain. Its function is processing visual information, such as color, shape and motion. The Temporal Lobe is over the ears and its function involves hearing, language processing and memory. The Parietal Lobe is at the

The cerebral cortex is the cerebrum’s outer layer. It is divided into four lobes, the frontal lobe, parietal lobe, temporal lobe, and occipital lobe.

The part of the brain that I picked is the Cerebellum. The Cerebellum is the part of the brain at the back of the skull in the vertebrates. Its function is to coordinate and regulate muscular activity. The Cerebellum is located behind the top part of the brain stem, it is where the spinal cord meets the brain, the Cerebellum is made of two hemispheres. The Cerebellum receives information from the sensory systems, the spinal cord, and other different parts of the brain, and then it also regulates motor movements. The Cerebellum coordinates voluntary movements such as posture, balance, coordination, and speech, and then it results in smooth and balanced muscular activity.

Within the subcortical structures, underneath the cortex, are the thalamus, amygdala, caudate, putamen, hippocampus, and cerebellum. These structures provide all sensory and motor responses, emotional and social responses, and support memory recognition.

The cerebrum is situated at the back of the brain. The cerebrum is divided into two cerebral hemispheres, left and right. It consists of the corpus, callosm, and nerve fibers. The left and right hemispheres communicate with each other. The brain stem “connects the brain to the spinal cord” (Lu & Bludua, 2011), which regulates the body. The cerebellum is positioned beneath the cerebrum. It manages a person’s equilibrium and coordination.

Basal ganglia and cerebellar loops: motor and cognitive circuits: The basal ganglia and cerebellum are the major motor structures of the brain. In this study, several cortical areas were examined as the targets of the signals sent by the basal ganglia and the cerebellar output. This article examined

The cerebellum’s function is to manage muscular activity. The cerebellum contains many cells and it can be separated into three sections. Each of the cerebellum’s regions executes different parts of the cerebellum’s functions. The first region is the vestibulocerebellum and it helps the body maintains its balance and controls its visual movement. The second area of the cerebellum is the spinocerebellum and it manages the activity of the limb and body. The third section of the cerebellum is neocerebellum and it coordinates body movement and assesses information from the cerebral cortex and dentate

The Brain and the Spinal Cord are both components of the nervous system. The nervous system is what carries messages from the brain to the spinal cord and then sends these messages to various locations within the body. The nervous system is comprised of two systems, the first being the Central nervous system. The Central Nervous system is comprised of two main components which are the brain and the spinal cord. The second being the Peripheral Nervous System which is comprised of the autonomic and somatic nervous systems. The Brain is divided into four main parts, the brain stem, the cerebellum, the cerebrum and the diencephalon. Within the brain there are two types of matter the Brain Grey matter, which is responsible for receiving and storing impulses (cell neurons are located in the grey matter), and White Brain Matter, which carries the impulses sent by the Grey Brain Matter. The brain stem is what connects the brain to the spinal cord and is otherwise known as the medulla oblongata. There are other components that comprise the nervous system such as meninges (Three layers of membrane that cover the brain and spinal cord, they act as protection to the brain and spinal cord against bacteria and microorganisms) and neurons which are comprised of

In general, the cerebellum is responsible for controlling motor functions and muscle coordination. It has the ability to control how people move, walk, talk, and other physical activities, which means that it will control the aspects of balance and muscle tone, those are the important factors that provide for smooth movement and activity. If cerebellum is damaged, it causes parts of the body to shake uncontrollably. People with damaged cerebellum may experience the loss of coordination of motor movement; the inability to judge distance and when to stop; the inability to perform fast alternating movements and so

The cortex consists of four sections, called "lobes". The frontal lobe is connected to reasoning, planning, speech, movement, emotions, and problem solving. The parietal lobe is associated with balance, recognizing, and movement. The occipital lobe is associated with vision. The temporal lobe is connected to hearing, memory, and speech. The cortex is highly wrinkled, making the brain more convenient, as this increases the brain's surface area, giving it more room for neurons. The cerebrum is divided into two hemispheres- the left hemisphere, and the right hemisphere. The right hemisphere is associated with creativity, and the left one is linked with logic. A bundle of nerve fibers, known as the corpus callosum connects these "hemispheres" (Brain Structures and their Functions). The cerebellum, which is also known as the "little brain", is similar to the cerebrum, since it also has two hemispheres and a highly folded surface. This part of the brain is linked with movement and balance. The cerebellum is assumed to be older than the cerebrum "evolutionarily" (Brain Structures and Their Functions). The brain stem controls basic life functions such as blood pressure, breathing, and heartbeat. Scientists say that the brain stem is the simplest part of the brain (Brain Structures and Their Functions).
