To prosect the organs I first bluntly dissect the aorta from the back of the organ block. Next, I detach the aorta from the heart by cutting the aorta at the aortic arch. The aorta is opened longitudinally and the interior examined for atherosclerosis, other pathologies and any medical devices. Then, I cut the esophagus from the larynx and bluntly dissect the esophagus away from the organ block, leaving it attached to the stomach. Next, the spleen is detached, weighed and serially sectioned perpendicular to the long axis. Next, I locate the kidneys and remove them from their capsule. I make sure to comment on how the capsule removes from the external surface of the kidney. I then weigh each kidney and bivalve them. Each kidney is serially section …show more content…
Then each lung needs to be weighed and the bronchial tree opened. The bronchi are examined for any masses or foreign material. The lungs are then serially sectioned perpendicular to the long axis. The parenchyma needs to be examined and any pathology documented. Next, the thyroid is removed and each lobe serially sectioned. Following the removal and sectioning of the thyroid, the larynx is opened longitudinally along its posterior surface. To view the interior of the supra, infra and glottic regions of the larynx the prosector needs to break the thyroid and cricoid cartilage. The interior should be inspected for any pathologies including masses or foreign material. Next, the pericardial sack needs to be opened and the heart detached from the pericardial sac. After detachment, the heart needs to be weighed and the coronary arteries need to be located and serially sectioned while still attached to the heart. The condition and amount of atherosclerosis of the coronary arteries need to be recorded. Finally, the apex of the heart is then sectioned perpendicular to the long axis to the base of the papillary …show more content…
The approach to opening the urinary bladder depends on the sex of the patient. If the patient is male, I locate the prostate and prostatic urethra. I then place a probe into the prostatic urethra. I use the probe as a guide to cut open the urinary bladder. Once the urinary bladder is opened, the prostate can be amputated, weighed and serially sectioned. If the patient is female, I locate and remove the uterus, ovaries, tubes and cervix. The uterus and ovaries need to be weighed opened. The condition of the endometrium, myometrium and ovaries needs to be noted. Occasionally these organs have been removed in which case I move on to opening the urinary bladder. Finding the bladder is more difficult in females because there is no prostate to serve as a guide. In both male and female patients, once the urinary bladder is opened the internal surface needs to be examined and observations recorded. After the organ block has been prosected, standard sections of each organ should be submitted for microscopic review along with any pathologies found.
I do not prosect the brain. However, I do remove the brain and weigh it. It is then suspended in formalin by placing string under the circle of Willis vasculature or by placing it in a fine mesh surgical cap. Then a paper towel is placed over the top of the brain and the container is closed and the brain is allowed to fix for two weeks before it is sectioned by a

Vesalius

...change. At an early age Vesalius showed an interest in dissection, when he later pursued his studies at the University of Paris he still held a fascination with dissection and therefore devoted his attention largely to anatomy. Once receiving his degree he was immediately offered a position as a lecturer on surgery and anatomy at Padua. Vesalius then later became part of the court of Emperor Charles V by the title of imperial physician. After many anatomical contributions, during Vesalius' pilgrimage he death occurred. While there is no fine historical report to as why he perished on his return, it is said that he became ill upon the ship and had passed away on the Greek island of Zacynthus. Vesalius is referred to as the founder of modern anatomy not only for his contributions to the knowledge of human physical internal structure, but for changing the thought and perception of anatomy as a whole. During his period Vesalius not only contributed major findings, he challenged a figure who no one had yet to go against the word of; the father of modern medicine Galen. Vesalius had discovered during his studies that Galen had preformed his dissections on apes and such mammals on the assumption that they are physiologically the same as humans. Though this was not fault of Galen's due to how the church viewed human dissection at the time which was deeply frowned upon. With a more open view Vesalius was able to conduct human dissections and prove that what was once accepted by Galen was...

Dissection Paper

...Wayne Fleming Goodnight 1-A DISSECTION: What is dissection? For some the procedure has solved some of the mysteries of life, for others it was simply mysterious and cruel. But by definition, dissection is the observing or cutting into a dead animal for the purposes of learning anatomy or physiology. In other words,Myth vs. Reality. There are also many other questions that students and others may have about dissection. There are many arguments as to whether it is necessary for the student's education or inhumane. Therefore, this act should stop completely. Through my research I have found that it is both necessary for learning and it can be inhumane. At which, another choice or alternative should always be available for the student who is not willing to dissect and at no expense to their grade.Many advances in medicine and in the understanding of how organisms function have been the direct result of animal dissection. Aristotle who revealed anatomical differences amoung animals by dissecting them performed some of the earliest recorded studies involving animals. In the United States dissections were common in colleges as early as the late 1800s. Myth vs. Reality Nevertheless, rebellion has been growing in the science laboratories of the nation's schools as a growing number of students refuse to dissect.Dissection is a way of separating or dividing into parts or pieces. Dissection is being called the way of discovery in understanding human anatomy, know and form, and human...

Anatomy

... and Hindus made no serious attempt to learn anatomy because they were interested in the supernatural world, not the natural one, and their cultures placed strong religious restrictions against debasing the body. Any anatomical dissections that were performed on animals were made to "study" organs in an effort to predict the future and to tell fortunes. *The Stone Age, the earliest known period of human culture, is characterized by the use of small stone tools. Anatomy in Ancient Greece The systematic study of anatomy may have begun in the fifth century B.C ., with the work of two Greek scientists, Alcmaeon (ca. 500 B.C.) in Italy andEmpedocles (ca. 490-430 B.C) in Sicily, where Greek culture and science flourished. Alcmaeon was probably the first person to dissect the human body for research purposes, and he is also given credit for proposing that the brain is the center of intelligence. Empedocles, who believed that the heart distributed life-giving heat to the body, initiated the idea that an ethereal substance called pneuma, which was both life and soul, flowed through the blood vessels. Although such early anatomists were often incorrect, their work was essential to the development of later scientists. Anatomical inferences without dissection continued in Greece with Hippocrates (ca. 460-377 B.C ), who is known as the Father of Medicine. (Many medical students still take the Hippocratic Oath upon graduation from medical school.) He might also be called the Father of Holistic...

The History and Use of Cadavers

...two-hundred years, dissection of the human cadaver has been the gold standard for teaching aspiring medical professionals the networking and layout of the human body. Surprisingly, cadaver usage has had a rather curious history. The use of a human cadaver dates back to 300 B.C. with the Greek physician and father of anatomy, Herophilos, who is noted as being the first person to dissect a human cadaver (Korf & Wicht, 2004). Herophilos’ anatomical discoveries were no small matter. Because of his dissections, we know that the brain is center of the nervous system and where its ventricles lie. We also know where the route taken by sinuses of the dura matter. Thanks to Herophilos, nerves are able to be distinguished from both tendons and blood vessels, as well as separated into motor or sensory. With his dissection of cadavers, we were given meticulous accounts of the different layers and sections of the eye, pancreas, liver, genitals, and stomach (Herophilus, 2013). Sadly, it seemed as if cadaver dissection died with Herophilos in 280 B.C. However, if we fast-forward to the 17th and 18th centuries, we will see a small resurgence of cadavers when certain theaters saw fit to put them on display (Korf & Wicht, 2004). Macabre, or ingenious artists (depending on how one views the situation) such as Michaelangelo and da Vinci, were known to have dissected cadavers to better portray their art (Dyer & Thorndike, 2000). It would seem that cadaver dissection had completely fallen...

Is Miss Gee Ultimately a Comical Poem?

...Comical Poem? In many ways, Miss Gee can be interpreted as a comical poem. Auden sustains a light hearted tone throughout, the traditional ABCB rhyming scheme imitates the format of a nursery rhyme providing a childish and facetious feel. The reader may also find Miss Gee’s inappropriate dream, implying her squalid, sexual encounters with the vicar comical. However, it could be argued Auden has used this light hearted, humorous tone to emphasise the harshness of the judgemental and uncaring society and make the audience question themselves for cruelly laughing at her unfortunate demise. At first glance, when reading the poem, the reader would not suspect it to lead to her death, with almost horrific details of the surgeon’s butchering dissections. This is due to the light hearted, nursery rhyme like tone through Auden’s use of short rhyming lines with heavy description of Miss Gee’s appearance. ‘She had a squint in her left eye / Her lips they were thin and small’. The descriptions give Miss Gee a ‘cartoon-esque’ impression and again make her and the overall poem appear quite comical. The fifteenth stanza, on line 59, ‘O, doctor, I’ve a pain inside of me’ although not a humorous line in itself, imitates the structure of the infamous ‘doctor, doctor’ jokes, making Miss Gee’s illness almost laughable. Many would argue and say that the blunt lines do not make the poem come across as funny, but uncomfortable and give the reader a sense of unease. Miss Gee’s abrupt and casual death...

Qf4020

...different types of organs and what they were used for. A man called Galen learned about the human body by dissecting the body. However, this wasn’t allowed as human dissection was banned in Alexandria so he dissected an animal. His theory for human anatomy had some errors because he used an animal to figure out how the human body works. Animals and humans have different functions so Galen’s theory for human anatomy was false. To learn about animal anatomy, Galen chopped off a pig’s head and tested the nerves in the pig to prove what each one was used for. So the knowledge of anatomy had some problems. Ancient Egypt knew about where the organs were in the human body. On the other hand, Egyptians didn’t know what they were used for. This is because Egyptians believed their was life after death so they produced embalming. Embalming is where you take organs of the body and use it for the afterlife. Egyptians used to get organs from dead humans such as: the heart, brain and lungs. They would wrap in linen. This was not good because they didn’t dissect the organs so they didn’t know what they were used for. They especially didn’t know what the heart and brain were used for as they used the organs for the afterlife so Egyptians didn’t know what the organs were used for as they didn’t dissect the organs or body. In conclusion, the period that saw the most improvement in surgical and anatomical knowledge was Ancient Rome. This is because they know what the organs were used for in a...

Letter Apposing Vivisection

...New Charter Academy, Broadoak Road, Ashton-U-Lyne, OL6 8RF 24th February 2014 Bridge Street, Westminster, London, SW1A OAA Dear David Heyes, I am writing to you concerning the ever growing issue of animal testing and vivisection. For hundreds of years animals have been tampered with and killed for one reason alone - to satisfy our medicinal tenacities. Over 600,000 animals have been used this year alone; this figure is astounding and utterly shocking! These vulnerable, exposed creatures languish in pain everyday of their lives. Can you imagine living like this? After reading an article by Peter Tatchell, a human rights campaigner, it has intrigued and inspired me to make people aware of this urgent subject. I hope, after reading what I have to say, you will raise this issue in Parliament. As humans, how can we treat another being so horrendously? The pain that is inflicted on these un-consenting animals is the basis of my...

...gained a reputation as a good anatomist, gaining a good knowledge of the structure of the body by examining skeletons. 3. When and where was Andreas Vesalius born? 4. How could his family background have influenced his decision to study medicine? 5. In which area of medicine did Vesalius excel? The Church now allowed human dissection, but did not allow bodies to be boiled up to produce skeletons. Vesalius desperately wanted to examine the human skeleton. The only way he could do this was to wait until the bodies of hung criminals had decomposed on the gallows. When the bones were bare he would remove the bodies and smuggle them back into town to study them. 6. What was the Church’s position on dissection at this time? 7. How did Veslius secure human skeletons for study? Vesalius was so successful that he became Professor of Surgery (responsible for teaching anatomy) at Padua University when he was just 23. At this time, the Catholic Church said that the works of Galen were inspired by God. So, in the universities of Europe, anatomy was taught by professors who simply read aloud from Galen’s books. If dissections took place they were usually carried out by Barber...

Chicken Leg Dissection Lab Report

...The beginning of the Chicken Leg Dissection Lab was a chicken leg placed on the tray. The fibula and the tibia bone of the chicken’s leg was dissected for this lab. On the outside of the leg, it had bumpy skin, had white spots which is probably the cartilage, ligament, and the fat. And the bone was also shown. The muscle was exposed on one of the sides. We soon begin the procedure. The skin and fascia was cuted by a scissor and pulled down gently to the bottom of the leg. We then examine the meat or also know as the muscle. It was smooth and was pink and red. Cutting through the meat, the tendons was shown. It was strong, white, and like a sturdy string. After all the meat was cut off and pulled down to the bottom of the bone, the bone was...

Summary Response Paper: Walker Percy’s “the Loss of the Creature”

...In his article “The Loss of The Creature,” Walker Percy presents the case that human or “creature’s” experiences are most often trivial because of our preconceived notions. Percy believes we can only truly enjoy these experiences if we leave the “beaten track.” Only then can we see the true beauty of the experience. Percy gives three examples to prove his point. His first example describes a tourist’s plans to go see the Grand Canyon. Oftentimes, tourists have preconceived expectations about the wonder, and feel that they are let down with a dreary sight rather than the miraculous wonder they have fantasized. The second example Percy uses is of a couple who, while wandering through Mexico looking for an “unspoiled” place (a place which has not been tainted by modernism), get lost. They stumble upon an Indian village and live with the locals for a little while. After returning home, they tell their friends that they had an experience better than they expected. The third example Percy uses is that of a biology teacher who gave his students a dogfish to dissect. The students look at the dogfish as another specimen to be dissected for a grade instead of trying to learn about it as a piece of unexplored creation. In his article “The Loss of The Creature,” Walker Percy attempts to show how in our experiences we do not really see what we think we see. I believe he was correct in. However, I did not always believe this. When I first read “The Loss of The Creature,” it did not make...

The Last Stop and Their First Patient

...descriptive throughout and his descriptions were helpful to me as the reader. He asks a lot of questions such as, “What, exactly, would science do with me?” He questions whether or not his body would be appreciated by the students, “Would my remains be unceremoniously tossed out in the orange biohazard trash container?” There’s a quote that mentions that the bodies wanted to be there so they could be a gift to science. It seems like he includes this to give himself comfort and peace of mind. He’s very descriptive and honest, without being overly graphic and gruesome. I believe he is respectful of all values. He describes how the process of human dissection is a gentle and respectful process, “The moment between the living and the dead is remarkably gentle.” He also ends his piece with how there’s a memorial service when the human dissection is complete. His piece lacks humor, but paints a vivid picture that describes something that most people never have the chance of seeing firsthand. There is a great deal of respect and understanding for the dead in this piece. “The Last Stop” by Brian Cable uses a lot more humorous elements, but isn’t offensive or too over-the-top. One of the first humorous remarks I noticed was, “What the hell, I though, mortuaries are concerned with time, too.” As I read the piece, I could tell that Cable was uneasy because early in the story he mentions that “mortality reminds us all too vividly of our own.” He uses very visual descriptions, music like...
