The Central Nervous System from Superficial to Deep Essay Example for Free

The Central Nervous System from Superficial to Deep Essay Purpose: The purpose of this lab is to understand the way that nervous system structures are arranged inside of the brain from the most superior, which would be the cortex or telencephalon to the most inferior, which would be the medulla oblongata. We are observing all the structures in the brain, as well as the protective tissue that surrounds it. Procedure: I had to use Primal Pictures, as it was necessary to complete this lab. Once logged in, there is a list of choices to click on as to where you want to go. On the homepage, click on the 3D Head and Neck and then go to the Brain folder. Next click on Meninges to access the pictures. Begin at layer 9. To identify the structures, just click on them. With Primal Pictures, there are different controls on the page that allow us to be able to view the brain, or any structure that we are looking at from different angles and different layers. There is also a summary of the structure that is being looked at. Using the guide that Dr. Poll has provided and Primal Pictures, we are to go through the different structures and gather all the information necessary to complete this lab. Results: Following the guidelines on our instruction sheet, we were to begin at Layer 9 of the brain, which showed us the meninges. From here, we could see the structures that protect the brain. Brain protection begins with the skull; it is the outermost layer. The three layers of meningeal linings are inferior to the skull. These include the dura mater, which is the outermost layer. It is also the toughest layer and in English is translated to â€Å"hard mother.† The dura mater has two layers. Inferior to the dura mater is the arachnoid mater. The most inferior layer of the meninges is the pia mater. It is also the deepest and softest layer. Next we looked at the sinuses that are part of the nervous system in Layer 5. A sinus is a cavity within a bone or other tissue. They are channels, or pathways that connect together allowing drainage of the veins that are in the brain. In other words, they function to help the collection and return flow of venous blood and  cerebrospinal fluid d rainage from the tissues and veins in the cerebrum. In Layer 4, we can see the falx cerebri. It is an infolding of the dura mater and separates the cerebral hemispheres. Now moving to Layer 10 in the brain folder, we can observe the cerebral cortex and all the structures inferior to it. The outer surface of the cerebrum is the cerebral cortex. It is composed of gray matter and just inferior to it is the white mater. We also can see the corpus callosum, which is a large bundle of axons that connect the right cerebral hemisphere to the left cerebral hemisphere. These axons carry information, in the form of nerve impulses, from one hemisphere to the other. The lateral ventricles are superior to the diencephalon, but are inferior to the corpus callosum. In Layer 3, we can see the basal ganglia. The basal ganglia form a set of interconnected nuclei in the forebrain. They receive a large amount of input from cerebral cortex and after processing it, send it back to the cerebral cortex via thalamus. The different components of the basal ganglia are the caudate nucleus, the putamen and the globus pallidus. The caudate nucleus is the most superior part. It is superior and lateral when compared to the thalamus. The most lateral part of the basal ganglia is the putamen and the most medial part is the globus pallidus. The limbic system is a complex set of brain structures that lie on both sides of the thalamus. It includes structures from the telencephalon, diencephalon, and mesencephalon. It includes the olfactory bulbs, hippocampus, and amygdala to name a few. This system supports many functions that include emotion, behavior, motivation, long-term memory, and olfaction. It is responsible for emotional life and has do with the formation of memories. The limbic system surrounds that structures that make up the diencephalon and is posterior to the temporal lobe. From the cerebrum view in Layer 5, we can locate the insula, or hidden lobe. It is posterior to the lateral sulcus. In other words, it is hidden beneath the lateral sulcus. In Layer 3, we can see the sulci and gyri. The longitudinal fissure is what separates the left and right hemispheres. The central sulcus separates the parietal lobe from the frontal lobe. It lies in between the precentral gyri (forms the motor strip) and postcentral (forms the primary sensory cortex) gyri. The lateral sulcus, also called the Sylvian fissure, is the most lateral boundary. It separates both the frontal lobe and parietal lobe, which are above, from the temporal lobe, which is below. Conclusion: In conclusion, we â€Å"dissected† the brain from the most superficial layer to the deepest layer and from the most superior layer to the most inferior layer. We were able to do so by using Primal Pictures. Being able to look at each structure from every angle and different layers is very beneficial when first learning about them. This site gives very detailed representations of the structures and explanations of how each structure works, not only on its own, but as a whole. All the structures in the central nervous system that we observed are in some way related and allow for communication to take place, as well as allowing the central nervous system to function as it is supposed to.

The Western as Commentary about Decaying Values Essay -- Western Cultu

The Western as Commentary about Decaying Values The Western, as a genre, is subversive of the values that its Christian characters possess. Western films frequently depict social depravity in terms of the mythology that developed during westward expansion. The mythology was inspired by the threat of the frontier wilderness to Puritan culture. In order to preserve their society, some Puritans departed from their ideal Christian lives. Western films portray compromises that cultures make of the values that they define themselves by in order to protect the integrity of their other values. A contemporary Western, Open Range, which Kevin Costner stars in and directed, released in 1995, deals with a conflict between morality and justice and the genre mythology. In it, Boss Spearman and Charley Waite herd cattle across the Western frontier. When they allow the herd to free-graze in Fort Harmon country, they infuriate a prominent rancher, Baxter, who tells them â€Å"Free-grazers ain’t gonna take the feed off my cattle.† A confrontation with Baxter’s henchmen results in them killing one of Boss’ helpers and another, Button, is severely hurt. Boss and Charley are faced with the options either to run away, in which case Button would die, or to risk their lives by entering the town to find him a doctor. Boss and Charley both are generous to each other, their workers, and people they encounter. Charley is a former Civil War fighter who is trying to escape his past with the guidance of the old, collected cowboy, Boss. Both have clearly been in fights before; however, Charley’s past troubles him in a deeper way than his demeanor suggests. He explains that he first shot a man in the throat ... ...fe from the dangers of their enemies and feel that they have the freedom of pioneers. Even as the wilderness and the frontier become more distant, the mythology that arose in the American west keeps its people inexorably determined to maintain the democracy and the freedom that it provides.

Bio-Medical Discourse

Discuss the strengths and limitations of social work practice within an organization, such as a hospital, that operates from a biomedical discourse (give an example)? The biomedical discourse is one of the most influential discourses in the health care profession today (Healy, p. 20). Biomedicine is a dominant and pervasive model in health care settings and there are strengths and limitations in working within the this discourse.One of the strengths of working within this model, it allows you to work within a multidisciplinary team with psychiatrists, doctors, nurses, and other medical staff and this opens up a whole new perspective for social workers. We get to see the medical side of things and how that affects the person. When a medical professional see’s a patient they see the direct problem of that patient and there disease.Using this model and all of our social work skills and approaches will give us a total picture of what is happening in that person’s life by no t only looking at the environment but putting other factors into place such as the biological aspect. We can help out clients navigate through the health care system and can clarify medical terms to help them feel at ease with there illness. The biomedical discourse has its limitations as well.This model works under the belief that disease’s are caused by a specific biological agents or processes and fails to take a deeper look at the individual environment and living factors. It is out job as social workers to look at all of the other factors such as environment, family, culture ect of that individual, not just the focusing on the person and modifying the person. I worked with a social worker on the cardiac rehab unit at the Glenrose Hospital and she worked with a patient that had a heart attack and had bypass surgery and is now in rehab.He was given medications to take after the surgery and most likely will be on for the rest of his life. The doctors tell the patient all ab out the medial procedure they just had, what current medications they are on and how to take them and what the side effects are, nut never talk about all the other factors that come into play. The social worker has to now prepare not only the patient to return home but has to prepare the family as to how there environment will be changing in order to have a safe recovery for the patient.As social workers it can be hard for us to ignore the environmental contributions in an individual’s life. The social worker only had two visits with the patient and the family, the nutritionist had another two visit’s and the physician has on going visits with the patient for as long is needed. The physician was only concerned with the disease and diagnosis of the patient and modifying the person. Another limitation is the focus on medicalization. Not everyone is in need of medical attention and to be put on medication.Our jobs as social workers are to recognize that people’s en vironments really do affect them. Person can come into see there GP and tell them that they are depressed, the first thing they do is put them on med’s for their depression. They don’t look at what has been going on in that person’s life, have they been through a major trauma, what changes have been happening. All they look at are the symptoms and the medications to go along side of them. This determines that the doctor is the expert and knows best.

Erik Erikson And Jean Piaget s Theories Essay - 1291 Words

Erik Erikson and Jean Piaget are quite similar in their theories. Jean Piaget’s cognitive theory is only slightly different than Erik Erikson’s psychosocial theory. Both theorists use the idea of developmental stages. Although the stages vary in what they entail, the carry the same idea of progressive development. Jean Piaget was born September 16, 1980, in Switzerland. His research found â€Å"that the growth of knowledge is a progressive construction of logically embedded structures superseding one another by a process of inclusion of lower less powerful logical means into higher and more powerful ones up to adulthood. Therefore, children s logic and modes of thinking are initially entirely different from those of adults† (Smith, 2000). On the other hand, there’s the theory of Erikson, born in Germany in 1902. His theory saying, â€Å"Developmental progression — from trust to autonomy, initiative, industry, identity, intimacy, generativity, and i ntegrity — was conceived as the sequential reorganization of ego and character structures. Each phase was the potential root of later health and pathology. By focusing on the social as well as the psychological, Erikson’s stages represented a quantum leap in Freudian thought, which had emphasized the psychosexual nature of development† (EI, 2013). Both theories are equally interesting. Although only slightly different, they both advocate for the nurture side of nature versus nurture debate. â€Å"Before Piaget’s work, the common assumption inShow MoreRelatedAnalysis Of Eriksons Theory On Early Childhood Education1212 Words   |  5 PagesIntroduction Jean Piaget once asked, â€Å"Are we forming children who are only capable of learning what is already known?† With there being so many theoriest whose research and ideas have made an impact on early childhood education.
