Fig1.5. shows a broad overview of the cerebral cortex.
Firstly, there is various of sensing activities as in seeing and hearing as in a sense of understanding of what is seen and heard. Secondly the sense of feeling in numerous parts of the body from the head to the toes. The ability to recall past events, the sophisticated emotions and the thinking process. The cerebellum acts as a physiological microcomputer which intercepts various sensory and motor nerves to smooth out what would otherwise be jerky muscle motions. The medulla controls the elementary functions responsible for life, such as breathing, cardiac rate and kidney functions. The medulla contains numerous of timing mechanisms as well as other interconnections that control swallowing and salivations.
The cerebrum consists of two hemispheres, separated by a deep fissure called the Corpus Callosum, the hemispheres are divided into four lobes; the frontal, partials, occipital and temporal.
The Frontal Lobe: Is the anterior part of cerebral hemisphere of the cerebrum of the brain, extending back to region called the central sulcus is a deep cleft on the upper surface of the brain. The frontal lobe is for intelligence which carries out high mental procedures such as thinking, judgment making, and forecasting. The human body uses their frontal lobe nearly every day. The frontal lobe

Here the sensory data is stored and consists mainly of the senses found within the body which comprises of taste, touch, smell, temperature. Here these senses are integrated and processed before being transported to the necessary region to fulfil the response. If the parietal lobe was severed or damaged the human body would not be able to function properly as in the human body would not be to feel nor touch nor sense the feeling of being touch due the damaged that controls this motion in the parietal
The two hemispheres of the brain are the left and the right hemisphere. Each having it's own unique purpose and function. The two hemispheres are separated by a fold down the middle connected only by a thick nerve cable called the corpus callosum. The Left hemisphere is thought to be the logical side controlling speech, reading, writing, details, facts, maths and science and rational, literal, practical analysis. The right hemisphere is seen as controlling the intuitive, creative side of life, with spatial perception, symbols and images, face recognition, imagination, beliefs and fantasy.

Based on the findings presented, Dr. Green made the correct diagnosis in predicting that this gentleman had a spinal cord injury.
The frontal lobe comprises a third of the brain and it enables us to engage in higher cognitive functions such as planning and problem solving (Jonides & Smith, 1999). The frontal lobe is divided into 3 regions, the motor cortex, premotor cortex, and prefrontal cortex. The motor cortex is located in the precentral gyrus and directs fine motor coordination. The premotor cortex is involved in planning, organizing, and integrating body movements. The prefrontal is involved in executive functions, including short-term memory, working memory, decision making, and prioritizing behaviors (Wilson, 2003). Some of the frontal lobe disorders than can cause brain damage and behavioral changes are Huntington’s disease, infection, stroke, tourettes, dementia, epilepsy, Parkinson’s disease, tumors, closed head injury and traumatic brain injury (Chow, 2000).
The left and right hemispheres of the brain are each divided into sections. Within each sections are lobes, controlling such processes as our visualization, our movement, and our personalities. For instance, the occipital lobe in the back of our brain is responsible for processing vision, and the frontal lobe behind our forehead controls cognition and personality. The lobes of the brain are split between the right and left hemispheres of the brain. This well-designed arrangement is for the lobes to function correctly, so the two hemispheres of the brain can communicate with one
The brain has many different parts to it which help one function through daily life; parts such as the cerebrum which controls voluntary movement and regulates functions such as thinking, speaking and the ability to recall information. The cerebellum controls the balance and coordination and finally the brain stem, which consists of the medulla oblongata and the spinal cord which controls all involuntary functions such as breathing, heart rate and blood pressure. The brain stem is also able to carry out these actions even when someone is asleep. To fully understand how crucial the brain is to survival one must understand the functions of the brain stem.
Look only at Gage’s case study for this essay, the frontal lobe and its position in the brain will be the area of focus in this essay. According to Weiten in the tenth edition of Psychology: Themes and Variation, when describing the frontal lobe region, he expounds in great

The nervous system and the important sensory organs play a key role in the day-to-day
The brain is one of the most interesting yet the most complex part of the body. Since no one can really see what’s inside, it’s a big question for most people on how it works. The brain is made up of more than 100 billion neurons that communicate through the synapse. It controls all the function of the body, receive and interprets information and process thoughts and emotions (Hines, 2016). It is one of the most important part of the body. How we remember, how we think, do and etc. is made possible because of the brain. The brain is divided into three main parts: cerebellum, cerebrum and brainstem. Each part has its own specialised area on the body in order to function well (Hines, 2016).
In many opinions it is thought that the brain and the neurons have less than importance than the heart. However, there is large quantities that people disagree that the brain and neurons are an important factor in our body. One study showed, the brain is the one that control every part of the body. Awhile the neurons travels across a synapse se...
The central nervous system is consisting of the brain, spinal cord and then there is the peripheral nervous system, which of course is separated into two systems, somatic nervous system is broken into the afferent and efferent nerves and autonomic nervous system. The somatic nervous system is broken down into the afferent and efferent nerves. Afferent is signals traveling towards the spinal cord, and efferent signals travel towards the brain. Then of course, the autonomic nervous system has afferent and efferent nerves since of course information must be relayed between the spin and the brain. The efferent nerves can then can be further separated into two more systems called the sympathetic nervous system and the parasympathetic nervous system.
The area at the front of the brain is the largest. Most of it is known as the cerebrum. It controls all of the movements that you have to think about, thought and memory.
Since the brain and the nervous systems are in need of each other to perform their functions it is important to look at the brain and all of it 's features. The brain is the control center that process the majority of all the bodies functions. The spinal cord is responsible for certain simple muscle reflexes but the brain process both conscious and unconscious.
The nervous system’s main function is to coordinate all of the activities in the body. The main organs are the cerebellum, which controls and coordinates movement. The cerebrum, is the center for conscious thought, learning, and memory. The last main organ is the brain stem. The brain stem keeps the automatic systems in your body working. Problems of the nervous system include, epilepsy, Alzheimer’s, and multiple sclerosis. You can care for your nervous system by wearing a seatbelt, wearing a helmet, and by not using drugs or alcohol. Something very confusing about the nervous system is that the left side of human brain controls the right side of the body and the right side of the brain controls the left side of the body!
This arc belongs to the autonomic nervous system (ANS). The ANS is the part of the peripheral nervous system that is responsible for controlling involuntary body functions. This system helps us maintain a steady heartbeat while we are sleeping, and anything else that is necessary to keep us alive during low levels of consciousness. This system affects the body functions that are not consciously managed, such as breathing, digestion, heart rate, pupillary dilation, and urination. However, there are some ANS actions that we are able to control with our mind to a certain extent, such as swallowing.
