The field of anatomy at this point was in chaos the reason being that no one truly knew what animal tissues were made of. Zoology was seriously underdeveloped compared to botany and this was because animal cells were so much harder to see than plant cells. In fact, scientist did not realize that there were cells there at all and this gave rise to the notion that animal tissues must be fundamentally different from that of plants. But Theodore Schwann a zoologist, who was born in 1810 and died in 1882, was using an innovative way to stain animal tissue and also was utilizing his new Lister style microscope. Through Schwann’s research of animal tissue, he continued to find the same type of globular structure in all the different types of tissue …show more content…
The industrial revolution was in full swing and people now believed in machines and scientific laws. Subsequently a new generation of scientist wanted to know where new cells really came from and they wanted a mechanistic explanation that did not rely on cells simply springing forth from inanimate matter. Robert Remak, who was born in 1815 and died in 1865, was a polish Jew while his friend Rudolph Virchow, who was born in 1821 and died in 1902, was a politically savvy German. Robert Remak is not well known scientist but he did play a critical role in developing the final piece of cell theory. Remak was Jewish and so obtaining a professorship was always an uphill battle. He ultimately was forced to do his research in a run-down attic apartment in Berlin. Despite these obstacles Robert Remak set out to discover how new cells formed. Remak began his experiments and observations of cells in the 1840s he began by looking where he was sure to see lots of cells forming, the embryos of chickens. He used chick embryos because eggs were very inexpensive and the embryos of chicks are easily accessible. He would begin by cutting a blood vessel from the chick embryo and then pipetting by mouth the blood onto a microscope slide where he would observe the blood cells for hours. As he observed the blood from the chick embryo he saw cells that were going through different stages of cell division. Remak revealed his findings to his friend Virchow who thought it was interesting but ultimately must be a rare event that only applies to the red blood cells of developing chicks. This was hardly a major breakthrough according to Virchow and so Remak the diligent scientist that he was went to look for more evidence. Remak knew he needed to prove that this process occurred in other cells of other animals and so he picked frogspawn to study next. Remak through his
Patrick Dismuke was a teenage boy who had been a patient at Hermann Hospital all his life. He suffered from numerous health defects, including blood-clotting problems, malnutrition, and infection. On his journey, he learned to love the hospital, even more so than his home (perhaps due to the slight abandonment by his mother). He loved his doctors and nurses (most of them) and frequently spent his childhood playing games around the nurses’ station. The hospital staff equally loved Patrick, letting him watch movies late at night, allowing him to eat junk food, and answering his late night calls when he was lonely. Patrick’s love was so strong that he infected his own main line, the line leading directly to his heart, with
The Petitioner filed a motion for a new trial on the basis of newly discovered evidence disputing that the Government was negligent in disclosing a purported promise of leniency made to Robert Taliento, their key witness in exchange for his testimony. At a hearing on this motion, the Assistant United States Attorney, DiPaola, who presented the case to the grand jury admitted that he promised the witness that he would not be prosecuted if he testified before the grand jury and at trial. The Assistant (Golden) who tried the case was unaware of the promise. The defendant seeks to overturn his conviction on the grounds that this non-disclosure was a violation of his Due Process rights under the Fourteenth Amendment.
The book draws its name from the first essay, "The Lives of a Cell," in which Thomas offers his observations on ecology and the role of cellular activity. He writes that the "uniformity of the earth's life, more astonishing then its diversity, is accountable by the high probability that we derived, originally, from some single cell, fertilized in a bolt of lightning as the earth cooled" (3).

Once the external anatomy was observed the pig was then laid down on the dissection pan and held down by rubber bands exposing the ventral side of the pig. Then the cardiovascular and digestive systems were analyzed. The fetal pig did in fact have small teeth which were fairly sharp. Before the lab I wasn’t aware of the intricate details of the mouth cavity or that the kidneys were underneath the intestines. The hardest part was locating the trachea and the gall bladder. Additionally actually feeling the heart and various parts of the fetal pigs internal anatomy made learning the parts of the body
A healthy set of identical twin boys, Bruce and Brian Reimer were born in August of 1965 to Janet and Ron Reimer in Canada. At the age of eight months old, the twins were recommended to undergo a circumcision because they had a hard time urinating due to the condition phimosis. Unfortunately, during the procedure, the apparatus malfunctioned and it damaged Bruce’s penis. His parents then contacted Dr. John Money who was a medical psychologist at Johns Hopkins. He advised the Reimers to raise Bruce Reimer as a girl. Dr. Money convinced the parents that Bruce will be able to live a happy life as a girl because growing without a penis would be devastating. Bruce was named Brenda after the sex reassignment surgery at the age of 21 months old in 1967. Bruce was castrated and a vagina was constructed. The parents accepted their daughter and devotedly raised her as a girl named Brenda with help of the estrogen supplements to feminize the body and grow breast. The parents were ordered not to tell Brenda the truth of her gender.
Andreas Vesalius was well known for his dissections in the 1500’s. Growing up in Brussels he was captivated by the anatomy of animals. Throughout his childhood Andreas dissected many small animals trying to uncover life’s mystery. This curiosity regarding anatomy came very naturally, due to the fact that he was born into a family of physicians. Vesalius started his formal education at the University of Louvain; then traveled to Paris to continue his studies in medicine. During his life time, Vesalius was an accomplished physician, and professor of anatomy. He also received his degree as a doctor of medicine at the age of twenty-two. Vesalius writings and teachings set the foundation of anatomy we know today, hence why he received the title; founder of modern anatomy.

In Labs 22 through 26, my lab partner and I were assigned a fetal pig to perform a dissection on in order to understand anatomy, the study of an organism’s structure1, and physiology, the study of the functions and activities of a living organism2. Throughout these labs, we studied the structure of the fetal pig and performed experiments to understand four system processes: digestion, cardiovascular, respiratory, and excretory. Dissecting an organism, physically moving and seeing the different portions of the organism, especially of a fetal pig, is very important. This helps in the understanding of the skeletal structure and what series of physical and chemical processes the mammalian species body performs in order to survive.
In modern times, the experimentation on animals has led to just as many advances in medical science as there are in veterinary science and practice. Ibn Zuhr paved the way for basic surgical procedures that advanced over time as the anatomy of humans and animals were not seen as being one and the same. Blood transfusions came about through ...
One can almost feel the searing penetration of Lewis Thomas’ analytical eye as it descends the narrow barrel of the microscope and explodes onto a scene of vigorous, animated, interactive little cells—cells inescapably engrossed in relaying messages to one another with every bump and bounce; with every brush of the elbow, lick of the stamp, and click of the mouse…
In the late 1880s, genes, white blood cells, and aspirin were discovered. An Augustinian monk from Austria, Johann Gregor Mendel experimented in the crossplanting of pea plants. Eventually his research lead to the discovery of genes. In 1892, Elie Metchnikoff discovered phagocytosis. After observing the larvae of starfish, he found that mobile cells served as a defense for the organisms. This research on the cells lead him to believe that these cells swallow up and digest bacteria, therefore leading into the identification of white blood cells. Although it is unclear who deserves credit for the discovery of aspirin, Felix Hoffman and Heinrich Dreser are credited for the introduction. Both of them researched the drug while working for Bayer and they are credited for actually naming it "aspirin".

Anatomists, morphologists and biologists have tried to understand the way living creatures are living, and what they look like inside. Dr. Frourie in 1974 painfully cut organisms into thin slices, to study their internal arrangement to better understand them. Today, these people use CT scanners instead. It is a lot easier, less bloody, takes shorter time and the sample is not affected or destroyed during the procedure- the advantages are numerous. This technique enables us to visualize the inside of us humans, organisms or other objects in 3-D geometry.
In 1674 a man called Antony van Leeuwenhoek made a simple but useful microscope using only one lens to look at other tiny objects such as insects, yeast and to examine blood cells. Antony van Leeuwenhoek back round, to others, he would have been seen as an unpromising candidate to become a scientist of his time, due to him having no fortune, higher education or university degrees, but with his endless curiosity and an open mind he successfully came to make some of the most important findings in biology history, discovering bacteria, protists, sperm cells and many mor...
