Introduction: Dissections are performed on preserved animals donated specifically for science education in order to provide a hands-on experience to observe and study anatomy of an animal in three dimension, unlike a textbook, and how the organ systems are interconnected. In this particular dissection a fetal pig was used because the organs present in a pig, and their position in the body are similar to those of humans which provides insight on how human organs systems work overall and why they

early Gothic towers were built from 1210-1250 AD each 223 feet high. The west façade also consists of three levels surmounted by a row of twenty eight kings from the Old Testament. While the east façade features large clerestory windows held by single-arch flying buttresses. Basic cathedral architecture dictates a building of longitudinal space with three or more parallel structures of which the central structure rises above the other two and is lit by windows on both sides on the upper part. As Gothic

In 476 CE marks the fall of the Roman Empire and Western Europe has become fractured. By the twelfth century, a collection of Italian republics is forming and began to renew Europe and engineer the blueprints for today’s modern Western world. This period is called the Renaissance, a time of great invention and cultural change in Europe. During the Renaissance, one of the remarkable changes was in the fields of architecture, art and science. Unlike the conformity of the early Middle Ages in terms

Aberrant right subclavian artery (ARSA) is the most common aortic arch anomaly. The estimated incidence is 0.5-2%. They are often asymptomatic, but approximately 10% of people may complain of dysphagia lusoria4 or other compressive symptoms. In ARSA of the Innominate artery, the right subclavian artery arises as its own branch from the aortic arch distal to the origin of the left subclavian artery. Its relationship to the esophagus is variable with 80% posterior to esophagus, 15% between the esophagus

The three most basic types of bridges are beam, arch, and suspension bridges. These three bridges differ in things such as design and length, and they are used all around the world in order to connect us to our surroundings. The arch bridge is a semicircular structure that diverts the weight from the bridge deck to one of two abutments on each end. The larger the degree of curvature, the more tension is placed upon the underside. Its structure distributes compression onto the abutments which directly

2017 Argumentative A Thoracic Aortic Dissection Repair is More Complicated and Risky than a Heart Transplant Many people believe that a heart transplant is more complicated and risky than most surgeries because it involves removing the diseased heart and replacing it with a healthy heart. Although this surgical procedure is very difficult compared to most surgeries, a thoracic aortic dissection repair is more risky, complicated, and challenging. A thoracic aortic dissection is a serious condition

Introduction As an advanced practice nurse, one is bound to be faced with various ethical legal dilemmas that in most cases require urgent decision making that involve both moral and ethical considerations. Ethical dilemmas are basically situations where there are two available courses of action that completely contradict each other. The nurse has no choice but to make a decision between the two choices because each of the two decision choices is equally urgent and each of them seems to be the right

Juliette Mason is a High school student who has Marfans Syndrome. She plays basketball on her high school team and her parents were worried about her due to the fact that her brother had Marfans and died from an aortic aneurysm, he also played basketball. They came to me to find out how basketball will be impacted by the disorder and how she should go forward when she eventually has children.   Marfans Syndrome is a genetic disorder that affects the bodies connective tissue in the body. Connective

Disadvantages Even though the advantages outweigh the disadvantages of informed consent, it is still vital to talk about the shortcomings involved. It is important for health care professionals to understand the disadvantages of informed consent just as much as the advantages so that they can prevent these drawbacks, if possible. The disadvantages I will be discussing in this section is the act of coercion and undue influence, emergency situations and special circumstances where informed consent

Adding a fence to your property is one of the most significant improvements you can make to your home or business. When choosing a type of fence material, consider that chain link fencing continues to be popular among homeowners and business owners. If you’re considering a chain length fence, here are some reasons to choose it, as well as options and considerations. Benefits of a Chain Length Fence Chain length fences offer many benefits such as: • Affordability is one of the main advantages of having

COMPARATIVE ANATOMY OF AORTIC ARCHES IN VERTEBRATES DEFINITION: Aortic arches are also called as pharyngeal arteries. They are vascular structures that emerge from the ventricle of the heart. There are 6 pairs of these arches in embryonic stages which give rise to several major arteries later. They arise from the aortic sac and are present on the ventral and dorsal aorta. As discussed earlier that there are 6 pairs of aortic arches present in embryonic stages giving rise

Aortic Dissection: Hemiarch Versus Total Arch Replacement Taylor Aubin Sinclair Community College October 1, 2015 Aortic dissection is a life threatening condition in which the intima, the inner most layer, of the aorta tears. As the blood flows through the aorta it rushes through this tear resulting in dissection of the intima from the media, the middle layer of the aorta. This unfortunate condition is often fatal if the newly created false lumen ruptures through the aortic wall. Aortic

Treatments for Thoracic Aortic Aneurysm Early diagnosis of a thoracic aneurysm is critical to managing the condition. The larger the thoracic aortic aneurysm, or the faster it grows, the more likely it is to rupture. The risk of rupture increases when the aneurysm is larger than about twice the normal diameter of a healthy aorta blood vessel. As I said awhile ago there is no symptoms so diagnosing with thoracic aneurysm is very difficult, and often the condition goes undiagnosed until a rupture

monitoring and controlling them. The brain and nervous system are able to control both the heart rate and blood pressure due to the two carotid sinuses, that are located in the right and left carotids, and the aortic arch. The nerve endings on the outer layer of both the carotid sinuses and the aortic arch form two different nerves, which are known as baroreceptors. Baroreceptors, or receptors for pressure, send information concerning what is happening in blood vessels, particularly about stretch. The more

from the aorta, the largest artery in the body. The aorta curves above the heart before running down the front of the backbone. “The brachiocephalic artery, also known as the brachiocephalic trunk or innominate artery, is much shorter than the aortic arch and splits into two to form the right subclavian artery and the right common carotid

located between the atria and ventricles are known as atrioventricular valves (or cuspid valves), and the valves located at the bases of the large vessels leaving the ventricles are called semilunar valves (or pulmonary valve for the right side and aortic valve for the left side). Each set of valves carry out their functions so that regurgitation does not occur. For example, when the ventricles contract, atrioventricular calves close to prevent blood from flowing back into the atria. In contrast to

The thoracic oesophagus is situated a little to the left in the superior mediastinum between the trachea and the vertebral column. It passes behind and to the right of the aortic arch to descend in the posterior mediastinum along the right side of the descending thoracic aorta. Below, as it inclines left, it crosses anterior to the aorta and enters the abdomen through the diaphragm at the level of the tenth thoracic vertebra. From above downwards, the trachea, right pulmonary artery, left main bronchus

buddies for their input. He carried it around in a gym bag. Then he finally had a thought. He said that instead of making an incision on the left side that he would make on the right side. He also thought that for since the defect was a double aortic arch that he should cut into the right side. He said that the model helped him feel better about the surgery on Mia. He also said that if he did not have the model of her heart that he would probably have made the wrong cut. He said that using the model

ORTNER'S SYNDROME - A RARE CAUSE OF UNILATERAL VOCAL CORD PARALYSIS Abstract Patient presented with hoarseness due to vocal cord paralysis secondary to cardiovascular pathology is an extremely rare entity, better known as cardiovocal syndrome or Ortner's syndrome. The common underlying pathology was described as an enlargement of the left atrium or recurrent laryngeal nerve compression by the pulmonary artery. We report a case of undiagnosed congenital heart disease in a young lady presented to
