The cortex is a layer sometimes mentioned as the grey matter. The cortex covers about 1.5mm to 5mm of the outer most portions of both the cerebrum and cerebellum. The cerebral cortex comes from the section that covers the cerebrum. The cerebral cortex equates to about two thirds the mass of the brain it is cover with folded bulges called gyri that make deep valleys called sulci. This increases the surface area of the cortex and allows more and faster neuron processing. This part of the brain is split into two hemispheres and is consider the most complex and developed part of them brain being the most recently evolved section of the brain. The cerebral cortex is where the majority of the information processing occurs; the different lobes and cognitive functions control all of this processing. These lobes are the parietal lobe, frontal lobe, occipital lobe, and temporal lobes. The information that these lobes process in the brain allow us as humans to think, see, feel, speak, and much more one can say the cerebral cortex makes being human possible. However many
One of the most important lobes is the Parietal lobe this lobe controls cognition information processing pain and touch sensation, spatial orientation, speech, and visual perception. This lobe is located near the center of the brain behind the frontal lobe; it is located under the parietal bone and is split into left and right hemispheres. The primary sensory area is where the sensations from the skin such as touch, hot cold, and pain. The more sensory input an individual receives the more surface area of the cerebral cortex is used to analyze that input. Spatial information is the ability of the parietal lobe is lets us judge distance and shapes; without this we would not ...

The cerebral cortex is a multi hemisphere, and the largest part of the brain. The cerebral cortex is responsible for cognitive, auditory, visual, memory, and motor function; being the most recent addition of the evolved brain its believe that the cerebral cortex makes us an intelligent race. It is thanks to the cerebral cortex that we have our most important and complex creations. Yet is also responsible for our ability to do the simplest task such as driving or walking; it gives us the ability to see what is in front of us to hear what is around us, and understand what we mean. Without it we would not be able to feel any emotion love, or anger. The cerebral cortex is truly one the most important organs that the human body has.

A Study Of Nervous Systems, Anatomy And Physiology Essay

- Question 6-The approach that fascinates me the most is neuroscience; furthermore, neuroscience is the study of nervous systems, anatomy and physiology. Neuroscience is preoccupied with both the organization of the system in humans, animals and their purposes. Neuroscience proposes a body of information that serves as an infrastructure for comprehending how cognitive operations are conveyed. Cognitive neuroscience focuses on cognitive processes, which are visual, object recognition, attention, memory, problem solving and language (Friedenberg and Silverman, 2012)....   [tags: Human brain, Brain, Nervous system]

The Human Brain Essay

- The human body is crammed with a wide variety of secrecy. There are so many parts that make up the human body that sometimes one just cannot remember them all, or they have never heard of them. An example of one part of the human body lies inside of the nervous system, your brain. Your brain is divided into three main parts which are the forebrain, midbrain, and hindbrain. The brain has multiple functions in addition to it being pretty remarkable. According to Brain Anatomy, the average human brain weighs about three pounds or 1,300-1,400 grams....   [tags: Anatomy]

The Most Important Organ Of Our Body Essay

- The heart is the most important organ in our body. Some people think this is true, but there not a hundred percent wrong because we do need the heart to live. On the contrary the part most important to the human body is the brain, to our body besides other important parts like the heart, lungs, and other organs. It’s used for more than one role like the other type of organs. On the contrary the brain helps with hearing, seeing, learning, feeling, and etc. We would be lost without the brain and dead of course, without all the effort the brain does the human body wouldn’t be completed....   [tags: Cerebrum, Cerebral cortex, Frontal lobe]

Some Fact About The Prolific Theories of Bone Growth Anatomy Essay

- ... Therefore by alternating a madder-treated with a normal diet, he observed a series alternating red with white layers of bone, each corresponding to a change in the animal’s diet thereby proving that bone grew by interstitial formation; increasing in thickness by adding layers that grow out of the periosteum. Duhamel also found that bone “turned over”. The red colour left the bones a month after he stopped feeding madder to the animals. Madder is taken up in bone laid down at sites of fracture repair and appears to interfere with development of a fracture callus....   [tags: healing of bones fracture, femur]

Essay about Anatomy of the Brain and Its Functions

- The brain is the perception responder and critical thought processor. Along with the brain’s control of all physical action and coordination, it has all control over emotional response and impulse. The brain’s dictation of all normality and actions made are only a small concentration of what the brain is truly capable of and scientists are working towards expanding this theory. This has been such a controversial issue, compiled with the hopeful idea of a cure for brain disease, a daunting possibility that could potentially “blur the lines between man and machine” (Kate Kelland, 2012.) It has been a well-known fact that humans only use a small percentage of our actual brain capability....   [tags: cerebellum, frontal lobe, occipital lobe]

Anatomy: How the Muscles Work Essay

- In order for a skeletal muscle to contract, a signal must be first sent from the primary motor cortex which is located in the precentral gyrus of the cerebral cortex. This is considered to be an Upper motor neuron. These fibers travel through the brain via the internal capsule until they get to the lower portion of the medulla oblongata. At this point, the neuron crosses over to the other side of the body. This means that if a neuron is to inervate the right bicep muscle, it originated in the left side of the precentral gyrus and crossed over to the right side at the medulla oblongata....   [tags: signals, neurons, membrane]
