Flashcards in Ch1-P3-9 Deck (24):


(460-375BC) Greek physician considered "father of medicine". Established Hippocratic Oath the code of ethics for physicians. He urged physicians to stop saying that gods and demons caused disease and to seek the natural cause of disease which could be only rational basis for therapy.



(384-322BC). First philosopher to write about anatomy and physiology. He believed diseases and other natural events had either supernatural causes (theologi) or natural causes (physici or physiologi)


Claudius Galen

(130-200) Physician to Roman Gladiators who wrote most influential medical textbook of ancient era - the book was excessively worshipped by medical professors for centuries.


Moses ben Maimon known by Christians as Maimonides

(1135-1204) Jewish physician. Born in Spain and fled to Egypt at 24 to serve as physician to sultan Saladin. An admired Rabbi he wrote volumes on Jewish law and theology and wrote 10 influential medical books and numerous treatises on specific diseases.


Ibn Sina

(980-1037) known in west as Avicenna or "the Galen of Islam". He studied Galen and Aristotle. Wrote "the Canon of Medicine" which was leading text in European medical schools for over 500 years.


Andreas Vesalius

(1514-64) He taught anatomy in Italy. He wrote the first Atlas of Anatomy called "On the structure of the Human Body" in 1543.


William Harvey

English man (1578-1657) in physiology area studied blood circulation and along with Spanish man Michael Servetus (1511-53) were first Westerners to realise that blood must circulate continuously around body from heart to other organs and back to the heart.


Robert Hooke

Englishman (1635-1703). Designed various kinds of scientific instruments and improved compound microscope. He shaved cork and saw cells which he named. He published microscope book called Micrographia in 1665. Microscope strength 30x.


Antony van Leeuwenhoek

Dutch textile merchant (1632-1723) made stronger microscope 200x. He was keen observer of things on micro scale.


Carl Zeiss and Ernest Abbe

Two Germans Zeiss (1816-88) and Abbe (1840-1905) greatly improved compound microscope.


Matthias Schleiden and Theodor Schwann

Germans, Schleiden (1804-81) and Schwaan (1810-82) both concluded that all organisms were composed of cells.


Cell Theory (wikipedia)

1. All living organisms are composed of one or more cells.
2. The cell is the basic unit of structure, function, and organization in all organisms.
3. All cells come from preexisting, living cells.


Scientific method

 techniques for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.


Inductive Method

First prescribed by Englishman Francis Bacon (1561-1626). A process of making many observations until people can draw generalisations and predictions from them.


Hypothetico-Deductive Method

First, formulate a hypothesis which must be consistent with what is already known and capable of being tested and possibly falsified. Then, a deduction is made in form of "if-then". Ie, If hypothesis correct then sun should rise tomorrow.



Means that if we claim something is scientifically true, we must be able to specify what evidence it would take to prove it wrong. If nothing could possibly prove it wrong, then it is not scientific.


Sample size?

The number of subjects used in a study.


Control group

Consists of subjects as close to the treatment group as possible except they don't get the treatment.


Psychosomatic affect on experimental results?

These effects (effects of the mind on physiology) can have undesirable affect on experimental results if we don't control for them. It is therefore customary to give control group a placebo.


How is one way for experimenter bias to be stopped?

By using the double-blind method which is when neither the subject, nor the person giving them the treatment and recording the results, knows who is getting the treatment or the placebo.


Peer review?

A critical evaluation by other experts in the field.


Facts, Laws and Theories. What is a Fact?

Information that can be independently verified by any trained person - for example the fact that an iron deficiency leads to anemia.


A law of nature?

A generalisation about the predictable ways in which matter and energy behave. Ie Boyles Law, or Law of complementary base pairing where in DNA double helix adenine always pairs with thymine and guanine always pairs with cytosine.



An explanatory statement or set of statements derived from facts, laws and confirmed hypotheses. Ie Cell Theory. Theory summarises what we already know and suggests directions for further study.
