Real anatomical studies were not resumed until the thirteenth century. Herophilus and Erasistratus, for example, examined sensory nerves, motor nerves, and tendons in order to understand their functional differences. Typically it is conducted for advancement in scientific research, to test products and food before going out into the market, to find treatments or test medical drugs, and to protect people and the environment. This coincides with the role placed on physicians of the time to not act as scientists. More attention was paid to such matters in the following centuries. Erasistratus believed that fluids, when drunk, passed through the esophagus into the stomach.

Erasistratus is said to have natural philosophical views as compared to others during the time, paving the way for the teaching of methodologists in the field of medicine. Erasistratus understood that the heart served as a pump, thereby dilating the arteries, and he found … Virtual three-dimensional models have been recently fabricated as accurate replicas of the anatomical structures thanks to advances in rapid prototyping technology. 322 BC) and Erasistratus, (304 – 258 BC), performed. Egyptians believed in the need of an intact bodyfor the afterlife--hence mummification. It is clear from Galen that Erasistratus vivisected animals, and these dissections enabled him to draw parallels between men and beasts.

This theory of plethora then was why many of his treatments pertained to diet, fasting, and use of drugs that would change digestion. Comparative anatomy is a related field in which the structures of different animals are studied and compared. , Erasistratus and Galen both supported the theory of pneuma, however their beliefs on how pneuma acquired the air it needed differed.  Pliny says he was the grandson of Aristotle by his daughter Pythias, but this is not confirmed by any other ancient writer; and according to the Suda, he was the son of Cretoxena, the sister of the physician Medius, and Cleombrotus.

Greek physician Galen also conducts experiments on animals to advance the understanding of anatomy, physiology, pathology, and pharmacology. Experimentation on animals help scientists increase knowledge about the way the human body works. In Rome, Galen (130-200 A.D.) used them to demonstrate blood circulation. The first scientific Hellenic Society for Rheumatology (ERE) was established in 1960 and today ERE having been merged with the Professional Union of Greek rheumatologists (EPERE) is known as ERE-EPERE. , Erasistratus is frequently mentioned in historical documents with other significant figures of both his time period of the 3rd and 4th century BC and afterwards thanks to his accomplishments and advancements in the field of medicine.

Experimentation on animals goes way back since the beginning of time. Techniques for noninvasively viewing the human body, such as magnetic resonance imaging, opened up new ways of exploring and understanding anatomy, physiology, and disease pathogenesis.  Before that, nearly the only way to learn about the work was by analyzing Galen's works, which mention Erasistratus. Greek physician-scientists, such as Aristotle, (384 – 322 BC) and Erasistratus, (304 – 258 BC), performed experiments on living animals. See our list of anatomy research paper topics. Most of the students found their experience with cadaver exciting, as they were thrilled about the experience.

The oldest form of animal testing has been dated back to around 199-217 AD. Animals have been used to aid biomedical research for centuries. While Aristotle carried out his experiments on animals in the 4th century BCE, the 3rd century BCE was marked by the … Medical scientists therefore has responsibility of ensuring that any animal that they use for research should be protected. In this study the behaviour of medical students was analyzed during their MBBS course. on the island of Ceos (Chios), and died c. 250 B.C.
