Hippocrates father of modern medicine possibly most famous name in medicine

Romans: Conquered the Greeks and brought a lot of their ideas about healthcare into use across the Roman Empire.

Realized link between dirt and disease, built aqueducts to supply clean water and sewers to remove waste

Galen a Greek physician dissected animals to find out how their bodies worked, it was illegal to dissect humans. His knowledge led to improved techniques in surgery and new instruments

500-1400 middle ages

using herbal remedies and potions were seen as witchcraft and outlawed by the church, Laws were developed that required training in order to practice medicine

1347 outbreak of bubonic plague (highly

contagious pneumonia) considered punishment from God so nothing done to control rats that infested villages and towns carry the disease

700-1500 Arabic medicines

Refined Hippocrates theories and Islamic physicians began to use the regulation of diet, exercise and prescription of medicinal herbs to treat patients

Large hospitals were involved in training and licensing doctors and pharmacists (in Europe medicine was still governed by religion and superstition)

Used anesthetics by soaking sponges in narcotic drugs and placing over patients nose

1400-1700 The Renaissance

Andreas Versales dissected human bodies and Leonardo DaVinci made first anatomically correct drawings

Church did not permit dissection of “God fearing” bodies so it was often the bodies of criminals or “sinners” that were used, sometimes criminal was alive at beginning of dissection was a part of the punishment

William Harvey new theory heart acts as muscular pump circulated blood

Bubonic plague moved along trade routes from china and killed more than a third of Europe’s population

Vaccinations are now widespread and used to prevent diseases such as yellow fever, polio, measles, mumps, chicken pox and rubella

Medical imagining has improved significantly since the first x-rays, magnetic resonance imagery (MRI) ultrasound, computer tomography

(CAT scans) lead to early diagnosis and treatment increasing the rate of cures
